In Angola, the Alvor Agreement was signed on January 15, 1975, granting Angola independence from Portugal on 11 November 1975. The Alvor Agreement formally ended the war for independence. The agreement, while signed by the MPLA, the FNLA, UNITA, and the Portuguese government, was never signed by the Front for the Liberation of the Enclave of Cabinda or the Eastern Revolt as the other parties had excluded them from the peace negotiations. The coalition government established by the Alvor Agreement soon fell apart as the various nationalist parties each attempted to seize power. Unable to broker a new compromise, in November 1975 Portugal's last African High Commissioner Rosa Coutinho hauled down his nation's flag and departed Angola.
