Chronology.

The start of the war in Europe is generally held to be 1 September 1939, beginning with the German invasion of Poland; the United Kingdom and France declared war on Germany two days later. The dates for the beginning of war in the Pacific include the start of the Second Sino-Japanese War on 7 July 1937, or even the Japanese invasion of Manchuria on 19 September 1931.  Others follow the British historian A.J.P. Taylor, who held that the Sino-Japanese War and war in Europe and its colonies occurred simultaneously, and the two wars merged in 1941. This article uses the conventional

Background.

Europe.

World War I had radically altered the political European map, with the defeat of the Central Powers—including Austria-Hungary, Germany, Bulgaria and the Ottoman Empire—and the 1917 Bolshevik seizure of power in Russia, which eventually led to the founding of the Soviet Union. Meanwhile, the victorious Allies of World War I, such as France, Belgium, Italy, Romania, and Greece, gained territory, and new nation-states were created out of the collapse of Austria-Hungary and the Ottoman and Russian Empires.  To prevent a future world war, the League of Nations was created during the 1919 Paris

Asia.

The Kuomintang (KMT) party in China launched a unification campaign against regional warlords and nominally unified China in the mid-1920s, but was soon embroiled in a civil war against its former Chinese Communist Party allies and new regional warlords. In 1931, an increasingly militaristic Empire of Japan, which had long sought influence in China as the first step of what its government saw as the country's right to rule Asia,

Pre-war events.

Italian invasion of Ethiopia (1935).

The Second Italo–Ethiopian War was a brief colonial war that began in October 1935 and ended in May 1936. The war began with the invasion of the Ethiopian Empire (also known as Abyssinia) by the armed forces of the Kingdom of Italy ("Regno d'Italia"), which was launched from Italian Somaliland and Eritrea. The war resulted in the military occupation of Ethiopia and

Spanish Civil War (1936–1939).

When civil war broke out in Spain, Hitler and Mussolini lent military support to the Nationalist rebels, led by General Francisco Franco. Italy supported the Nationalists to a greater extent than the Nazis did: altogether Mussolini sent to Spain more than 70,000 ground troops and 6,000 aviation personnel, as well as about 720 aircraft. The Soviet

Japanese invasion of China (1937).

In July 1937, Japan captured the former Chinese imperial capital of Peking after instigating the Marco Polo Bridge Incident, which culminated in the Japanese campaign to invade all of China. The Soviets quickly signed a non-aggression pact with China to lend materiel support, effectively ending China's prior co-operation with Germany. From September to November, the Japanese attacked Taiyuan, engaged the Kuomintang Army around Xinkou, and fought Communist forces in Pingxingguan. Generalissimo Chiang Kai-shek deployed his best army to defend Shanghai, but, after three months of fighting, Shanghai

Soviet–Japanese border conflicts.

In the mid-to-late 1930s, Japanese forces in Manchukuo had sporadic border clashes with the Soviet Union and Mongolia. The Japanese doctrine of Hokushin-ron, which emphasised Japan's expansion northward, was favoured by the Imperial Army during this time. With the Japanese defeat at Khalkin Gol

European occupations and agreements.

In Europe, Germany and Italy were becoming more aggressive. In March 1938, Germany annexed Austria, again provoking little response from other European powers. Encouraged, Hitler began pressing German claims on the Sudetenland, an area of Czechoslovakia with a predominantly ethnic German population. Soon the United Kingdom and France followed the appeasement policy of British Prime Minister Neville Chamberlain and conceded this territory to Germany in the Munich Agreement, which was made against the wishes of the Czechoslovak government, in exchange for a promise of no further territorial demands.

Course of the war.

War breaks out in Europe (1939–40).

On 1 September 1939, Germany invaded Poland after having staged several false flag border incidents as a pretext to initiate the attack. The Battle of Westerplatte is often described as the first battle of the war. The United Kingdom responded with an ultimatum to Germany to cease military operations, and on 3 September, after the ultimatum was ignored, France and Britain, along with their empires, declared war on Germany. As part of this, Australia, New Zealand, South Africa and Canada also joined the

Western Europe (1940–41).

In April 1940, Germany invaded Denmark and Norway to protect shipments of iron ore from Sweden, which the Allies were attempting to cut off. Denmark capitulated after a few hours, and Norway was conquered within two months despite Allied support. British discontent over the Norwegian campaign led to the appointment of Winston Churchill as Prime Minister on 10May 1940.  On the same day, Germany launched an offensive against France. To circumvent the strong Maginot Line fortifications on the Franco-German border, Germany directed its attack at the neutral nations of Belgium, the Netherlands, and Luxembourg. The Germans carried out

Mediterranean (1940–41).

In early June 1940 the Italian "Regia Aeronautica" attacked and besieged Malta, a British possession. In late summer through early autumn Italy conquered British Somaliland and made an incursion into British-held Egypt. In October Italy attacked Greece, but the attack was repulsed with heavy Italian casualties; the campaign ended within months with minor territorial changes. Germany started preparation for an invasion of the Balkans to assist Italy, to prevent the British from gaining a foothold there, which would be a potential threat for Romanian oil fields, and to strike against the British dominance of the Mediterranean.  In December 1940, British Empire forces began counter-offensives against Italian forces in Egypt and Italian East Africa. The offensives were highly successful; by early February 1941 Italy had lost control of eastern Libya, and large numbers of Italian troops had been taken, prisoner. The Italian Navy also suffered significant defeats,

Axis attack on the Soviet Union (1941).

With the situation in Europe and Asia relatively stable, Germany, Japan, and the Soviet Union made preparations. With the Soviets wary of mounting tensions with Germany and the Japanese planning to take advantage of the European War by seizing resource-rich European possessions in Southeast Asia, the two powers signed the Soviet–Japanese Neutrality Pact in April 1941. By contrast, the Germans were steadily making preparations for an attack on the Soviet Union, massing forces on the Soviet border.  Hitler believed that the United Kingdom's refusal to end the war was based on the hope that the United States and the Soviet Union would enter the war against Germany sooner

War breaks out in the Pacific (1941).

In 1939, the United States had renounced its trade treaty with Japan, and beginning with an aviation gasoline ban in July 1940, Japan became subject to increasing economic pressure. During this time, Japan launched its first attack against Changsha, a strategically important Chinese city, but was repulsed by late September. Despite several offensives by both sides, the war between China and Japan was stalemated by 1940. To increase pressure on China by blocking supply routes, and to better position Japanese forces in the event of a war with the Western powers, Japan invaded and occupied northern Indochina. Afterwards, the United States embargoed iron, steel and mechanical parts against Japan.  Chinese nationalist forces launched a large-scale counter-offensive in early 1940. In August, Chinese communists launched

Axis advance stalls (1942–43).

On 1 January 1942, the Allied Big Four—the Soviet Union, China, the United Kingdom and the United States—and 22 smaller or exiled governments issued the Declaration by United Nations, thereby affirming the Atlantic Charter, and agreeing not to sign a separate peace with the Axis powers.  During 1942, Allied officials debated on the appropriate grand strategy to pursue. All agreed that defeating Germany was the primary objective. The Americans favoured a straightforward, large-scale attack on Germany through France. The Soviets were also demanding a second front. The British, on the other hand, argued that military operations should target peripheral areas to wear out German

Pacific (1942–43).

By the end of April 1942, Japan and its ally Thailand had almost fully conquered Burma, Malaya, the Dutch East Indies, Singapore, and Rabaul, inflicting severe losses on Allied troops and taking a large number of prisoners. Despite stubborn resistance by Filipino and US forces, the Philippine Commonwealth was eventually captured in May 1942, forcing its government into exile. On 16 April, in Burma, 7,000 British soldiers were encircled by the Japanese 33rd Division during the Battle of Yenangyaung and rescued by the Chinese 38th Division. Japanese

Eastern Front (1942–43).

Despite considerable losses, in early 1942 Germany and its allies stopped a major Soviet offensive in central and southern Russia, keeping most territorial gains they had achieved during the previous year. In May the Germans defeated Soviet offensives in the Kerch Peninsula and at Kharkov, and then launched their main summer offensive against southern Russia in June 1942, to seize the oil fields of the Caucasus and occupy Kuban steppe, while maintaining positions on the northern and central areas of the front. The Germans split Army Group South into two groups: Army

Western Europe/Atlantic and Mediterranean (1942–43).

Exploiting poor American naval command decisions, the German navy ravaged Allied shipping off the American Atlantic coast. By November 1941, Commonwealth forces had launched a counter-offensive, Operation Crusader, in North Africa, and reclaimed all the gains the Germans and Italians had made. In North Africa, the Germans launched an offensive in January, pushing the British back to positions at the Gazala Line by early February, followed by a temporary lull in combat which Germany used to prepare for their upcoming offensives. Concerns the Japanese might use bases in Vichy-held Madagascar caused the British to invade the island in early May 1942. An Axis offensive in Libya forced an Allied retreat deep inside Egypt until Axis forces were stopped at El Alamein. On the Continent, raids of Allied commandos on strategic targets, culminating in the disastrous Dieppe Raid, demonstrated

Allies gain momentum (1943–44).

After the Guadalcanal Campaign, the Allies initiated several operations against Japan in the Pacific. In May 1943, Canadian and US forces were sent to eliminate Japanese forces from the Aleutians. Soon after, the United States, with support from Australia, New Zealand and Pacific Islander forces, began major ground, sea and air operations to isolate Rabaul by capturing surrounding islands, and breach the Japanese Central Pacific perimeter at the Gilbert and Marshall Islands. By the end of March 1944, the Allies had completed both of these objectives and had also neutralised the major Japanese base at Truk in the Caroline Islands. In April, the Allies launched an operation to retake Western New Guinea.  In the Soviet Union, both the Germans and the

Allies close in (1944).

