What did the Treaty of Tordesillas establish?

The Treaty of Tordesillas, signed in 1494, established a line of demarcation that divided newly discovered lands between the Spanish and Portuguese empires. This agreement aimed to resolve conflicts over newly explored territories in the Americas and other regions, following Christopher Columbus's voyages. By delineating specific areas for Spain and Portugal, it sought to prevent disputes over colonial expansion and resource competition. The treaty was essential in shaping the colonial landscape of South America, as it essentially granted Portugal control over Brazil while Spain received territories to the west. The significance of this treaty lies in its impact on the age of exploration, colonial empires, and international relations during that period.
