What counties were exploring the world between 1400 and 1600?

Between 1400 and 1600, several European countries were actively exploring the world, most notably Spain and Portugal. Spain, under monarchs like Ferdinand and Isabella, sponsored voyages by explorers such as Christopher Columbus, who reached the Americas in 1492. Portugal, driven by advancements in navigation, explored the African coast and reached India and Brazil, with notable figures like Vasco da Gama and Ferdinand Magellan. Other countries, including England, France, and the Netherlands, began to join the age of exploration later in this period, seeking new trade routes and territories.
