Overview

The British Empire was the largest empire in history: at its height it held 412 million people — 23 percent of the world's population — in 1913, and by 1920 covered 35.5 million km², nearly a quarter of Earth's land. Its African dimension was foundational. English involvement began with Hawkins's and Drake's slave raids off West Africa in the 1560s; the Royal African Company, chartered in 1672, carried roughly 3.5 million Africans across the Atlantic — about a third of the entire transatlantic trade — from forts such as James Island, Accra, and Bunce Island, and Britain secured the asiento contract in 1713. Yet the empire also led abolition: the slave trade was banned in 1807, Sierra Leone became a colony for freed slaves in 1808, and the Slavery Abolition Act took effect in 1833–34.

History

The 1815 settlements after Napoleon added the Cape Colony (from the Dutch), Mauritius, and the Seychelles. Through the "imperial century" of 1815–1914, Britain was the dominant power in the Scramble for Africa, pursuing the Cape-to-Cairo ambition of a continuous band of territory: Egypt (occupied 1882), the Sudan, Kenya, Uganda, Rhodesia, and the South African colonies won in the Boer Wars. West African campaigns destroyed resistant states — the Anglo-Ashanti wars culminating in the annexation of Asante in 1901, and the Benin Expedition of 1897. The First World War added German colonies (Tanganyika, South West Africa, parts of Togo and Cameroon) as mandates.

Decline and legacy

Decolonization after 1945 swept Africa: Ghana (1957) led, and Macmillan's "wind of change" speech (1960) acknowledged the tide; most African colonies were independent by the mid-1960s, though Rhodesia's white-settler UDI dragged on until Zimbabwe in 1980. The 1956 Suez Crisis had already confirmed imperial decline. The empire's successor institution, the Commonwealth, endures, and the 1997 Hong Kong handover marked its symbolic end — leaving a legacy of English language, parliamentary and legal systems, and borders that still shape Africa.