On 6 June 1944 (known as D-Day), after three years of Soviet pressure, the Western Allies invaded northern France. After reassigning several Allied divisions from Italy, they also attacked southern France. These landings were successful, and led to the defeat of the German Army units in France. Paris was liberated on 25 August by the local resistance assisted by the Free French Forces, both led by General Charles de Gaulle, and the Western Allies continued to push back German forces in western Europe during the latter part of the year. An attempt to advance into northern Germany spearheaded by a major airborne operation in

Axis collapse, Allied victory (1944–45).

On 16 December 1944, Germany made a last attempt on the Western Front by using most of its remaining reserves to launch a massive counter-offensive in the Ardennes and along with the French-German border to split the Western Allies, encircle large portions of Western Allied troops and capture their primary supply port at Antwerp to prompt a political settlement. By January, the offensive had been repulsed with no strategic objectives fulfilled. In Italy, the Western Allies remained stalemated at the German defensive line. In mid-January 1945, the Soviets and Poles attacked in Poland, pushing from the Vistula to the Oder river in Germany, and overran East Prussia. On 4 February Soviet, British, and US leaders met for the Yalta Conference. They agreed on the occupation

Aftermath.

The Allies established occupation administrations in Austria and Germany. The former became a neutral state, non-aligned with any political bloc. The latter was divided into western and eastern occupation zones controlled by the Western Allies and the Soviet Union. A denazification programme in Germany led to the prosecution of Nazi war criminals in the Nuremberg trials and the removal of ex-Nazis from power, although this policy moved towards amnesty and re-integration of ex-Nazis into West German society.  Germany lost a quarter of its pre-war (1937) territory. Among the eastern territories, Silesia, Neumark and most of Pomerania were taken over by Poland, and East Prussia was divided between Poland and the Soviet Union, followed by the expulsion to Germany of the nine million Germans from these provinces, as well as three million Germans from the Sudetenland in Czechoslovakia. By the 1950s, one-fifth of West Germans were refugees from the east. The Soviet Union also took over the Polish provinces east of the Curzon line, from which 2 million Poles were expelled; north-east Romania, parts of eastern Finland, and the three Baltic states were incorporated into the Soviet Union.  In an effort to maintain world peace, the Allies formed the United Nations, which officially came into existence on 24 October 1945, and adopted the Universal Declaration of Human Rights in 1948 as a common standard for all member nations. The great powers that were the victors of the war—France, China, the United Kingdom, the Soviet Union and the United States—became the permanent members of the UN's Security Council. The five permanent members remain so to the present, although there have been two seat changes, between the Republic of China and the People's Republic of China in 1971, and between the Soviet Union and its successor state, the Russian Federation, following the dissolution of the Soviet Union in 1991. The alliance between the Western Allies and the Soviet Union had begun to deteriorate even before the war was over.  Germany had been "de facto" divided, and two independent states, the Federal Republic of Germany (West Germany) and the German Democratic

Impact.

Casualties and war crimes.

Estimates for the total number of casualties in the war vary, because many deaths went unrecorded. Most suggest that some 60 million people died in the war, including about 20 million military personnel and 40 million civilians. Many of the civilians died because of deliberate genocide, massacres, mass bombings, disease, and starvation.  The Soviet Union alone lost around 27 million people during the war, including 8.7 million military and 19 million civilian deaths. A quarter of the people in the Soviet Union were wounded or killed. Germany sustained 5.3 million military losses, mostly on the Eastern Front and during the final battles in Germany.  An estimated 11 to 17 million civilians died as a direct or as an indirect result of Nazi racist policies, including mass killing of around 6million Jews, along with Roma, homosexuals, at least 1.9 million ethnic Poles and millions of other Slavs (including Russians, Ukrainians and Belarusians), and other ethnic and minority groups. Between 1941 and 1945, more than 200,000 ethnic Serbs, along with gypsies and Jews, were persecuted and murdered by the Axis-aligned

Genocide, concentration camps, and slave labour.

Nazi Germany was responsible for the Holocaust (which killed approximately 6million Jews) as well as for killing 2.7 million ethnic Poles and 4million others who were deemed "unworthy of life" (including the disabled and mentally ill, Soviet prisoners of war, Romani, homosexuals, Freemasons, and Jehovah's Witnesses) as part of a programme of deliberate extermination, in effect becoming a "genocidal state". Soviet POWs were kept in especially unbearable conditions, and 3.6 million Soviet POWs out of 5.7 died in Nazi camps during the war. In addition to concentration camps, death camps were created in Nazi Germany to exterminate people on an industrial scale. Nazi Germany extensively used forced labourers; about 12 million Europeans from German occupied countries were abducted and used as a slave work force in German industry, agriculture and war economy.  The Soviet Gulag became a "de facto" system of deadly camps during 1942–43, when wartime privation and hunger caused numerous

Occupation.

In Europe, occupation came under two forms. In Western, Northern, and Central Europe (France, Norway, Denmark, the Low Countries, and the annexed portions of Czechoslovakia) Germany established economic policies through which it collected roughly 69.5 billion reichmarks (27.8 billion US dollars) by the end of the war; this figure does not include the sizeable plunder of industrial products, military equipment, raw materials and other goods. Thus, the income from occupied nations was over 40 per cent of the income Germany collected from taxation, a figure which increased to nearly 40 per cent of total German income as the war went on.  In the East, the intended gains of "Lebensraum" were never attained

Home fronts and production.

In Europe, before the outbreak of the war, the Allies had significant advantages in both population and economics. In 1938, the Western Allies (United Kingdom, France, Poland and the British Dominions) had a 30 per cent larger population and a 30 per cent higher gross domestic product than the European Axis powers (Germany and Italy); if colonies are included, the Allies had more than a 5:1 advantage in population and a nearly 2:1 advantage in GDP. In Asia at the same time, China had roughly six times the population of Japan but only an 89 per cent higher GDP; this is reduced to three times the population and only a 38 per cent higher GDP if Japanese

Advances in technology and warfare.

Aircraft were used for reconnaissance, as fighters, bombers, and ground-support, and each role was advanced considerably. Innovation included airlift (the capability to quickly move limited high-priority supplies, equipment, and personnel); and of strategic bombing (the bombing of enemy industrial and population centres to destroy the enemy's ability to wage war). Anti-aircraft weaponry also advanced, including defences such as radar and surface-to-air artillery. The use of the jet aircraft was pioneered and, though late introduction meant it had little impact, it led to jets becoming standard in air forces worldwide. Although guided missiles were being developed, they were not advanced enough to reliably target aircraft until some years after the war.  Advances were made in nearly every aspect of naval warfare, most notably with aircraft carriers and submarines. Although aeronautical warfare had relatively little success at the start of the war, actions at Taranto, Pearl Harbor, and the Coral Sea established the carrier as the dominant capital ship in place of the battleship. In the Atlantic, escort carriers proved to be a vital part of Allied convoys, increasing the effective protection radius and helping to close the Mid-Atlantic gap. Carriers were also more economical than battleships because of the relatively low cost of aircraft and their not requiring to be as heavily armoured. Submarines, which had proved to be an effective weapon during the First World War, were anticipated by all sides to be important in the second. The British focused development on anti-submarine weaponry and tactics, such as sonar and convoys, while Germany focused on improving its offensive capability, with designs such as the Type VII submarine and wolfpack tactics. Gradually, improving Allied technologies such as the Leigh light, hedgehog, squid, and homing torpedoes proved victorious over the German

World War II (often abbreviated as WWII or WW2), also known as the Second World War, was a global war that lasted from 1939 to 1945. The vast majority of the world's countries—including all the great powers—eventually formed two opposing military alliances: the Allies and the Axis. A state of total war emerged, directly involving more than 100 million people from more than 30 countries. The major participants threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. World WarII was the deadliest conflict in human history, marked by 70 to 85 million fatalities, most of whom were civilians in the Soviet Union and China. Tens of millions of people died during the conflict due to genocides (including the Holocaust), premeditated death from starvation, massacres, and disease. Aircraft played a major role in the conflict which included the use of terror bombing, strategic bombing and the only use of nuclear weapons in war.

Druhá světová válka byl globální vojenský konflikt v letech 1939–1945, jehož se zúčastnila většina států světa. Tento konflikt se stal s více než 62 miliony obětí na životech dosud největším a nejvíce zničujícím válečným střetnutím v dějinách lidstva.


Names.

Sun was born as Sun Wen (Cantonese: "Syūn Màhn"; ), and his was Sun Deming ("Syūn Dāk-mìhng"; ). As a child, his was Tai Tseung ("Dai-jeuhng"; ). Sun's courtesy name was Zaizhi ("Jai-jī"; ), and

Birthplace and early life.

Sun Wen was born on 12 November 1866 to Sun Dacheng and Madame Yang. His birthplace was the village of Cuiheng, Xiangshan County (now Zhongshan City), Guangdong. He had a cultural background of Hakka

Education years.

At the age of 10, Sun began seeking schooling, and he met childhood friend Lu Haodong. By age 13 in 1878, after receiving a few years of local schooling, Sun went to live with his elder brother, Sun Mei () in Honolulu. Sun Mei financed Sun Yat-sen's education and would later be a major contributor for the overthrow of the Manchus.  During his stay in Honolulu, Sun Yat-sen went to ʻIolani School where he studied English, British history, mathematics, science, and Christianity. While he was originally unable to speak English, Sun Yat-sen quickly picked up the language and received a prize for academic achievement from King David Kalākaua before graduating in 1882. He then attended Oahu College (now known as Punahou

Religious views and Christian baptism.

