Tripartite Accord (1988) in the context of "Javier Pérez de Cuéllar"

The People's Republic of Angola (Portuguese: República Popular de Angola) was declared on 11 November 1975 by leaders of the Popular Movement for the Liberation of Angola (MPLA), at the time a Marxist–Leninist organisation, as a communist state. The Angolan War of Independence from Portugal which had begun 14 years prior in 1961 ended with the Alvor Agreement, which granted independence to Angola under a transitional government that initially included groups such as the FNLA and UNITA along with the MPLA.

Disagreements between these factions resulted in civil war, which escalated following the MPLA's unilateral declaration of a people's republic in November; it competed with the rival Democratic People's Republic of Angola (UNITA), backed by South Africa and the United States, and received aid from Cuba and the Soviet Union, to which it was aligned to in the Cold War until its dissolution in 1991. The landmark Tripartite Accord of 1988 led to the withdrawal of South African and Cuban forces from Angola, and following the Bicesse Accords Angola transitioned into a multiparty democracy that was finalised with the adoption of a new constitution in 1992 while civil war between UNITA and MPLA forces continued until 2002.
