Answer:
- long-standing ethnic conflicts among Angolan tribal groups
- ideological disagreements among three liberation factions
- intervention efforts and funding by rival superpowers
Step-by-step explanation:
The Angolan civil war (1975-2002) was the longest conflict in Africa and one of the longest conditioned by the context of the Cold War. It was fought as an escalation of the Angolan War of Independence, from 1961 to 1974, which pitted several antagonistic Angolan movements, and their respective allies, but resulted immediately from the decolonization process, from 1974 to 1975, which sharpened and amplified this conflict.
The Angolan conflict faced the government of the MPLA and its allies in Cuba and SWAPO, which was fighting for the independence of Namibia, against UNITA, the FNLA, South Africa and Zaire. The former received support from advisors and Soviet material and the second advisors and material from the United States and Israel, as well as from Western mercenaries.
The contest began with the refusal of the MPLA and the FNLA to share power, dragging UNITA afterwards, but it was perpetuated by international support for each of the sides, and resumed in its second phase - after the Cuban withdrawal - by the Denial of Jonah Savimbi to accept the election results of 1992. The war ended only after the death of this, leaving at least 3500 dead, four million refugees and some 100 000 mutilated, especially by anti-personnel mines.