In the early 1880s, Sun Mei sent his brother to ʻIolani School, which was under the supervision of British Anglicans and directed by an Anglican prelate named Alfred Willis. The language of instruction was English. Although Bishop Willis emphasized that no one was forced to accept Christianity, the students were required to attend chapel on Sunday. At Iolani School, young Sun Wen first came in contact with Christianity. In his work, Schriffin speculated that

Transformation into a revolutionary.

Four Bandits.

During the Qing-dynasty rebellion around 1888, Sun was in Hong Kong with a group of revolutionary thinkers who were nicknamed the Four Bandits at the Hong Kong College

Furen and Revive China Society.

In 1891, Sun met revolutionary friends in Hong Kong including Yeung Ku-wan who was the leader and founder of the Furen Literary Society. The group was spreading the idea of overthrowing the Qing. In 1894, Sun wrote an 8,000 character petition to Qing Viceroy Li Hongzhang presenting his ideas for modernizing China. He traveled to Tianjin to personally present the petition to Li but was not

First Sino-Japanese War.

In 1895, China suffered a serious defeat during the First Sino-Japanese War. There were two types of responses. One group of intellectuals contended that the Manchu Qing government could restore its legitimacy by successfully modernizing. Stressing that overthrowing the Manchu would result in chaos

From uprising to exile.

First Guangzhou uprising.

In the second year of the establishment of the Revive China society on 26 October 1895, the group planned and launched the First Guangzhou uprising against the Qing in Guangzhou. Yeung Ku-wan directed the uprising starting from Hong Kong. However, plans were leaked out

Exile in Japan.

Sun Yat-sen spent time living in Japan while in exile. He was supported by the Japanese politician Tōten Miyazaki. Most Japanese who actively worked with Sun were motivated by a pan-Asian fear of encroaching Western imperialism. While in Japan, Sun also met and befriended Mariano Ponce, then a diplomat of the First Philippine Republic. During the Philippine Revolution and

Huizhou uprising in China.

On 22 October 1900, Sun launched the Huizhou uprising to attack Huizhou and provincial authorities in Guangdong. This came five years after the failed Guangzhou uprising.

Further exile.

Sun was in exile not only in Japan but also in Europe, the United States, and Canada. He raised money for his revolutionary party and to support uprisings in China. While the events leading up to it are unclear, in 1896 Sun Yat-sen was detained at the Chinese Legation in

Heaven and Earth Society, overseas travel.

A "Heaven and Earth Society" sect known as Tiandihui had been around for a long time. The group has also been referred to as the "three cooperating organizations" as well as the triads. Sun Yat-sen mainly used this group to leverage his overseas travels to gain further financial and resource support for his revolution. According to the New York Times "Sun Yat-sen left his village in Guangdong, southern China, in 1879 to join a brother in Hawaii. He eventually returned to China and from there moved to the British colony of Hong Kong in 1883. It was there that he received his Western education, his Christian faith and the money for revolution." This is

Revolution.

Tongmenghui.

In 1904, Sun Yat-sen came about with the goal "to expel the Tatar barbarians (i.e. Manchu), to revive Zhonghua, to establish a Republic, and to distribute land equally among the people" (). One of Sun's major legacies was the creation of his political

Malaya support.

Sun's notability and popularity extends beyond the Greater China region, particularly to Nanyang (Southeast Asia), where a large concentration of overseas Chinese resided in Malaya (Malaysia and Singapore). While in Singapore, he met local Chinese merchants Teo Eng Hock (), Tan Chor Nam () and Lim Nee Soon (), which mark the commencement of direct support from the Nanyang Chinese. The Singapore chapter of the Tongmenghui was established on 6 April 1906, though some records claim the founding date to be end of 1905. The villa used by Sun was known as Wan Qing Yuan. At this point Singapore was the headquarters of the Tongmenghui.  Thus, after founding the Tong Meng Hui, Dr Sun advocated the establishment of The Chong Shing Yit Pao as the alliance's mouthpiece to promote

Siamese support.

In 1903, Sun made a secret trip to Bangkok in which he sought funds for his cause in Southeast Asia. His loyal followers published newspapers, providing invaluable support to the dissemination of his revolutionary principles and ideals among Chinese descent in Thailand. In Bangkok, Sun

Zhennanguan uprising.

On 1 December 1907, Sun led the Zhennanguan uprising against the Qing at Friendship Pass, which is the border between Guangxi and Vietnam. The uprising failed after

Anti-Sun movements.

Because of these failures, Sun's leadership was challenged by elements from within the Tongmenghui who wished to remove him as leader. In Tokyo 1907–1908 members from the recently merged Restoration society raised doubts about Sun's credentials. Tao Chengzhang () and Zhang Binglin publicly denounced Sun with an open leaflet called "A declaration of Sun Yat-sen's criminal acts by the revolutionaries in Southeast Asia". This was

1911 revolution.

To sponsor more uprisings, Sun made a personal plea for financial aid at the Penang conference held on 13 November 1910 in Malaya. The leaders launched a major drive for donations across the Malay Peninsula. They raised HK$187,000.  On 27 April 1911, revolutionary Huang Xing led a second Guangzhou uprising known as the Yellow Flower Mound revolt against the Qing. The revolt failed and ended in disaster; the bodies of only 72 revolutionaries were found. The revolutionaries are remembered as martyrs.  On 10 October 1911, a military uprising at Wuchang

Republic of China with multiple governments.

Provisional government.

On 29 December 1911 a meeting of representatives from provinces in Nanking (Nanjing) elected Sun Yat-sen as the "provisional president" (). 1 January 1912 was set as the first day of the First Year of the Republic. Li Yuanhong was made provisional vice-president and Huang Xing became the minister of the army. The new Provisional Government

Beiyang government.

Yuan Shikai, who controlled the Beiyang Army, the military of northern China, was promised the position of President of the Republic of China if he could get the Qing court to abdicate. On 12 February 1912 Emperor Puyi did abdicate the throne. Sun stepped down as President, and Yuan became the new provisional president in Beijing on 10 March 1912. The provisional government did not have any military

Nationalist party and Second Revolution.

Tongmenghui member Song Jiaoren quickly tried to control the parliament. He mobilized the old Tongmenghui at the core with the merger of a number of new small parties to form a new political party called the Kuomintang (Chinese nationalist party, commonly abbreviated as "KMT") on 25 August 1912 at Huguang Guild Hall Beijing. The 1912–1913 National assembly election was considered a huge success

Political chaos.

In 1915 Yuan Shikai proclaimed the Empire of China (1915–1916) with himself as Emperor of China. Sun took part in the Anti-Monarchy war of the Constitutional Protection Movement, while also supporting bandit leaders like Bai Lang during the Bai Lang Rebellion. This marked the beginning

Path to Northern Expedition.

Guangzhou militarist government.

China had become divided among regional military leaders. Sun saw the danger of this and returned to China in 1917 to advocate Chinese reunification. In 1921 he started a self-proclaimed military government in Guangzhou and was elected Grand Marshal. Between 1912 and 1927 three governments had been set up in South

KMT–CPC cooperation.

By this time Sun had become convinced that the only hope for a unified China lay in a military conquest from his base in the south, followed by a period of political tutelage that would culminate in the transition to democracy. In order to hasten the conquest of China, he began a policy of active cooperation with the Communist Party of China (CPC). Sun and the Soviet Union's Adolph Joffe signed the Sun-Joffe Manifesto in January 1923. Sun received help from the Comintern for

Finance concerns.

In 1924 Sun appointed his brother-in-law T. V. Soong to set up the first Chinese Central bank called the Canton Central Bank.

Final speeches.

In February 1923 Sun made a presentation to the Students' Union in Hong Kong University and declared that it was the corruption of China and the peace, order and good government of Hong Kong that turned him into a revolutionary. This same year, he delivered a speech in which he proclaimed his Three Principles of the People as the foundation of the country and the Five-Yuan Constitution as the guideline for the political system and bureaucracy. Part of

Illness and death.

For many years, it was popularly believed that Sun died of liver cancer. On 26 January 1925, Sun underwent an exploratory laparotomy at Peking Union Medical College Hospital (PUMCH) to investigate a long-term illness. This was performed by the head of the Department of Surgery, Adrian S. Taylor, who stated that the procedure "revealed extensive involvement of the liver by carcinoma" and that Sun only had about ten days to live. Sun was hospitalized and his condition was treated with radium. Sun survived the initial ten-day period and on 18 February, against the advice of doctors, he was transferred to the KMT headquarters and treated with traditional Chinese medicine. This too was unsuccessful and he died on 12 March at the age of 58. Contemporary reports in "The New York Times", "Time", and the Chinese newspaper "Qun Qiang Bao" all reported the cause of death as liver cancer, based on Taylor's observation.  Following this the body then was preserved in mineral oil and taken to the Temple of Azure Clouds, a

Legacy.

Power struggle.

After Sun's death, a power struggle between his young protégé Chiang Kai-shek and his old revolutionary comrade Wang Jingwei split the KMT. At stake in this struggle was the right to lay claim to Sun's ambiguous legacy. In 1927 Chiang Kai-shek married Soong Mei-ling, a sister of Sun's widow Soong Ching-ling, and subsequently he

Cult of personality.

A personality cult in the Republic of China was centered on Sun and his successor, Generalissimo Chiang Kai-shek. Chinese Muslim Generals and Imams participated in this cult of personality and one party state, with Muslim General Ma Bufang making people bow to Sun's portrait and listen to the national anthem during a

Father of the Nation.

Sun Yat-sen remains unique among 20th-century Chinese leaders for having a high reputation both in mainland China and in Taiwan. In Taiwan, he is seen as the Father of the Republic of China, and is known by the

"Forerunner of the revolution".

On the mainland, Sun is seen as a Chinese nationalist, proto-socialist, first president of a Republican China and is highly regarded as the "Forerunner of the Revolution" (). He is even mentioned by name in the to the Constitution of the People's Republic of China. In recent years, the leadership of the Communist Party of China has

Economic development.

