The moment in context
Portugal described its colonies as overseas provinces and fought to keep them from the early 1960s. Cabral’s PAIGC built liberated zones with schools and clinics inside Guinea-Bissau, FRELIMO waged war in Mozambique, and the MPLA, FNLA and UNITA competed inside Angola. Cold War and regional patrons armed these movements, but each conflict also grew out of the particular local form of Portuguese rule and out of rivalries among the movements themselves. The decisive weakness was never really military; it was that a poor dictatorship had no democratic mechanism through which war-weariness could change policy, so the fighting simply continued.
From Portuguese Colonial War, chapter 8 of The Decolonization of Africa, 1945–1994 (AUG 1975).
