Portuguese language in Africa Angola, Mozambique, and Guinea-Bissau with autochthonous African languages (mainly Niger–Congo family languages). In Africa, the Portuguese language experiences pressure and possibly competition from French and English. Cape Verde, Guinea-Bissau and São Tomé and Príncipe are all members of La Francophonie and Mozambique is a member of the Commonwealth of Nations and has observer status at La Francophonie. Conversely, Equatorial Guinea has announced its decision to introduce Portuguese as its third official language, in addition to Spanish and French, and has made a request for membership in the CPLP. Mauritius and Senegal have also joined the CPLP as associate observer members.
Portuguese discoveries of Africa which had probably been known to Europeans since the 14th century. In 1420 Zarco and Teixeira returned with Bartolomeu Perestrelo and began Portuguese settlement of the islands. A Portuguese attempt to capture Grand Canary, one of the nearby Canary Islands, which had been partially settled by Spaniards in 1402 was unsuccessful and met with protestations from Castile. Although the exact details are uncertain, cartographic evidence suggests the Azores were probably discovered in 1427 by Portuguese ships sailing under Henry's direction, and settled in 1432, suggesting that the Portuguese were able to navigate at least from the Portuguese coast.
