How many countries were discovered between the 13th century and the 18th century?

Between the 13th and 18th centuries, numerous territories were explored and claimed by European powers, leading to the discovery of many regions rather than distinct modern countries. Notable explorations included those by Spain and Portugal in the Americas and around Africa, as well as the Dutch, English, and French in Asia and the Americas. While exact numbers can vary based on definitions of "discovery," many territories that are now recognized as independent countries were encountered during this period, significantly altering global geography and politics.
