Zafir Premčević participated in a war that lasted from 28 July 1914 to when?
World War I World War I (WWI or WW1), also known as the First World War, the Great War, or the War to End All Wars, was a global war originating in Europe that lasted from 28 July 1914 to 11 November 1918. More than 70 million military personnel, including 60 million Europeans, were mobilised in one of the largest wars in history. Over nine million combatants and seven million civilians died as a result of the war (including the victims of a number of genocides), a casualty rate exacerbated by the belligerents' technological and industrial sophistication, and the tactical stalemate caused by gruelling trench warfare. It was one of the deadliest conflicts in history, and paved the way for major political changes, including revolutions in many of the nations involved. Unresolved rivalries still extant at the end of the conflict contributed to the start of the Second World War only twenty-one years later.
Serbian Chetnik Organization The Serbian Revolutionary Organization (Serbian: Srpska revolucionarna organizacija/Српска револуционарна организација ) or Serbian Chetnik Organization (Српска четничка организација/Srpska četnička organizacija) was a revolutionary organization with the aim of liberation of Old Serbia (Kosovo and Macedonia) from the Ottoman Empire (in the vilayets of Kosovo, Manastir and Salonika). Its Central Committee was established in 1902, while the Serbian Committee (Српски комитет) was established in September 1903 in Belgrade, by the combined Central Boards of Belgrade, Vranje, Skopje and Bitola. Its armed wing was activated in 1904. Among the architects were members of the Saint Sava society, Army Staff and Ministry of Foreign Affairs. It operated during the Struggle for Macedonia (Борба за Македонију), a series of social, political, cultural and military conflicts in the region of Macedonia; its operations are known as Serb Action in Macedonia (Српска акција у Македонији).
