The Angolan Civil War was a major civil conflict in the Southern African state of Angola, beginning in 1975 and continuing, with some interludes, until 2002. The war began immediately after Angola became independent from Portugal in November 1975. Prior to this, a decolonisation conflict had taken place in 1974--75, following the Angolan War of Independence. The Civil War was primarily a struggle for power between two former liberation movements, the People's Movement for the Liberation of Angola (MPLA) and the National Union for the Total Independence of Angola (UNITA). At the same time, it served as a surrogate battleground for the Cold War, due to heavy intervention by major opposing powers such as the Soviet Union and the United States.
