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.
Monarchy of the United Kingdom In 1714, Queen Anne was succeeded by her second cousin, and Sophia's son, George I, Elector of Hanover, who consolidated his position by defeating Jacobite rebellions in 1715 and 1719. The new monarch was less active in government than many of his British predecessors, but retained control over his German kingdoms, with which Britain was now in personal union.[58] Power shifted towards George's ministers, especially to Sir Robert Walpole, who is often considered the first British prime minister, although the title was not then in use.[59] The next monarch, George II, witnessed the final end of the Jacobite threat in 1746, when the Catholic Stuarts were completely defeated. During the long reign of his grandson, George III, Britain's American colonies were lost, the former colonies having formed the United States of America, but British influence elsewhere in the world continued to grow, and the United Kingdom of Great Britain and Ireland was created by the Acts of Union 1800.[60]
