The Portuguese government and army successfully resisted the decolonization of its overseas territories until April 1974, when a bloodless left-wing military coup in Lisbon, known as the Carnation Revolution, led the way for the independence of the overseas territories in Africa and Asia, as well as for the restoration of democracy after two years of a transitional period known as PREC (Processo Revolucionário Em Curso). This period was characterized by social turmoil and power disputes between left- and right-wing political forces. The retreat from the overseas territories and the acceptance of its independence terms by Portuguese head representatives for overseas negotiations, which would create independent states in 1975, prompted a mass exodus of Portuguese citizens from Portugal's African territories (mostly from Portuguese Angola and Mozambique).
