At the death of Queen Victoria in 1901 the British Empire had expanded to almost one-fifth of the world land mass and one-quarter of the world population. However, from that time it decentralised. Self-governing dominions, such as Canada and Australia, were described in1926 as autonomous members of the 'British Commonwealth of Nations'. Most other colonies, beginning with India and Pakistan, were granted independence by Britain after 1945, and most of them joined the Commonwealth. Immigration from former territories in the Caribbean and the South Asian sub-continent was substantial in the 1950s and 1960s, forming the basis of the minority ethnic population in Britain today.