Sun Yat-sen spent years in Hawaii as a student in the late 1870s and early 1880s, and was highly impressed with the economic development he saw there. He used the independent Kingdom of Hawaii as a model to develop

Family.

Sun Yat-sen was born to Sun Dacheng () and his wife, Lady Yang () on 12 November 1866. At the time his father was age 53, while his mother was 38 years old. He had an older brother, Sun Dezhang (), and an older sister, Sun Jinxing (), who died at the early age of 4. Another older brother, Sun Deyou (), died at the age of 6. He also had an older sister, Sun Miaoqian (), and a younger sister, Sun Qiuqi ().  At age 20, Sun had an arranged marriage with fellow villager Lu Muzhen. She bore a son, Sun Fo, and two daughters, Sun Jinyuan () and Sun Jinwan ().

Sun Yat-sen (; born Sun Wen; 12 November 1866 – 12 March 1925) was a Chinese philosopher, physician, and politician, who served as the provisional first president of the Republic of China and the first leader of the Kuomintang (Nationalist Party of China). He is referred as the "Father of the Nation" in the Republic of China for his instrumental role in the overthrow of the Qing dynasty during the Xinhai Revolution. Sun is unique among 20th-century Chinese leaders for being widely revered in both mainland China and Taiwan.

History.

Origin.

The site had been continuously inhabited by Finno-Ugric peoples since the 2nd century BC. The Slavs occupied the south-western portion of Borovitsky Hill as early as the 11th century, as evidenced by a metropolitan seal from the 1090s which was unearthed by Soviet archaeologists in the area. The Vyatichi built a fortified structure (or "grad") on the hill where the Neglinnaya River flowed into the Moskva River.  Up to the 14th century, the site was known as the 'grad of Moscow'. The word "Kremlin" was first recorded in 1331 (though etymologist Max Vasmer mentions an earlier appearance in 1320). The grad was greatly extended by Prince Yuri Dolgorukiy in 1156, destroyed by the Mongols in 1237 and rebuilt in oak in 1339.

Seat of grand dukes.

Dmitri Donskoi replaced the oak walls with a strong citadel of white limestone in 1366–1368 on the basic foundations of the current walls; this fortification withstood a siege by Khan Tokhtamysh. Dmitri's son Vasily I resumed construction of churches and cloisters in the Kremlin. The newly built Cathedral of the Annunciation was painted by Theophanes the Greek, Andrei Rublev, and Prokhor in 1406. The Chudov Monastery was founded by Dmitri's tutor, Metropolitan Alexis; while his widow, Eudoxia, established the Ascension Convent in 1397.

Residence of the tsars.

Grand Prince Ivan III organised the reconstruction of the Kremlin, inviting a number of skilled architects from Renaissance Italy, including Petrus Antonius Solarius, who designed the new Kremlin wall and its towers, and Marcus Ruffus who designed the new palace for the prince. It was during his reign that three extant cathedrals of the Kremlin, the Deposition Church, and the Palace of Facets were constructed. The highest building of the city and Muscovite Russia was the Ivan the Great Bell Tower, built in 1505–08 and augmented to its present height in 1600. The Kremlin walls as they now appear were built between 1485 and 1495. Spasskie gates of the wall still bear a dedication in Latin praising Petrus Antonius Solarius for the design.  After construction of the new kremlin walls and churches was complete, the monarch decreed that no structures should be built in the immediate vicinity of the citadel. The Kremlin was separated from the walled merchant town (Kitay-gorod) by a 30-meter-wide moat, over which Saint Basil's Cathedral was constructed during the reign of Ivan the Terrible. The same tsar also renovated some of his grandfather's palaces, added a new palace and cathedral for his sons, and endowed the Trinity metochion inside the Kremlin. The metochion was administrated by the Trinity Monastery and contained the graceful tower church of St. Sergius, which was described by foreigners as one of the finest in the country.  During the Time of Troubles, the Kremlin was held by the Polish forces for two years, between 21 September 1610 and 26 October 1612. The Kremlin's liberation by the volunteer army of prince Dmitry Pozharsky and Kuzma Minin paved the way for the election of Mikhail Romanov as the new tsar. During his reign and that of his son Alexis and grandson Feodor, the eleven-domed Upper Saviour Cathedral, Armorial Gate, Terem Palace, Amusement Palace and the palace of Patriarch Nikon were built. Following the death of Alexis's son, Feodor, and the Moscow Uprising of 1682, Tsar Peter escaped with much difficulty from the Kremlin and as a result developed a dislike for it. Three decades later, Peter abandoned the residence of his forefathers for his new capital, Saint Petersburg.

Imperial period.

Although still used for coronation ceremonies, the Kremlin was abandoned and neglected until 1773, when Catherine the Great engaged Vasili Bazhenov to build her new residence there. Bazhenov produced a bombastic Neoclassical design on a heroic scale, which involved the demolition of several churches and palaces, as well as a portion of the Kremlin wall. After the preparations were over, construction was delayed due to lack of funds. Several years later the architect Matvey Kazakov supervised the reconstruction of the dismantled sections of the wall and of some structures of the Chudov Monastery, and built the spacious and luxurious Offices of the Senate, since adapted for use as the principal workplace of the President of Russia.  During the Imperial period, from the early 18th and until the late 19th century, the Kremlin walls were traditionally painted white, in accordance with fashion.  French forces occupied the Kremlin from 2 September to 11 October 1812, following the French invasion of Russia. When Napoleon retreated from Moscow, he ordered the whole Kremlin to be blown up. The Kremlin Arsenal, several portions of the Kremlin Wall and several wall towers were destroyed by explosions and the Faceted Chamber and other churches were damaged by fire. Explosions continued for three days, from 21 to 23 October 1812. However, rain damaged the fuses, and the damage was less severe than intended. Restoration works were undertaken in 1816–1819, supervised by Osip Bove. During the remainder of the reign of Alexander I, several ancient structures were renovated in a fanciful neo-Gothic style, but many others, including all the buildings of the Trinity metochion, were condemned as "disused" or "dilapidated" and were torn down.  On visiting Moscow for his coronation festivities, Czar Nicholas I was not satisfied with the Grand Palace (alias Winter Palace), which had been erected in the 1750s to the design of Francesco Rastrelli. The elaborate Baroque structure was demolished, as was the nearby church of St. John the Precursor, built by Aloisio the New in 1508 in place of the first church constructed in Moscow. The architect Konstantin Thon was commissioned to replace them with the Grand Kremlin Palace, which was to rival the Winter Palace in St. Petersburg in its dimensions and in the opulence of its interiors. The palace was constructed in 1839–1849, followed by the re-building of the Kremlin Armoury in 1851.  After 1851 the Kremlin changed little until the Russian Revolution of 1917; the only new features added during this period were the Monument to Alexander II and a stone cross marking the spot where in 1905 Grand Duke Sergei Alexandrovich of Russia was assassinated by Ivan Kalyayev. These monuments were destroyed by the Bolsheviks in 1918.

Soviet period and beyond.

The Soviet government moved from Petrograd to Moscow on 12 March 1918. Vladimir Lenin selected the Kremlin Senate as his residence. Joseph Stalin also had his personal rooms in the Kremlin. He was eager to remove all the "relics of the tsarist regime" from his headquarters. Golden eagles on the towers were replaced by shining Kremlin stars, while the wall near Lenin's Mausoleum was turned into the Kremlin Wall Necropolis.  The Chudov Monastery and Ascension Convent, with their 16th-century cathedrals, were dismantled to make room for the military school. The Little Nicholas Palace and the old Saviour Cathedral were pulled down as well. The residence of the Soviet government was closed to tourists until 1955. It was not until the Khrushchev Thaw that the Kremlin was reopened to foreign visitors. The Kremlin Museums were established in 1961 and the complex was among the first Soviet patrimonies inscribed on the World Heritage List in 1990.  Although the current director of the Kremlin Museums, Elena Gagarina (Yuri Gagarin's daughter) advocates a full-scale restoration of the destroyed cloisters, recent developments have been confined to expensive restoration of the original interiors of the Grand Kremlin Palace, which were altered during Stalin's rule.

State Kremlin Palace.

The State Kremlin Palace (alias Kremlin Palace of Congresses), was commissioned by Nikita Khrushchev as a modern arena for Communist Party meetings, and was built within the Kremlin walls 1959–1961. Externally the palace is faced with white marble and the windows are tinted and reflective. The construction of a large modern public building in a historic neighborhood generated an uproar, especially since the building replaced several heritage buildings including the old neo-classical building of the State Armory and some of the rear parts of the Great Kremlin Palace. Although this was not the first time that the Soviet government had destroyed architectural heritage (notably the Chudov Monastery and Ascension Cloisters) in the Kremlin and in the country in general, by the mid 1950s laws were in place effectively considering all pre-Soviet constructions as historical monuments and preventing their demolition, in some ways making the construction illegal. Nevertheless, the Palace was integrated into the larger complex of the Great Kremlin Palace with walkways linking it to the Patriarchal Chambers and the Terem Palace.

Buildings.

