This work reflects on the decolonization of Angola and the proclamation of its independence between the 1950s and 1970s. The study examines the key incidents, such as the events of January 4, February 4 and March 15, 1961, which pressured the Portuguese government to grant independence. These events marked the beginning of the armed struggle for liberation, with a particular focus on the massacres in northern Angola. The paper also explores the transition from an anticolonial war to internal conflicts during independence and highlights that the victory was both military and political. It concludes that independence was the result of a joint effort between the three nationalist movements and the people, despite internal rivalries.Palavras-chave: Decolonization; Angola; Anticolonial War; Independence.
