Why did Portugal want to explore?

Answer 1

Portugal, like other major European nations of the Era of Discovery, wanted to explore to find unclaimed territory. These unclaimed territories, sometimes inhabited by natives, contained rich sources of untapped resources, and even some exotic resources that are valuable in trade. Portugal, France, Spain, England, Russia, Germany, Holland, and Turkey (At this time called the Ottoman Empire), were all major exploration nations during the Era of Discovery.
