In 1975, Angola gained its independence from Portugal, and this resulted in a power struggle between three nationalist movements, which eventually led to a civil war. The Soviet Union, the United States, France, and Cuba supported different factions in the civil war. However, the country whose interests conflicted with those of Nigeria over Angola was the United States. The US feared that a communist government would be established in Angola if the Soviet-backed Popular Movement for the Liberation of Angola (MPLA) succeeded in taking power. The US, therefore, supported the rival National Union for the Total Independence of Angola (UNITA), which was backed by South Africa.
