What lands did spain lay claim to and how did the portuguese react?

The Spanish monarchs desired a straight sea way to Asia. In 1492, an Italian sea captain, Christopher Columbus, persuaded Spain to sponsor a bold plan: looking for a route to Asia by navigating west crossways the Atlantic Ocean. In October of that year, Columbus touched an island in the Caribbean. He was incorrect in his thought that he had gotten the East Indies. But his journey would open the way for European settlement of the Americas. The instant influence of Columbus's journey, though, was to upsurge pulls between Spain and Portugal. The Portuguese supposed that Columbus had certainly gotten to Asia. Portugal supposed that Columbus had appealed for Spain lands that Portuguese sailors might have get hold of first. The competition between Spain and Portugal grew edgier. In 1493, Pope Alexander VI walked in to keep harmony between the two states. So he made a dividing line, drawn north to south, through the Atlantic Ocean. All lands to the west of the line, identified as the Line of Demarcation, would be Spain's. These lands comprised most of the Americas. All lands to the east of the line would go to Portugal. Portugal protested that the line gave excessively to Spain. So it was relocated beyond west to comprise parts of modern-day Brazil for the Portuguese. In 1494, Spain and Portugal contracted the Treaty of Tordesillas, in which they decided to honor the line.
