when did britain become the most powerful empire
British Empire The British Empire comprised the dominions, colonies, protectorates, mandates and other territories ruled or administered by the United Kingdom and its predecessor states. It originated with the overseas possessions and trading posts established by England between the late 16th and early 18th centuries. At its height, it was the largest empire in history and, for over a century, was the foremost global power.[1] By 1913, the British Empire held sway over 412 million people, 7001230000000000000♠23% of the world population at the time,[2] and by 1920, it covered 35,500,000 km2 (13,700,000 sq mi),[3] 7001240000000000000♠24% of the Earth's total land area.[4] As a result, its political, legal, linguistic and cultural legacy is widespread. At the peak of its power, the phrase "the empire on which the sun never sets" was often used to describe the British Empire, because its expanse around the globe meant that the sun was always shining on at least one of its territories.
British Empire in World War II By the end of the war in August 1945, British Commonwealth forces were responsible for the civil and/or military administration of a number of non-Commonwealth territories, occupied during the war, including Eritrea, Libya, Madagascar, Iran, Iraq, Lebanon, Italian Somaliland, Syria, Thailand and portions of Germany, Austria and Japan. Most of these military administrations were handed over to old European colonial authorities or to new local authorities soon after the end of the hostilities. Commonwealth forces administered occupation zones in Japan, Germany and Austria until 1955. World War II confirmed that Britain was no longer the great power it had once been, and that it had been surpassed by the United States on the world stage. Canada, Australia and New Zealand moved within the orbit of the United States. The image of imperial strength in Asia had been shattered by the Japanese attacks, and British prestige there was irreversibly damaged.[33] The price for India's entry to the war had been effectively a guarantee for independence, which came within two years of the end of the war, relieving Britain of its most populous and valuable colony. The deployment of 150,000 Africans overseas from British colonies, and the stationing of white troops in Africa itself led to revised perceptions of the Empire in Africa.[34]
