Portugal imported armor and munitions, fine clothes, and several manufactured products from Flanders and Italy. Wine and dried fruits from Algarve were sold in Flanders and England, salt from Setúbal and Aveiro was a profitable export to northern Europe, and leather and kermes, a scarlet dye, were also exported. On May 10, 1293, he instituted a maritime insurance fund for Portuguese traders living in the County of Flanders, which were to pay certain sums according to tonnage, accrued to them when necessary. In 1297, King Dinis of Portugal took personal interest in the development of exports and organized the export of surplus production to European countries. In 1139 the Kingdom of Portugal achieved independence from León and under the leadership of Afonso Henriques doubled its area with the Reconquista. Vasco da Gama lands in Calicut on May 20th 1498. In 1500, the Portuguese nobleman Pedro Álvares Cabral became the first European to discover Brazil. Portuguese explorations then proceeded to southeast Asia, where they reached Japan in 1542, forty-four years after their first arrival in India.

Ten years later, in 1498, Vasco da Gama led the first fleet around Africa to the Indian subcontinent, arriving in Calicut and starting a maritime route from Portugal to India. Methodical expeditions started in 1419 along West Africa's coast under the sponsorship of prince Henry the Navigator, with Bartolomeu Dias reaching the Cape of Good Hope and entering the Indian Ocean in 1488. Portuguese sailors were at the vanguard of European exploration, chronicling and mapping the coasts of Africa and Asia, then known as the East Indies, and Canada and Brazil (the West Indies), in what came to be known as the Age of Discovery.


Portuguese maritime exploration resulted in the numerous territories and maritime routes recorded by the Portuguese as a result of their intensive maritime journeys during the 15th and 16th centuries. The Cantino planisphere, made by an anonymous cartographer in 1502, shows the world as it was understood by Europeans after their great explorations at the end of the fifteenth century.
