Spain and Portugal divided newly discovered non-Christian territories by a north-south demarcation line in the Atlantic Ocean: lands west of the line belonged to Spain; those east belonged to Portugal. This agreement validated Portugal’s 1500 claim to Brazil, officially "discovered" by Pedro Cabral. Recognition of these territories as a distinct landmass later led European mapmakers to label the Western Hemisphere "America," honoring the Italian navigator Amerigo Vespucci.
