The Carnation Revolution in Lisbon, Portugal in 1974 established a military government that promptly ceased anti-independence fighting in Angola and agreed to hand over power to a coalition of three pro-independence Angolan movements. The coalition quickly broke down and the newly independent Angola broke into a state of civil war. Maintaining control over Luanda and the lucrative oil fields of the Atlantic coastline, Agostinho Neto, the leader of the MPLA, declared the independence of the Portuguese Overseas Province of Angola as the People's Republic of Angola on November 11, 1975, in accordance with the Alvor Accords. UNITA and FNLA together declared Angolan independence in Huambo. These differences reignited civil war between UNITA & FNLA and the MPLA, with the latter winning the upper hand. Agostinho Neto became the first president upon independence, and he was succeeded after his death by José Eduardo dos Santos in 1979. In 1974/76, South Africa intervened militarily in favor of FNLA and UNITA, and Zaire and the United States also heavily aided the two groups. Cuba deployed thousands of troops in 1975 to aid the MPLA against South African intervention, with the Soviet Union aiding both Cuba and the MPLA government during the war. In November 1980, the MPLA had all but pushed UNITA into the bush, and the South African forces withdrew. The United States Congress barred further U.S. military involvement in the country against the wishes of President Ronald Reagan, fearing another Vietnam-style quagmire. In 1976 the FNLA withdrew its troops to their bases in Zaire, while part of them joined the 32 Battalion formed by South Africa in order to receive anti-MPLA Angolans. At its first congress, in 1977, the MPLA adopted Marxism–Leninism as the party ideology and added Partido do Trabalho to its name. After Nito Alves's attempted coup in 1977, Neto ordered the killing of suspected followers and sympathisers of "orthodox communism" inside and outside the party. During the coup, Cuban forces stationed in Angola sided with the MPLA leadership against the coup organizers. Estimates for the number of Nito Alves followers killed by Cuban and MPLA troops in the aftermath, range from 2,000 to 70,000 dead, with some placing the death toll at 18,000 killed. After the violent internal conflict called Fractionism, it made it clear that it would follow the socialist, not the communist, model. However, it maintained close ties with the Soviet Union and the Communist bloc, establishing socialist economic policies and a one-party state. Several thousand Cuban troops remained in the country to combat UNITA fighters and bolster the regime's security. In 1990, when the Cold War ended, MPLA abandoned its Marxist–Leninist ideology and on its third congress, in December, the party declared democratic socialism to be its official ideology. The MPLA emerged victorious in Angola's 1992 general election, but eight opposition parties rejected the election as rigged. UNITA sent negotiators to the Luanda, where they were killed. As a consequence, hostilities erupted in the city, and immediately spread to other parts of the country. Tens of thousands of UNITA and FNLA sympathizers were subsequently killed nationwide by MPLA forces, in what is known as the Halloween Massacre, and the civil war resumed. The war continued until 2002, when UNITA leader Jonas Savimbi was killed. The two parties promptly agreed to a ceasefire, and a plan was laid out for UNITA to demobilize and become a political party. Over 500,000 civilians were killed during the civil war. Human rights observers have accused the MPLA of "genocidal atrocities," "systematic extermination," "war crimes" and "crimes against humanity during the civil war." Political scientist Rudolph Rummel estimated that the MPLA were responsible for between 100,000 and 200,000 deaths in democide from 1975 to 1987.