The existing Kremlin walls and towers were built by Italian masters from 1485 to 1495. The irregular triangle of the Kremlin wall encloses an area of. Its overall length is, but the height ranges from, depending on the terrain. The wall's thickness is between.  Originally there were eighteen Kremlin towers, but their number increased to twenty in the 17th century. All but three of the towers are square in plan. The highest tower is the Troitskaya, which was built up to its present height of in 1495. Most towers were originally crowned with wooden tents; the extant brick tents with strips of colored tiles go back to the 1680s.  Cathedral Square is the heart of the Kremlin. It is surrounded by six buildings, including three cathedrals. The Cathedral of the Dormition was completed in 1479 to be the main church of Moscow and where all the Tsars were crowned. The massive limestone façade, capped with its five golden cupolas, was the design of Aristotele Fioravanti. Several important metropolitans and patriarchs are buried there, including Peter and Makarii. The gilded, three-domed Cathedral of the Annunciation was completed next in 1489, only to be reconstructed to a nine-domed design a century later. On the south-east of the square is the much larger Cathedral of the Archangel Michael (1508), where almost all the Muscovite monarchs from Ivan Kalita to Ivan V of Russia are interred. (Boris Godunov was originally buried there, but was moved to the Trinity Monastery.)  There are two domestic churches of the Metropolitans and Patriarchs of Moscow, the Church of the Twelve Apostles (1653–1656) and the exquisite one-domed Church of the Deposition of the Virgin's Robe, built by Pskov artisans from 1484–1488 and featuring superb icons and frescoes from 1627 and 1644.  The other notable structure is the Ivan the Great Bell Tower on the north-east corner of the square, which is said to mark the exact centre of Moscow and resemble a burning candle. Completed in 1600, it is high. Until the Russian Revolution, it was the tallest structure in the city, as construction of buildings taller than that was forbidden. Its 21 bells would sound the alarm if any enemy was approaching. The upper part of the structure was destroyed by the French during the Napoleonic Invasion and has been rebuilt. The Tsar bell, the largest bell in the world, stands on a pedestal next to the tower.  The oldest secular structure still standing is Ivan III's Palace of Facets (1491), which holds the imperial thrones. The next oldest is the first home of the royal family, the Terem Palace. The original Terem Palace was also commissioned by Ivan III, but most of the existing palace was built in the 17th century. The Terem Palace and the Palace of Facets are linked by the Grand Kremlin Palace. This was commissioned by Nicholas I in 1838. The largest structure in the Kremlin, it cost an exorbitant sum of eleven million rubles to build and more than one billion dollars to renovate in the 1990s. It contains dazzling reception halls, a ceremonial red staircase, private apartments of the tsars, and the lower storey of the Resurrection of Lazarus church (1393), which is the oldest extant structure in the Kremlin and the whole of Moscow.  The northern corner of the Kremlin is occupied by the Arsenal, which was originally built for Peter the Great in 1701. The southwestern section of the Kremlin holds the Armoury building. Built in 1851 to a Renaissance Revival design, it is currently a museum housing Russian state Regalia and Diamond Fund.  The haloalkaliphilic methylotrophic bacterium "Methylophaga murata" was first isolated from deteriorating marble in the Kremlin.

Helipad.

In order to stop the disruptions to Moscow traffic caused by motorcades, President Vladimir Putin authorized the construction of the Kremlin helipad. The helipad was completed in May 2013. The President will now commute back and forth to the Kremlin using a Mil Mi-8 helicopter. Careful consideration was taken in choosing the location of the helipad; the location chosen is said to be of no threat to the architecture of the Kremlin.

Moscow Metro.

The nearest Moscow Metro stations to the Kremlin are: Okhotny Ryad and Biblioteka Imeni Lenina (Sokolnicheskaya Line), Teatralnaya (Zamoskvoretskaya Line), Ploshchad Revolyutsii (Arbatsko-Pokrovskaya Line), Arbatskaya (Arbatsko-Pokrovskaya Line), Alexandrovsky Sad (Filyovskaya Line), and Borovitskaya (Serpukhovsko-Timiryazevskaya Line).

The Moscow Kremlin (), or simply the Kremlin, is a fortified complex in the center of Moscow, overlooking the Moskva River to the south, Saint Basil's Cathedral and Red Square to the east, and the Alexander Garden to the west. It is the best known of the kremlins (Russian citadels) and includes five palaces, four cathedrals, and the enclosing Kremlin Wall with Kremlin towers. In addition, within this complex is the Grand Kremlin Palace that was formerly the Tsar's Moscow residence. The complex now serves as the official residence of the President of the Russian Federation and as a museum with 2,746,405 visitors in 2017.

Moskevský Kreml je středověký kreml v centru Moskvy, sloužící mimo jiné jako oficiální sídlo prezidenta Ruské federace. Kreml má velmi výrazné vnější zdi postavené z neomítaných červených pálených cihel. Jsou vysoké 5 až 19 metrů, dlouhé 2235 metrů, jejich tloušťka dosahuje 3,5 až 6,5 metru a jsou posílené dvaceti věžemi, nejvyšší – Trojická – měří 79 metrů. Půdorysem Kremlu je nepravidelný trojúhelník, jehož plocha má 277 000 m (téměř 28 hektarů). Jedná se o jeden z největších hradních komplexů na světě. Uvnitř se nachází několik z nejvýznamnějších ruských pravoslavných kostelů, například "Uspenskij sobor" (chrám Nanebevzetí Panny Marie) z 15. století, "Blagověščenskij sobor" (chrám Zvěstování Panny Marie) a "Archangelskij sobor" (chrám Archanděla Michaela) s hrobkami ruských panovníků. Kromě těchto kostelů se v Kremlu nacházejí rovněž významné paláce, například Velký kremelský palác, dokončený roku 1849, a Těremský palác se soukromými komnatami ruských carů. V několika palácích jsou vystaveny umělecké a historické poklady Ruské říše, shromážděné v průběhu celých staletí. Moskevský Kreml je největší obývaná pevnost v Evropě.


Pronunciation.

February is pronounced either as or. Many people drop the first "r", replacing it with, as if it were spelled "Febuary". This comes about by analogy with "January" (), as well as by a dissimilation effect whereby having two "r"s close to each other causes one to change for ease of pronunciation.

History.

The Roman month "Februarius" was named after the Latin term "februum", which means "purification", via the purification ritual "Februa" held on February 15 (full moon) in the old lunar Roman calendar. January and February were the last two months to be added to the Roman calendar, since the Romans originally considered winter a monthless period. They were added by Numa Pompilius about 713 BC. February remained the last month of the calendar year until the time of the decemvirs (c. 450 BC), when it became the second month. At certain times February was truncated to 23 or 24 days, and a 27-day intercalary month, Intercalaris, was occasionally inserted immediately after February to realign the year with the seasons.  February observances in Ancient Rome included Amburbium (precise date unknown), Sementivae (February 2), Februa (February 13–15), Lupercalia (February 13–15), Parentalia (February 13–22), Quirinalia (February 17), Feralia (February 21), Caristia (February 22), Terminalia (February 23), Regifugium (February 24), and Agonium Martiale (February 27). These days do not correspond to the modern Gregorian calendar.  Under the reforms that instituted the Julian calendar, Intercalaris was abolished, leap years occurred regularly every fourth year, and in leap years February gained a 29th day. Thereafter, it remained the second month of the calendar year, meaning the order that months are displayed (January, February, March,..., December) within a year-at-a-glance calendar. Even during the Middle Ages, when the numbered Anno Domini year began on March 25 or December 25, the second month was February whenever all twelve months were displayed in order. The Gregorian calendar reforms made slight changes to the system for determining which years were leap years, but also contained a 29-day February.  Historical names for February include the Old English terms Solmonath (mud month) and Kale-monath (named for cabbage) as well as Charlemagne's designation Hornung. In Finnish, the month is called "helmikuu", meaning "month of the pearl"; when snow melts on tree branches, it forms droplets, and as these freeze again, they are like pearls of ice. In Polish and Ukrainian, respectively, the month is called "luty" or "лютий" (""lyutiy""), meaning the month of ice or hard frost. In Macedonian the month is "sechko" (сечко), meaning month of cutting (wood). In Czech, it is called "únor", meaning month of submerging (of river ice).  In Slovene, February is traditionally called "svečan", related to icicles or Candlemas. This name originates from "sičan", written as "svičan" in the "New Carniolan Almanac" from 1775 and changed to its final form by Franc Metelko in his "New Almanac" from 1824. The name was also spelled "sečan", meaning "the month of cutting down of trees".  In 1848, a proposal was put forward in "Kmetijske in rokodelske novice" by the Slovene Society of Ljubljana to call this month "talnik" (related to ice melting), but it did not stick. The idea was proposed by a priest, Blaž Potočnik. Another name of February in Slovene was "vesnar", after the mythological character Vesna.

Patterns.

Having only 28 days in common years, February is the only month of the year that can pass without a single full moon. Using Coordinated Universal Time as the basis for determining the date and time of a full moon, this last happened in 2018 and will next happen in 2037. The same is true regarding a new moon: again using Coordinated Universal Time as the basis, this last happened in 2014 and will next happen in 2033.  February is also the only month of the calendar that, once every six years and twice every 11 years consecutively, either back into the past or forward into the future, has four full 7-day weeks. In countries that start their week on a Monday, it occurs as part of a common year starting on Friday, in which February 1st is a Monday and the 28th is a Sunday; this occurred in 1965, 1971, 1982, 1993, 1999 and 2010, and will occur again in 2021. In countries that start their week on a Sunday, it occurs in a common year starting on Thursday, with the next occurrence in 2026, and previous occurrences in 1987, 1998, 2009 and 2015. The pattern is broken by a skipped leap year, but no leap year has been skipped since 1900 and no others will be skipped until 2100.

Astronomy.

February meteor showers include the Alpha Centaurids (appearing in early February), the Beta Leonids, also known as the March Virginids (lasting from February 14 to April 25, peaking around March 20), the Delta Cancrids (appearing December 14 to February 14, peaking on January 17), the Omicron Centaurids (late January through February, peaking in mid-February), Theta Centaurids (January 23 – March 12, only visible in the southern hemisphere), Eta Virginids (February 24 and March 27, peaking around March 18), and Pi Virginids (February 13 and April 8, peaking between March 3 and March 9).

Astrology.

