The South American country that has Portuguese as its national language is Brazil.
Brazil is the biggest and most populous country in South America. Its capital city is Brasilia.
Brazil was a Portuguese colony from the early 16th century until Brazilian independence in 1822. Its coasts were discovered by the explorer Pedro Alvares Cabral in 1500.
Portuguese explorers founded factories on the coasts and focused on trade and the export of wood. With time, they expanded the domains towards the west, South, and North, violating the Treaty of Tordesillas signed with the Spanish crown.
In this agreement, the Portuguese and Spanish drew an imaginary line on the planisphere that divided the areas that could be explored and conquered by each nation. East of the line corresponded to Portugal, and west, to Spain.
