Review Questions

• How did the Treaty of Tordesillas influence territorial waters and colonial expansion for Spain and Portugal?
  • The Treaty of Tordesillas significantly influenced territorial waters by establishing clear boundaries for Spanish and Portuguese claims in the New World. By delineating a line that divided the newly discovered lands, it allowed both countries to expand their colonial territories without overlapping claims. This legal framework set a precedent for later treaties regarding territorial waters and international law, as it defined how countries could assert control over newly explored regions.
• Discuss how the Treaty of Tordesillas contributed to border disputes between emerging colonial powers in the Americas.
  • While the Treaty of Tordesillas aimed to prevent conflicts between Spain and Portugal, it inadvertently sowed seeds for future border disputes with other emerging colonial powers like England, France, and the Netherlands. These nations did not recognize the treaty's legitimacy and often encroached upon territories that Spain and Portugal claimed. This led to ongoing tensions and confrontations as these countries expanded their own colonial ambitions, ultimately resulting in numerous conflicts over territorial claims throughout the Americas.
• Evaluate the long-term consequences of the Treaty of Tordesillas on global geopolitics and indigenous populations in colonized regions.
  • The long-term consequences of the Treaty of Tordesillas on global geopolitics were profound, as it set a framework for European colonization that disregarded indigenous rights and sovereignty. The division of lands between Spain and Portugal created a legacy of exploitation and conflict for indigenous populations who were often forcibly removed or subjected to European rule. Additionally, this treaty paved the way for future imperialist expansions by defining territorial claims in a rapidly changing world, which has continued relevance in contemporary discussions about sovereignty and territorial rights.
