Answer:
The Angolan Civil War (Portuguese: Guerra Civil Angolana) 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. The war 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). The war was used as a surrogate battleground for the Cold War by rival states such as the Soviet Union, Cuba, South Africa and the United States.
The MPLA and UNITA had different roots in Angolan society and mutually incompatible leaderships, despite their shared aim of ending colonial rule. A third movement, the National Front for the Liberation of Angola (FNLA), having fought the MPLA with UNITA during the war for independence, played almost no role in the Civil War. Additionally, the Front for the Liberation of the Enclave of Cabinda (FLEC), an association of separatist militant groups, fought for the independence of the province of Cabinda from Angola With the assistance of Cuban soldiers and Soviet support, the MPLA managed to win the initial phase of conventional fighting, oust the FNLA from Luanda and become the de facto Angolan government.[38] The FNLA disintegrated, but the U.S. and South Africa-backed UNITA continued its irregular warfare against the MPLA-government from its base in the east and south of the country.
