The Treaty of Tordesillas resulted in the establishment of colonial territories between Spain and Portugal, dividing newly discovered lands outside Europe along a meridian 370 leagues west of the Cape Verde islands. Signed in 1494, the treaty aimed to resolve disputes over claims in the Americas and prevent conflict between the two powers. Spain gained rights over vast territories in the Americas, while Portugal received territories in Africa and Asia. This division laid the groundwork for future colonial expansion and shaped the cultural and political landscapes of the Spanish and Portuguese empires, influencing global history for centuries.
