1975 – Angola Joins OAU Amid Independence Struggle

On May 13, 1975, Angola was granted full membership in the Organization of African Unity (OAU) ahead of its official independence from Portugal later that year. The move was symbolic and strategic, signaling Pan-African support for the anti-colonial liberation movement led by the MPLA (Popular Movement for the Liberation of Angola). The recognition came during a time of intense civil conflict, as rival factions vied for control. The OAU’s endorsement of Angola’s sovereignty added legitimacy to the decolonization process and helped pave the way for international support, particularly from non-aligned nations. Angola’s inclusion was part of a broader wave of African nations embracing self-rule and asserting regional solidarity. May 13, 1975, is remembered as a diplomatic milestone on the road to full independence for Angola and the broader decolonization of Southern Africa.