The western zodiac signs of February were Aquarius (until February 18, 2020) and Pisces (February 19, 2020 onwards). In 2021 they will shift to 17–18 due to the leap day in 2020.

Únor je podle gregoriánského kalendáře druhý měsíc v roce. Má 28 dní, v přestupném roce má 29 dní. Třikrát v historii měl únor i 30 dní. Český název měsíce vysvětlují jazykovědci tím, že se v tuto dobu při tání ledu ponořují ledové kry na řekách (únor = nořiti se).


Nature of Roman myth.

Because ritual played the central role in Roman religion that myth did for the Greeks, it is sometimes doubted that the Romans had much of a native mythology. This perception is a product of Romanticism and the classical scholarship of the 19th century, which valued Greek civilization as more "authentically creative." From the Renaissance to the 18th century, however, Roman myths were an inspiration particularly for European painting. The Roman tradition is rich in historical myths, or legends, concerning the foundation and rise of the city. These narratives focus on human actors, with only occasional intervention from deities but a pervasive sense of divinely ordered destiny. In Rome's earliest period, history and myth have a mutual and complementary relationship. As T. P. Wiseman notes: The Roman stories still "matter", as they mattered to Dante in 1300 and Shakespeare in 1600 and the founding fathers of the United States in 1776. What does it take to be a free citizen? Can a superpower still be a republic? How does well-meaning authority turn into murderous tyranny? Major sources for Roman myth include the "Aeneid" of Vergil and the first few books of Livy's history as well as Dionysius' s "Roman Antiquities". Other important sources are the "Fasti" of Ovid, a six-book poem structured by the Roman religious calendar, and the fourth book of elegies by Propertius. Scenes from Roman myth also appear in Roman wall painting, coins, and sculpture, particularly reliefs.

Founding myths.

The "Aeneid" and Livy's early history are the best extant sources for Rome's founding myths. Material from Greek heroic legend was grafted onto this native stock at an early date. The Trojan prince Aeneas was cast as husband of Lavinia, daughter of King Latinus, patronymical ancestor of the Latini, and therefore through a convoluted revisionist genealogy as forebear of Romulus and Remus. By extension, the Trojans were adopted as the mythical ancestors of the Roman people.

Other myths.

The characteristic myths of Rome are often political or moral, that is, they deal with the development of Roman government in accordance with divine law, as expressed by Roman religion, and with demonstrations of the individual's adherence to moral expectations "(mos maiorum)" or failures to do so.

Religion and myth.

Narratives of divine activity played a more important role in the system of Greek religious belief than among the Romans, for whom ritual and cult were primary. Although Roman religion did not have a basis in scriptures and exegesis, priestly literature was one of the earliest written forms of Latin prose. The books "(libri)" and commentaries "(commentarii)" of the College of Pontiffs and of the augurs contained religious procedures, prayers, and rulings and opinions on points of religious law. Although at least some of this archived material was available for consultation by the Roman senate, it was often "occultum genus litterarum", an arcane form of literature to which by definition only priests had access. Prophecies pertaining to world history and to Rome's destiny turn up fortuitously at critical junctures in history, discovered suddenly in the nebulous Sibylline books, which Tarquin the Proud (according to legend) purchased in the late 6th century BC from the Cumaean Sibyl. Some aspects of archaic Roman religion survived in the lost theological works of the 1st-century BC scholar Varro, known through other classical and Christian authors. The earliest pantheon included Janus, Vesta, and a leading so-called Archaic Triad of Jupiter, Mars, and Quirinus, whose flamens were of the highest order. According to tradition, Numa Pompilius, the Sabine second king of Rome, founded Roman religion; Numa was believed to have had as his consort and adviser a Roman goddess or nymph of fountains and of prophecy, Egeria. The Etruscan-influenced Capitoline Triad of Jupiter, Juno and Minerva later became central to official religion, replacing the Archaic Triad – an unusual example within Indo-European religion of a supreme triad formed of two female deities and only one male. The cult of Diana became established on the Aventine Hill, but the most famous Roman manifestation of this goddess may be Diana Nemorensis, owing to the attention paid to her cult by J.G. Frazer in the mythographical classic "The Golden Bough". The gods represented distinctly the practical needs of daily life, and Ancient Romans scrupulously accorded them the appropriate rites and offerings. Early Roman divinities included a host of "specialist gods" whose names were invoked in the carrying out of various specific activities. Fragments of old ritual accompanying such acts as plowing or sowing reveal that at every stage of the operation a separate deity was invoked, the name of each deity being regularly derived from the verb for the operation. Tutelary deities were particularly important in ancient Rome.  Thus, Janus and Vesta guarded the door and hearth, the Lares protected the field and house, Pales the pasture, Saturn the sowing, Ceres the growth of the grain, Pomona the fruit, and Consus and Ops the harvest. Even the majestic Jupiter, the ruler of the gods, was honored for the aid his rains might give to the farms and vineyards. In his more encompassing character he was considered, through his weapon of lightning, the director of human activity. Due to his widespread domain, the Romans regarded him as their protector in their military activities beyond the borders of their own community. Prominent in early times were the gods Mars and Quirinus, who were often identified with each other. Mars was a god of war; he was honored in March and October. Modern scholars see Quirinus as the patron of the armed community in time of peace.  The 19th-century scholar Georg Wissowa thought that the Romans distinguished two classes of gods, the "di indigetes" and the "di novensides" or "novensiles": the "indigetes" were the original gods of the Roman state, their names and nature indicated by the titles of the earliest priests and by the fixed festivals of the calendar, with 30 such gods honored by special festivals; the "novensides" were later divinities whose cults were introduced to the city in the historical period, usually at a known date and in response to a specific crisis or felt need. Arnaldo Momigliano and others, however, have argued that this distinction cannot be maintained. During the war with Hannibal, any distinction between "indigenous" and "immigrant" gods begins to fade, and the Romans embraced diverse gods from various cultures as a sign of strength and universal divine favor.

Foreign gods.

The absorption of neighboring local gods took place as the Roman state conquered neighboring territories. The Romans commonly granted the local gods of a conquered territory the same honors as the earlier gods of the Roman state religion. In addition to Castor and Pollux, the conquered settlements in Italy seem to have contributed to the Roman pantheon Diana, Minerva, Hercules, Venus, and deities of lesser rank, some of whom were Italic divinities, others originally derived from the Greek culture of Magna Graecia. In 203 BC, Rome imported the cult object embodying Cybele from Pessinus in Phrygia and welcomed its arrival with due ceremony. Both Lucretius and Catullus, poets contemporary in the mid-1st century BC, offer disapproving glimpses of Cybele's wildly ecstatic cult.  In some instances, deities of an enemy power were formally invited through the ritual of "evocatio" to take up their abode in new sanctuaries at Rome.  Communities of foreigners "(peregrini)" and former slaves "(libertini)" continued their own religious practices within the city. In this way Mithras came to Rome and his popularity within the Roman army spread his cult as far afield as Roman Britain. The important Roman deities were eventually identified with the more anthropomorphic Greek gods and goddesses, and assumed many of their attributes and myths.

Roman mythology is the body of traditional stories pertaining to ancient Rome's legendary origins and religious system, as represented in the literature and visual arts of the Romans. "Roman mythology" may also refer to the modern study of these representations, and to the subject matter as represented in the literature and art of other cultures in any period.

Římská mytologie je soubor představ o bozích a počátcích Říma, který byl vlastní starověkým Římanům. Na rozdíl od většiny jiných mytologií prakticky neobsahuje představy o přirozenosti a počátku vesmíru a člověka, ani příběhy o bozích, v důsledku řeckého vlivu však byl tento druh mýtů z velké části převzat z řecké mytologie, především v literatuře a ikonografii.


History.

Early botany.

Botany originated as herbalism, the study and use of plants for their medicinal properties. Many records of the Holocene period date early botanical knowledge as far back as 10,000 years ago. This early unrecorded knowledge of plants was discovered in ancient sites of human occupation within Tennessee, which make up much of the Cherokee land today. The early recorded history of botany includes many ancient writings and plant classifications. Examples of early botanical works have been found in ancient texts from India dating back

Early modern botany.

During the 18th century, systems of plant identification were developed comparable to dichotomous keys, where unidentified plants are placed into taxonomic groups (e.g. family, genus and species) by making a series of choices between pairs of characters. The choice and sequence of the characters may be artificial in keys designed purely for identification (diagnostic keys) or more closely related to the natural or phyletic order of the taxa in synoptic keys. By the 18th century, new plants for study were arriving in Europe in increasing numbers from newly discovered countries and the European colonies worldwide. In 1753, Carl von Linné (Carl Linnaeus) published his Species Plantarum, a hierarchical classification of plant species that remains the reference point for modern botanical nomenclature. This established a standardised binomial or two-part naming scheme where the first name represented the genus and the second identified the species within the genus. For the purposes of identification, Linnaeus's "Systema Sexuale" classified plants into 24

Late modern botany.

Building upon the gene-chromosome theory of heredity that originated with Gregor Mendel (1822–1884), August Weismann (1834–1914) proved that inheritance only takes place through gametes. No other cells can pass on inherited characters. The work of Katherine Esau (1898–1997) on plant anatomy is still a major foundation of modern botany. Her books "Plant Anatomy" and "Anatomy of Seed Plants" have been key plant structural biology texts for more than half a century.  The discipline of plant ecology was pioneered in the late 19th century by botanists such as Eugenius Warming, who produced the hypothesis that plants form communities, and his mentor and

Scope and importance.

