Fed up with foreign wars, Portuguese officers overthrew Prime Minister Marcello Caetano on April 25, 1974. Many former colonies had the opportunity to define their own future.
Angola had been the richest of Portuguese colonies, with major production in coffee, diamonds, iron ore and oil. Of the former colonies, it had the largest white population, which numbered 320,000 of about 6.4 million. When 90% of its white population fled in 1974, Angola lost most of its skilled labor.
Three groups juggled for power. The Popular Movement for the Liberation of Angola (MPLA), headed by Agostinho Neto was the only progressive alternative. The National Front for the Liberation of Angola (NFLA), led by Holden Roberto, gained support from Zaire’s right-wing Joseph Mobutu, a conspirator in the assassination of Patrice Lumumba. Jonas Savimbi, who ran the National Union for the Total Independence of Angola (UNITA), worked hand-in-hand with South Africa’s apartheid regime.
