What was the purpose of the Treaty of Tordesillas established in 1494?

The Treaty of Tordesillas, established in 1494, aimed to divide newly discovered lands between Spain and Portugal. The agreement was reached to resolve disputes over newly explored territories as both nations were emerging as maritime powers during the Age of Exploration. The treaty drew an imaginary line in the Atlantic Ocean, granting Spain rights to all lands west of the line while Portugal received rights to lands to the east. This division was significant as it was intended to prevent conflict and competition between the two nations in their quest for exploration and colonization, thus fostering a degree of peace and cooperation regarding their overseas ambitions. The impact of this treaty shaped the colonial landscapes of the Americas and influenced the global balance of power for centuries to come.
