Concept
Portuguese colonization of the Americas (Colonização portuguesa da América) constituted territories in the Americas belonging to the Kingdom of Portugal. Portugal was the leading country in the European exploration of the world in the 15th century. The Treaty of Tordesillas in 1494 divided the Earth outside Europe into Castilian and Portuguese global territorial hemispheres for exclusive conquest and colonization. Portugal colonized parts of South America (Brazil, Colónia do Sacramento, Uruguay, Guanare, Venezuela), but also made some unsuccessful attempts to colonize North America (Newfoundland and Labrador and Nova Scotia in Canada). Based on the terms defined in the Treaty of Tordesillas, the Portuguese Crown claimed it had territorial rights in the area visited by the explorer John Cabot in 1497 and 1498 on behalf of the Crown of England. To that end, in 1499 and 1500, the Portuguese mariner João Fernandes Lavrador visited the northeast Atlantic coast and Greenland, which accounts for the appearance of "Labrador" on topographical maps of the period. Subsequently, in 1501 and 1502, the Corte-Real brothers explored and charted Greenland and what is today the Canadian province of Newfoundland and Labrador, claiming these lands as part of the Portuguese Empire. Fragmentary evidence also suggests a previous expedition in 1473 by João Vaz Corte-Real, their father, with other Europeans, to Terra Nova do Bacalhau (New Land of the Codfish) in North America. The possible voyage of 1473 and several other possible pre-Columbian expeditions to North America in the 15th century, mostly from the Azores in the case of the Portuguese (included in donation royal letters), remain matters of great controversy for scholars. Their existence is based on brief or fragmentary historical documents that are unclear concerning the destinations of voyages. In 1506, King Manuel I of Portugal created taxes for the cod fisheries in Newfoundland waters. João Álvares Fagundes and Pêro de Barcelos established fishing outposts in Newfoundland and Nova Scotia around 1521.
