Angolan Civil War 1975-2002: MPLA, UNITA and Foreign Armies

The Angolan Civil War was fought, with interruptions, from Angola’s independence in November 1975 until April 2002. It began as a struggle between three liberation movements for control of the former Portuguese colony and became one of the largest proxy conflicts of the Cold War, involving Cuban troops, South African forces and aid from the United States and the Soviet Union. After the Cold War it continued as a fight over power, oil and diamonds until the death of the rebel leader Jonas Savimbi.

Background

Portugal ruled Angola for centuries and resisted decolonisation longer than the other European powers. An armed struggle for independence began in 1961, fought by three rival movements with different ethnic and regional bases. Portugal’s dictatorship, the Estado Novo, sent tens of thousands of conscripts to fight colonial wars in Angola, Mozambique and Guinea-Bissau at the same time.

The MPLA (Popular Movement for the Liberation of Angola), led by Agostinho Neto, drew support from Luanda, the Mbundu people and mixed-race and urban groups, and leaned towards the Soviet bloc. The FNLA (National Front for the Liberation of Angola) of Holden Roberto was rooted among the Bakongo in the north and backed by Mobutu Sese Seko’s Zaire. UNITA (National Union for the Total Independence of Angola), founded by Jonas Savimbi in 1966, was strongest among the Ovimbundu of the central highlands.

The Carnation Revolution in Portugal in April 1974 brought a government committed to leaving Africa. Under the Alvor Agreement of January 1975, the three movements were to share a transitional government until independence on 11 November 1975. The agreement collapsed within months, and fighting broke out in Luanda.

Independence and foreign intervention

By mid-1975 the MPLA controlled Luanda. The United States covertly funded the FNLA and UNITA, and in October 1975 South African troops invaded from Namibia, which South Africa then ruled, in Operation Savannah, advancing rapidly north. Zairean troops and FNLA forces approached Luanda from the north.

In November 1975 Fidel Castro sent Cuban combat troops by air and sea. On 10 November, at Quifangondo just outside Luanda, MPLA and Cuban forces routed the FNLA. The next day Neto proclaimed the People’s Republic of Angola. In the United States, Congress passed the Clark Amendment to stop covert aid, and South African forces withdrew by March 1976. The FNLA collapsed, but UNITA retreated to the south-east and began a guerrilla war.

The Cold War phase

The MPLA became a Marxist-Leninist ruling party, supported by Soviet weapons and tens of thousands of Cuban soldiers and civilian advisers. Neto died in 1979 and was succeeded by José Eduardo dos Santos, who ruled until 2017.

South Africa saw Angola as a base for SWAPO, the movement fighting for Namibian independence, and repeatedly invaded southern Angola during the 1980s while supplying UNITA. Savimbi built a headquarters at Jamba in the far south-east. The Clark Amendment was repealed in 1985, and the Reagan administration openly armed UNITA, including with Stinger anti-aircraft missiles; Savimbi was received at the White House in January 1986.

The largest battles came in 1987–88 around Cuito Cuanavale, where Angolan, Cuban, South African and UNITA forces fought for months. Both sides claimed success. The stalemate encouraged a negotiated settlement: the New York Accords of 22 December 1988 linked the withdrawal of Cuban troops from Angola to independence for Namibia, which followed in March 1990. The last Cuban troops left in 1991.

Elections and renewed war

The Bicesse Accords of May 1991 ended the fighting and called for elections. In September 1992 dos Santos won about 49.6 per cent of the presidential vote against Savimbi’s 40.1 per cent, short of the majority needed to avoid a run-off. Savimbi rejected the results as fraudulent, and the war resumed with even greater intensity. Cities such as Huambo and Kuito were besieged and heavily shelled in 1993–94, and fighting in Luanda in late 1992 killed many UNITA supporters.

The Lusaka Protocol of November 1994 brought a fragile peace under UN supervision, but it broke down in 1998. Oil, pumped mainly offshore, funded the government’s army, while UNITA sold diamonds from areas it held. The UN imposed sanctions on UNITA’s diamond trade in 1998, and international campaigners began to speak of “blood diamonds”.

The end of the war

Government offensives from 1999 drove UNITA from its bases. On 22 February 2002 Savimbi was killed in a clash with government troops in Moxico province. On 4 April 2002 UNITA’s military leaders and the Angolan army signed the Luena Memorandum of Understanding, ending the war. UNITA disarmed and became the main opposition party.

Key people

Agostinho Neto (1922–1979), a doctor and poet, led the MPLA and became Angola’s first president.

Jonas Savimbi (1934–2002) led UNITA for more than three decades. He was admired by some Western conservatives as an anti-communist fighter and condemned by others for brutality and for rejecting election results.

José Eduardo dos Santos (1942–2022) was president from 1979 to 2017, presiding over the war and the oil boom that followed.

Holden Roberto (1923–2007) led the FNLA, which lost most of its strength after 1976.

Consequences

The war killed an estimated 500,000 people, displaced about 4 million and left Angola among the most heavily mined countries in the world. In January 1997 Diana, Princess of Wales, walked through a partly cleared minefield in Huambo, drawing global attention to the campaign that produced the Ottawa Treaty banning anti-personnel mines later that year. After 2002 high oil prices fuelled rapid reconstruction, but wealth remained highly concentrated. The war also shaped southern Africa, contributing to Namibian independence and to the regional pressures that helped end apartheid in South Africa.

Myths and facts

Myth: Cuba simply acted on Soviet orders. Research in Cuban archives, notably by the historian Piero Gleijeses, shows that Havana decided to send combat troops in November 1975 on its own initiative, and Moscow only later backed the operation with airlift support.

Myth: Cuito Cuanavale was a clear victory for one side. Cuban and Angolan accounts present it as a decisive defeat for South Africa, while South African accounts stress that their forces achieved their limited aims. Most historians see a military stalemate that pushed both sides towards negotiations.

Myth: the war was only a Cold War proxy conflict. Foreign powers fed the fighting, but its roots lay in rivalries between Angolan movements and regions, and it continued for a decade after the Cold War ended.

Why it matters

The Angolan war showed how decolonisation in Africa became entangled with the Cold War, drawing armies from the Caribbean and southern Africa into a single conflict. Like the Indonesian invasion of East Timor, it began with the hurried end of Portugal’s empire in 1975. Its long aftermath also made Angola a leading example of the link between natural resources and civil war.
