<P> After World War II, Portugal was intent to hold on to its former colonies, since 1951 called overseas territories . When most former African colonies gained independence in 1957 / 1964, the Portuguese still held on . Consequently, following the Pijiguiti Massacre, the people of Cape Verde and Guinea - Bissau fought one of the longest African liberation wars . </P> <P> As with other colonies in 1972, autonomy was granted and Portuguese Cape Verde held its ony parliamentary elections in 1973, in which only those that were Portuguese citizens could vote . Out of a total population of 272,071, only 25,521 people registered to vote . A total of 20,942 people voted, giving a voter turnout of 82.1% . As the Portuguese constitution banned political parties at the time, the majority of candidates were put forward by the ruling People's National Action movement, although some civic associations were allowed to nominate candidates </P> <P> After the Carnation Revolution on April 25, 1974, Cape Verde became more autonomous but continued to have a governor from overseas, later that post would become High Commissioner . Widespread unrest forced the government to negotiate with the PAIGC, and agreements for an independent Cape Verde were on the table . Pedro Pires returned to Praia on October 13 after being exiled for over a decade . After his return, Portugal signed the 1975 Algiers Agreement . On July 5, at Praia, Portugal's Prime Minister Vasco Goncalves turned over power to National Assembly President Abilio Duarte, thus the colonial history of Cape Verde ended when Cape Verde become independent . However, there was no armed conflict in Cape Verde and ultimately independence for Cape Verde resulted from negotiation with Portugal . </P> <P> Immediately following a November 1980 coup in Guinea - Bissau (Portuguese Guinea declared independence in 1973 and was granted de jure independence in 1974), relations between the two countries became strained . Cape Verde abandoned its hope for unity with Guinea - Bissau and formed the African Party for the Independence of Cape Verde (PAICV). Problems have since been resolved, and relations between the countries are good . The PAICV and its predecessor established a one - party state and ruled Cape Verde from independence until 1990 . </P>