The study of plants is vital because they underpin almost all animal life on Earth by generating a large proportion of the oxygen and food that provide humans and other organisms with aerobic respiration with the chemical energy they need to exist. Plants, algae and cyanobacteria are the major groups of organisms that carry out photosynthesis, a process that uses the energy of sunlight to convert water and carbon dioxide into sugars that can be used both as a source of chemical energy and of organic molecules that are used in the structural components of cells. As a by-product of photosynthesis, plants release oxygen into the atmosphere, a gas that is required by nearly all living things to carry out cellular respiration. In addition, they are influential in the global carbon and water cycles and plant roots bind and stabilise soils, preventing soil erosion. Plants are crucial to the future of human society as they provide food, oxygen, medicine, and products for people, as well as creating and preserving soil.  Historically, all living things were classified as either animals or plants and botany covered the study of all organisms not considered animals. Botanists examine both the internal functions and processes within plant organelles, cells, tissues, whole plants, plant populations and plant communities. At each of these levels, a botanist may be concerned with the classification (taxonomy), phylogeny and evolution, structure (anatomy and morphology), or function (physiology) of plant life.  The strictest definition of "plant" includes only the "land plants" or embryophytes, which include seed plants (gymnosperms, including the pines, and flowering plants) and the free-sporing cryptogams including ferns, clubmosses, liverworts, hornworts and mosses. Embryophytes are multicellular eukaryotes descended from an ancestor that obtained its energy from sunlight by photosynthesis. They have life cycles with alternating haploid and diploid phases. The sexual haploid phase of embryophytes, known as the gametophyte, nurtures the developing diploid embryo sporophyte within its tissues for at least part of its life, even in the seed plants, where the gametophyte itself is nurtured by its parent sporophyte. Other groups of organisms that were previously studied by botanists include bacteria (now studied in bacteriology), fungi (mycology) – including lichen-forming fungi (lichenology), non-chlorophyte algae (phycology), and viruses (virology). However, attention is still given to these groups by botanists, and fungi (including lichens) and photosynthetic protists are usually covered in introductory botany courses.  Palaeobotanists study ancient plants in the fossil record to provide information about the evolutionary history of plants. Cyanobacteria, the first oxygen-releasing photosynthetic organisms on Earth, are thought to have given rise to the ancestor of plants by entering into an endosymbiotic relationship with an early eukaryote, ultimately becoming the chloroplasts in plant cells. The new photosynthetic plants (along with their algal relatives) accelerated the rise in atmospheric oxygen started by the cyanobacteria, changing the ancient oxygen-free, reducing, atmosphere to one in which free oxygen has been abundant for more than 2 billion years.  Among the important botanical questions of the 21st century are the role of plants as primary producers in the global cycling of life's basic ingredients: energy, carbon, oxygen, nitrogen and water, and ways that our plant stewardship can help address the global environmental issues of resource management, conservation, human food security, biologically invasive organisms, carbon sequestration, climate change, and sustainability.

Plant biochemistry.

Plant biochemistry is the study of the chemical processes used by plants. Some of these processes are used in their primary metabolism like the photosynthetic Calvin cycle and crassulacean acid metabolism. Others make specialised materials like the cellulose and lignin used to build their bodies, and secondary products like resins and aroma compounds.  Plants and various other groups of photosynthetic eukaryotes collectively known as "algae" have unique organelles known as chloroplasts. Chloroplasts are thought to be descended from cyanobacteria that formed endosymbiotic relationships with ancient plant and algal ancestors. Chloroplasts and cyanobacteria contain the blue-green pigment chlorophyll "a". Chlorophyll "a" (as well as its plant and green algal-specific cousin chlorophyll "b") absorbs light in the blue-violet and orange/red parts of the spectrum while reflecting and transmitting the green light that we see as the characteristic colour of these organisms. The energy in the red and blue light that these pigments absorb is used by chloroplasts to make energy-rich carbon compounds from carbon dioxide and water by oxygenic photosynthesis, a process that generates molecular oxygen (O) as a by-product.  The light energy captured by chlorophyll "a" is initially in the form of electrons (and later a proton gradient) that's used to make molecules of ATP and NADPH which temporarily store and transport energy. Their energy is used in the light-independent reactions of the Calvin cycle by the enzyme rubisco to produce molecules of the 3-carbon sugar glyceraldehyde 3-phosphate (G3P). Glyceraldehyde 3-phosphate is the first product of photosynthesis and the raw material from which glucose and almost all other organic molecules of biological origin are synthesised. Some of the glucose is converted to starch which is stored in the chloroplast. Starch is the characteristic energy store of most land plants and algae, while inulin, a polymer of fructose is used for the same purpose in the sunflower family Asteraceae. Some of the glucose is converted to sucrose (common table sugar) for export to the rest of the plant.  Unlike in animals (which lack chloroplasts), plants and their eukaryote relatives have delegated many biochemical roles to their chloroplasts, including synthesising all their fatty acids, and most amino acids. The fatty acids that chloroplasts make are used for many things, such as providing material to build cell membranes out of and making the polymer cutin which is found in the plant cuticle that protects land plants from drying out.  Plants synthesise a number of unique polymers like the polysaccharide molecules cellulose, pectin and xyloglucan from which the land plant cell wall is constructed. Vascular land plants make lignin, a polymer used to strengthen the secondary cell walls of xylem tracheids and vessels to keep them from collapsing when a plant sucks water through them under water stress. Lignin is also used in other cell types like sclerenchyma fibres that provide structural support for a plant and is a major constituent of wood. Sporopollenin is a chemically resistant polymer found in the outer cell walls of spores and pollen of land plants responsible for the survival of early land plant spores and the pollen of seed plants in the fossil record. It is widely regarded as a marker for the start of land plant evolution during the Ordovician period. The concentration of carbon dioxide in the atmosphere today is much lower than it was when plants emerged onto land during the Ordovician and Silurian periods. Many monocots like maize and the pineapple and some dicots like the Asteraceae have since independently evolved pathways like Crassulacean acid metabolism and the carbon fixation pathway for photosynthesis which avoid the losses resulting from photorespiration in the more common carbon fixation pathway. These biochemical strategies are unique to land plants.

Plant ecology.

Plant ecology is the science of the functional relationships between plants and their habitats – the environments where they complete their life cycles. Plant ecologists study the composition of local and regional floras, their biodiversity, genetic diversity and fitness, the adaptation of plants to their environment, and their competitive or mutualistic interactions with other species. Some ecologists even rely on empirical data from indigenous people that is gathered by ethnobotanists. This information can relay a great deal of information on how the land once was thousands of years ago and how it has changed over that time. The goals of plant ecology are to understand the causes of their distribution patterns, productivity, environmental impact, evolution, and responses to environmental change.  Plants depend on certain edaphic (soil) and climatic factors in their environment but can modify these factors too. For example, they can change their environment's albedo, increase runoff interception, stabilise mineral soils and develop their organic content, and affect local temperature. Plants compete with other organisms in their ecosystem for resources. They interact with their neighbours at a variety of spatial scales in groups, populations and communities that collectively constitute vegetation. Regions with characteristic vegetation types and dominant plants as well as similar abiotic and biotic factors, climate, and geography make up biomes like tundra or tropical rainforest. Herbivores eat plants, but plants can defend themselves and some species are parasitic or even carnivorous. Other organisms form mutually beneficial relationships with plants. For example, mycorrhizal fungi and rhizobia provide plants with nutrients in exchange for food, ants are recruited by ant plants to provide protection, honey bees, bats and other animals pollinate flowers and humans and other animals act as dispersal vectors to spread spores and seeds.

Plants, climate and environmental change.

Plant responses to climate and other environmental changes can inform our understanding of how these changes affect ecosystem function and productivity. For example, plant phenology can be a useful proxy for temperature in historical climatology, and the biological impact of climate change and global warming.

Genetics.

Inheritance in plants follows the same fundamental principles of genetics as in other multicellular organisms. Gregor Mendel discovered the genetic laws of inheritance by studying inherited traits such as shape in "Pisum sativum" (peas). What Mendel learned from studying plants has had far reaching benefits outside of botany. Similarly, "jumping genes" were discovered by Barbara McClintock while she was studying maize. Nevertheless, there are some distinctive genetic differences between plants and other organisms.  Species boundaries in plants may be weaker than in animals, and cross species hybrids are often possible. A familiar example is peppermint, "Mentha" × "piperita", a sterile hybrid between "Mentha aquatica" and spearmint, "Mentha spicata". The many cultivated varieties of wheat are the result of multiple inter- and intra-specific crosses between wild species and their hybrids. Angiosperms with monoecious flowers often have self-incompatibility mechanisms that operate between the pollen and stigma so that the pollen either fails to reach the stigma or fails to germinate and produce male gametes. This is one of several methods used by plants to promote outcrossing. In many land plants the male and female gametes are produced by separate individuals. These species are said to be dioecious when referring to vascular plant sporophytes and dioicous when referring to bryophyte gametophytes.  Unlike in higher animals, where parthenogenesis is rare, asexual reproduction may occur in plants by several different mechanisms. The formation of stem tubers in potato is one example. Particularly in arctic or alpine habitats, where opportunities for fertilisation of flowers by animals are rare, plantlets or bulbs, may develop instead of flowers, replacing sexual reproduction with asexual reproduction and giving rise to clonal populations genetically identical to the parent. This is one of several types of apomixis that occur in plants. Apomixis can also happen in a seed, producing a seed that contains an embryo genetically identical to the parent.  Most sexually reproducing organisms are diploid, with paired chromosomes, but doubling of their chromosome number may occur due to errors in cytokinesis. This can occur early in development to produce an autopolyploid or partly autopolyploid organism, or during normal processes of cellular differentiation to produce some cell types that are polyploid (endopolyploidy), or during gamete formation. An allopolyploid plant may result from a hybridisation event between two different species. Both autopolyploid and allopolyploid plants can often reproduce normally, but may be unable to cross-breed successfully with the parent population because there is a mismatch in chromosome numbers. These plants that are reproductively isolated from the parent species but live within the same geographical area, may be sufficiently successful to form a new species. Some otherwise sterile plant polyploids can still reproduce vegetatively or by seed apomixis, forming clonal populations of identical individuals. Durum wheat is a fertile tetraploid allopolyploid, while bread wheat is a fertile hexaploid. The commercial banana is an example of a sterile, seedless triploid hybrid. Common dandelion is a triploid that produces viable seeds by apomictic seed.  As in other eukaryotes, the inheritance of endosymbiotic organelles like mitochondria and chloroplasts in plants is non-Mendelian. Chloroplasts are inherited through the male parent in gymnosperms but often through the female parent in flowering plants.

