Why is Henry the Navigator considered as father of navigation and exploration?

Henry the Navigator is considered the father of navigation and exploration due to his significant contributions to the Age of Discovery in the 15th century. He established a school of navigation in Portugal, where he gathered knowledge on cartography, navigation techniques, and shipbuilding, which advanced maritime exploration. His support for expeditions along the African coast laid the groundwork for the eventual discovery of sea routes to India and the Americas. Although he did not personally explore, his influence and vision greatly propelled European exploration efforts.
