The 1974 Carnation Revolution came as a blessing for independence movements in Portugal's African colonies: Angola, Mozambique and Portuguese Guinea. As had been the case in a number of sub-Saharan countries suddenly finding themselves free of the colonial yoke, the political vacuum left behind by a previously omnipresent power gave different factions the opportunity to impose their own form of rule. Angola was no different: civil war broke out in 1975 and was to last until 2002. In some ways the Angolan civil war bore similarities to the one which had taken place in neighbouring DRC. Too much was at stake for the West not to intervene in some shape or form and in July 1975 President Ford authorised the CIA to provide covert assistance to the National Liberation Front of Angola (FNLA) and the National Union for the Total Independence of Angola (UNITA).