Plant evolution.

The chloroplasts of plants have a number of biochemical, structural and genetic similarities to cyanobacteria, (commonly but incorrectly known as "blue-green algae") and are thought to be derived from an ancient endosymbiotic relationship between an ancestral eukaryotic cell and a cyanobacterial resident.  The algae are a polyphyletic group and are placed in various divisions, some more closely related to plants than others. There are many differences between them in features such as cell wall composition, biochemistry, pigmentation, chloroplast structure and nutrient reserves. The algal division Charophyta, sister to the green algal division Chlorophyta, is considered to contain the ancestor of true plants. The Charophyte class Charophyceae and the land plant sub-kingdom Embryophyta together form the monophyletic group or clade Streptophytina.  Nonvascular land plants are embryophytes that lack the vascular tissues xylem and phloem. They include mosses, liverworts and hornworts. Pteridophytic vascular plants

Plant physiology.

Plant physiology encompasses all the internal chemical and physical activities of plants associated with life. Chemicals obtained from the air, soil and water form the basis of all plant metabolism. The energy of sunlight, captured by oxygenic photosynthesis and released by cellular respiration, is the basis of almost all life. Photoautotrophs, including all green plants, algae and cyanobacteria gather energy directly from sunlight by photosynthesis. Heterotrophs including all animals, all fungi, all completely parasitic plants, and non-photosynthetic bacteria take in organic molecules produced by photoautotrophs and respire them or use them in the construction of cells and tissues. Respiration is the oxidation of carbon compounds by breaking them down into simpler structures to release the energy they contain, essentially the opposite of photosynthesis.  Molecules are moved within plants by transport processes that operate at a variety of spatial scales. Subcellular transport of ions, electrons and molecules such as water and enzymes occurs across cell membranes. Minerals and water are transported from roots to other parts of the plant in the transpiration stream. Diffusion, osmosis, and active transport and mass flow are all different ways transport can occur. Examples of elements that plants need to transport are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. In vascular plants, these elements are extracted from the soil as soluble ions by the roots and transported throughout the plant in the xylem. Most of the elements required for plant nutrition come from the chemical breakdown of soil minerals. Sucrose produced by photosynthesis is transported from the leaves to other parts of the plant in the phloem and plant hormones are transported by a variety of processes.

Plant hormones.

Plants are not passive, but respond to external signals such as light, touch, and injury by moving or growing towards or away from the stimulus, as appropriate. Tangible evidence of touch sensitivity is the almost instantaneous collapse of leaflets of "Mimosa pudica", the insect traps of Venus flytrap and bladderworts, and the pollinia of orchids.  The hypothesis that plant growth and development is coordinated by plant hormones or plant growth regulators first emerged in the late 19th century. Darwin experimented on the movements of plant

Plant anatomy and morphology.

Plant anatomy is the study of the structure of plant cells and tissues, whereas plant morphology is the study of their external form. All plants are multicellular eukaryotes, their DNA stored in nuclei. The characteristic features of plant cells that distinguish them from those of animals and fungi include a primary cell wall composed of the polysaccharides cellulose, hemicellulose and pectin, larger vacuoles than in animal cells and the presence of plastids with unique photosynthetic and biosynthetic functions as in the chloroplasts. Other plastids contain storage products such as starch (amyloplasts) or lipids (elaioplasts). Uniquely, streptophyte cells and those of the green algal order Trentepohliales divide by construction of a phragmoplast as a template for building a cell plate late in cell division.  The bodies of vascular plants including clubmosses, ferns and seed plants (gymnosperms and angiosperms) generally have aerial and subterranean subsystems. The shoots consist of stems bearing green photosynthesising leaves and reproductive structures. The underground vascularised roots bear root hairs at their tips and generally lack chlorophyll. Non-vascular plants, the liverworts, hornworts and mosses do not produce ground-penetrating vascular roots and most of the plant participates in photosynthesis. The sporophyte generation is nonphotosynthetic in liverworts but may be able to contribute part of its energy needs by photosynthesis in mosses and hornworts.  The root system and the shoot system are interdependent – the usually nonphotosynthetic root system

Systematic botany.

Systematic botany is part of systematic biology, which is concerned with the range and diversity of organisms and their relationships, particularly as determined by their evolutionary history. It involves, or is related to, biological classification, scientific taxonomy and phylogenetics. Biological classification is the method by which botanists group organisms into categories such as genera or species. Biological classification is a form of scientific taxonomy. Modern taxonomy is rooted in the work of Carl Linnaeus, who grouped species according to shared physical characteristics. These groupings have since been revised to align better with the Darwinian principle of common descent – grouping organisms by ancestry rather than superficial characteristics. While scientists do not always agree on how to classify organisms, molecular phylogenetics, which uses DNA sequences as data, has driven many recent revisions along evolutionary lines and is likely to continue to do so. The dominant classification system is called Linnaean taxonomy. It includes ranks and binomial nomenclature. The nomenclature of botanical organisms is codified in the International Code of Nomenclature for algae, fungi, and plants (ICN) and administered by the International Botanical Congress.  Kingdom Plantae belongs to Domain Eukarya and is broken down recursively until each species is separately classified. The order is: Kingdom; Phylum (or Division); Class; Order; Family; Genus (plural "genera"); Species. The scientific name of a plant represents its genus and its species within the genus, resulting in a single worldwide name for each organism. For example, the tiger lily is "Lilium columbianum". "Lilium" is the genus, and "columbianum" the specific epithet. The combination is the name of the species. When writing the scientific name of an organism, it is proper to capitalise the first letter in the genus and put all of the specific epithet in lowercase. Additionally, the entire term is ordinarily italicised (or underlined when italics are not available).  The evolutionary relationships and heredity of a group of organisms is called its phylogeny. Phylogenetic studies attempt to discover phylogenies. The basic approach is to use similarities based on shared inheritance to determine relationships. As an example, species of "Pereskia" are trees or bushes with prominent leaves. They do not obviously resemble a typical leafless cactus such as an "Echinocactus". However, both "Pereskia" and "Echinocactus" have spines produced from areoles (highly specialised pad-like structures) suggesting that the two genera are indeed related. Judging relationships based on shared characters requires care, since plants may resemble one another through convergent evolution in which characters have arisen independently. Some euphorbias have leafless, rounded bodies adapted to water conservation similar to those of globular cacti, but characters such as the structure of their flowers make it clear that the two groups are not closely related. The cladistic method takes a systematic approach to characters, distinguishing between those that carry no information about shared evolutionary history – such as those evolved separately in different groups (homoplasies) or those left over from ancestors (plesiomorphies) – and derived characters, which have been passed down from innovations in a shared ancestor (apomorphies). Only derived characters, such as the spine-producing areoles of cacti, provide evidence for descent from a common ancestor. The results of cladistic analyses are expressed as cladograms: tree-like diagrams showing the pattern of evolutionary branching and descent.  From the 1990s onwards, the predominant approach to constructing phylogenies for living plants has been molecular phylogenetics, which uses molecular characters, particularly DNA sequences, rather than morphological characters like the presence or absence of spines and areoles. The difference is that the genetic code itself is used to decide evolutionary relationships, instead of being used indirectly via the characters it gives rise to. Clive Stace describes this as having "direct access to the genetic basis of evolution." As a simple example, prior to the use of genetic evidence, fungi were thought either to be plants or to be more closely related to plants than animals. Genetic evidence suggests that the true evolutionary relationship of multicelled organisms is as shown in the cladogram below – fungi are more closely related to animals than to plants.  In 1998, the Angiosperm Phylogeny Group published a phylogeny for flowering plants based on an analysis of DNA sequences from most families of flowering plants. As a result of this work, many questions, such as which families represent the earliest branches of angiosperms, have now been answered. Investigating how plant species are related to each other allows botanists to better understand the process of evolution in plants. Despite the study of model plants and increasing use of DNA evidence, there is ongoing work and discussion among taxonomists about how best to classify plants into various taxa. Technological developments such as computers and electron microscopes have greatly increased the level of detail studied and speed at which data can be analysed.

Botany, also called plant science(s), plant biology or phytology, is the science of plant life and a branch of biology. A botanist, plant scientist or phytologist is a scientist who specialises in this field. The term "botany" comes from the Ancient Greek word ("botanē") meaning "pasture", "grass", or "fodder"; is in turn derived from ("boskein"), "to feed" or "to graze". Traditionally, botany has also included the study of fungi and algae by mycologists and phycologists respectively, with the study of these three groups of organisms remaining within the sphere of interest of the International Botanical Congress. Nowadays, botanists (in the strict sense) study approximately 410,000 species of land plants of which some 391,000 species are vascular plants (including approximately 369,000 species of flowering plants), and approximately 20,000 are bryophytes.

Botanika neboli rostlinopis či fytologie je přírodní věda spadající do velkého okruhu věd biologických. Zkoumá tu část přírody, kterou označujeme termínem flóra, tedy rostliny a ze spíše tradičních důvodů i houby, lišejníky a většinu řas. Naproti tomu prokaryota a další mikroorganismy patří do oblasti mikrobiologie. Za zakladatele botaniky je tradičně považován řecký myslitel Theofrastos.
