The Windrush Generation and Post-War Commonwealth Migration (1945-1971)

The British Nationality Act 1948 confirmed that all citizens of British colonies and Commonwealth countries were British subjects with the full right to live and work in Britain. Post-war economic reconstruction created massive labour shortages. The new National Health Service, London Transport, and manufacturing industries urgently needed workers. Between 1948 and 1962, approximately 500,000 Commonwealth migrants arrived, primarily from the Caribbean.

The Empire Windrush docked at Tilbury on 22 June 1948, carrying 492 Jamaican passengers — the symbolic beginning of a transformation. Caribbean migrants filled jobs in the NHS (a majority of early nurses came from the Caribbean), drove buses, and worked night shifts in factories — jobs white British workers frequently refused. They faced severe housing discrimination ("No coloureds, no Irish, no dogs" was a common sign in private rentals) and racial violence.

South Asian migration followed through the 1950s and 1960s: migrants from India (especially Punjab and Gujarat), Pakistan, and later Bangladesh came to work in Bradford's textile mills, Birmingham's foundries, and across British industry. By 1971, roughly 1.2 million people of New Commonwealth origin lived in Britain. The Race Relations Acts of 1965, 1968, and 1976 progressively outlawed racial discrimination in employment, housing, and public services.
