Luanda is the capital and largest city of Angola. It is Angola's primary port, and its major industrial, cultural and urban centre. Located on Angola's northern Atlantic coast, Luanda is Angola's administrative centre, its chief seaport, and also the capital of the Luanda Province. Luanda and its metropolitan area is the most populous Portuguese-speaking capital city in the world and the most populous Lusophone city outside Brazil, with over 8.3 million inhabitants in 2020.

The Angolan War of Independence, known as the Luta Armada de Libertação Nacional in Angola, began as an uprising against forced cultivation of cotton and evolved into a multi-faction struggle for control of Portugal's overseas province of Angola among three nationalist movements and a separatist movement. The war ended when a peaceful coup in Lisbon in April 1974 overthrew Portugal's Estado Novo dictatorship and the new regime immediately stopped all military action in the African colonies, declaring its intention to grant them independence without delay.
