In the last months of 1974 Portugal announced its intention to grant Angola independence and embarked a series of hasty efforts to negotiate a power-sharing accord, the Alvor Agreement, between rival Angolan nationalists. There were three disparate nationalist movements then active in Angola, the People's Movement for the Liberation of Angola (MPLA), the National Union for the Total Independence of Angola (UNITA), and the National Liberation Front of Angola (FNLA). The three movements had all participated in the Angolan War of Independence and shared a common goal of liberating the country from colonial rule, but also claimed unique ethnic support bases, different ideological inclinations, and their own conflicting ties to foreign parties and governments. Although each possessed vaguely socialist leanings, the MPLA was the only party which enjoyed close ties to the Soviet Union and was openly committed to Marxist policies. Its adherence to the concept of an exclusive one-party state alienated it from the FNLA and UNITA, which began portraying themselves as anti-communist and pro-Western in orientation.
