In this struggle, the principal protagonists were the MPLA (Popular Movement for the Liberation of Angola), founded in 1956, the FNLA (National Front for the Liberation of Angola), which appeared in 1961, and UNITA (National Union for the Total Independence of Angola), founded in 1966. After many years of conflict, the nation gained its independence on 11 November 1975, after the 1974 coup d'état in Lisbon, Portugal. Portugal's new leaders began a process of democratic change at home and acceptance of the independence of its former colonies.
