African Party for the Independence of Cape Verde
After achieving independence, the PAIGC was instituted as the sole legal political party of Guinea-Bissau and Cape Verde, with Luís Cabral becoming President of Guinea-Bissau. A second set of one-party elections were held in 1976 and 1977. Although the PAIGC strove for a union between Guinea-Bissau and Cape Verde, the union finally broke down following a military coup led by João Bernardo Vieira against the Cape Verdean Cabral in November 1980. The Cape Verdean branch of PAIGC was subsequently converted into a separate party, the African Party for the Independence of Cape Verde (PAICV).
