Decolonisation and self-governance

After the Second World War ended, the British Empire was gradually dismantled. Most of its components have become independent countries, whether Commonwealth realms or republics, and members of the Commonwealth. There remain the 14 mainly self-governing British overseas territories which retain some political association with the United Kingdom. In April 1949, following the London Declaration, the word "British" was dropped from the title of the Commonwealth to reflect its changing nature.

Burma (Myanmar since 1989) and Aden (now part of Yemen) are the only states that were British colonies at the time of the war not to have joined the Commonwealth upon independence. Former British protectorates and mandates that did not become members of the Commonwealth are Egypt (independent in 1922), Iraq (1932), Transjordan (1946), Palestine (part of which became the State of Israel in 1948), Sudan (1956), British Somaliland (which united with the former Italian Somaliland in 1960 to form the Somali Republic), Kuwait (1961), Bahrain (1971), Oman (1971), Qatar (1971) and the United Arab Emirates (1971).

The post-war Commonwealth was given a fresh mission by Queen Elizabeth II in her Christmas Day 1953 broadcast, in which she envisioned the Commonwealth as "an entirely new conception – built on the highest qualities of the Spirit of Man: friendship, loyalty, and the desire for freedom and peace". However, the British treasury was so weak that it could not operate independently of the United States. Furthermore, the loss of defence and financial roles undermined Joseph Chamberlain's early 20th-century vision of a world empire that could combine Imperial preference, mutual defence and social growth. In addition, the United Kingdom's cosmopolitan role in world affairs became increasingly limited, especially with the losses of India and Singapore. Whilst British politicians at first hoped that the Commonwealth would preserve and project British influence, they gradually lost their enthusiasm, argues Krishnan Srinivasan. Early enthusiasm waned as British policies came under fire at Commonwealth meetings. Public opinion became troubled as immigration from non-white member states became large-scale.

The term New Commonwealth gained usage in the UK (especially in the 1960s and 1970s) to refer to recently decolonised countries, predominantly non- white and developing countries. It was often used in debates regarding immigration from these countries. The United Kingdom and the pre-1945 dominions became informally known as the Old Commonwealth, or more pointedly as the 'white Commonwealth', in reference to what had been known as the 'White Dominions'.
