The MPLA government of Angola and UNITA rebels sign a peace treaty ending the Angolan Civil War.

The People's Movement for the Liberation of Angola, from 1977–1990 called the People's Movement for the Liberation of Angola – Labour Party, is an Angolan social democratic political party. The MPLA fought against the Portuguese Army in the Angolan War of Independence from 1961 to 1974, and defeated the National Union for the Total Independence of Angola (UNITA) and the National Liberation Front of Angola (FNLA) in the Angolan Civil War. The party has ruled Angola since the country's independence from Portugal in 1975, being the de facto government throughout the civil war and continuing to rule afterwards.

The National Union for the Total Independence of Angola is the second-largest political party in Angola. Founded in 1966, UNITA fought alongside the People's Movement for the Liberation of Angola (MPLA) and the National Liberation Front of Angola (FNLA) in the Angolan War for Independence (1961–1975) and then against the MPLA in the ensuing civil war (1975–2002). The war was one of the most prominent Cold War proxy wars, with UNITA receiving military aid initially from the People's Republic of China from 1966 until October 1975 and later from the United States and apartheid South Africa while the MPLA received material and technical support from the Soviet Union and its allies, especially Cuba.

The Angolan Civil War was a civil war in Angola, beginning in 1975 and continuing, with interludes, until 2002. The war began immediately after Angola became independent from Portugal in November 1975. It was a power struggle between two former anti-colonial guerrilla movements, the communist People's Movement for the Liberation of Angola (MPLA) and the anti-communist National Union for the Total Independence of Angola (UNITA).
