The Angolan War of Independence and the greater Portuguese Colonial War begin.

The Angolan War of Independence, known as the Armed Struggle of National Liberation in Angola, was a war of independence fought between the Angolan nationalist forces of the MPLA, UNITA and FNLA, and Portugal. It began as an uprising by Angolans against the Portuguese imposition of forced cultivation of only cotton as a commodity crop. As the resistance spread against colonial authorities, multiple factions developed that struggled for control of Portugal's overseas province of Angola. There were three nationalist movements and also a separatist movement.

The Portuguese Colonial War, also known in Portugal as the Overseas War or in the former colonies as the War of Liberation, and also known as the Angolan, Guinea-Bissau and Mozambican Wars of Independence, was a 13-year-long conflict fought between Portugal's military and the emerging nationalist movements in Portugal's African colonies between 1961 and 1974. The Portuguese regime at the time, the Estado Novo, was overthrown by a military coup in 1974, and the change in government brought the conflict to an end. The war was a decisive ideological struggle in Lusophone Africa, surrounding nations, and mainland Portugal.
