History of the United Kingdom
Between 1867 and 1910, the UK had granted Australia, Canada, and New Zealand "Dominion" status (near complete autonomy within the Empire). They became charter members of the British Commonwealth of Nations (known as the Commonwealth of Nations since 1949), an informal but close-knit association that succeeded the British Empire. Beginning with the independence of India and Pakistan in 1947, the remainder of the British Empire was almost completely dismantled. Today, most of Britain's former colonies belong to the Commonwealth, almost all of them as independent members. There are, however, 13 former British colonies, including Bermuda, Gibraltar, the Falkland Islands, and others, which have elected to continue rule by London and are known as British Overseas Territories.
