The African Party of Independence of Cape Verde (Partido Africano da Independência de Cabo Verde, PAICV) is a democratic socialist political party in Cape Verde. It was formerly a Marxist–Leninist communist party and the sole legal party in the country from 1981 to 1990. Its members are nicknamed "os tambarinas" (the tamarinds) in Portuguese, and they identify themselves with the color yellow.
In 1956, its forerunner, the African Party for the Independence of Guinea and Cape Verde (PAIGC), was founded by the Cape Verdean nationalist leader Amílcar Cabral (born in Guinea-Bissau). PAIGC fought to overthrow the Portuguese Empire, unify Cape Verde and Guinea-Bissau, and use its vanguardism to advance socialist revolution.
From 1961 on, the PAIGC fought a guerrilla warfare campaign in cooperation with its fraternal party umbrella group, the CONCP, during the Portuguese Colonial War. By 1973 the PAIGC controlled Guinea-Bissau, while Portugal's own Carnation Revolution in 1974 effectively dissolved the empire, relinquishing Cape Verde within the next year.
After the wars of national liberation, the PAIGC established a socialist state within both territories under Amilcar Cabral's brother, Luís Cabral.
Following a military coup in Guinea-Bissau that ousted Cabral in November 1980, the Cape Verde portion of the party became the PAICV in January 1981; it was headed by the President of Cape Verde, Aristides Pereira. The PAICV was Cape Verde's sole legal party from 1981 until the abolition of the one-party state in 1990.
At an extraordinary party congress in February 1990, the PAICV approved the introduction of multiparty democracy. Pereira stepped down as General Secretary of PAICV in July 1990, and Prime Minister Pedro Pires replaced him in August 1990. The PAICV won 23 of the 79 National Assembly seats in the January 1991 multiparty parliamentary election, losing to the Movement for Democracy (MpD). Pereira was subsequently defeated in the February 1991 presidential election, and PAICV again fared poorly in the December 1991 local elections.
