Did Prince Henry have the greatest influence on sea route?

Prince Henry the Navigator, while not a sailor himself, significantly influenced the development of sea routes during the Age of Exploration through his support of maritime research and navigation. He established a school for navigation in Portugal, which advanced cartography, navigation techniques, and shipbuilding. His efforts facilitated the exploration of the West African coast, leading to new trade routes and the eventual discovery of sea passages to India and the Americas. Although he was not the sole figure in shaping maritime exploration, his contributions laid the groundwork for future explorers.
