Why might Spain and Portugal have been willing to go to war over the issue of overseas exploration?

Answer 1

Spain and Portugal were willing to go to war over overseas exploration due to their intense rivalry in acquiring new territories and resources. Both nations sought to expand their empires and secure lucrative trade routes, which were vital for economic growth and national prestige. The competition was exacerbated by the discovery of new lands, leading to conflicts over claims and territorial boundaries, as seen in the Treaty of Tordesillas. This treaty, although intended to resolve disputes, ultimately heightened tensions as both nations aimed to maximize their influence in the New World.
