Portuguese navigators were skilled sailors and explorers during the Age of Discovery in the 15th and 16th centuries. They played a crucial role in mapping new sea routes and discovering new lands, significantly expanding European knowledge of the world. Notable figures include Prince Henry the Navigator, who sponsored many expeditions, and Vasco da Gama, who found a sea route to India. These navigators utilized advanced maritime technology, such as the caravel ship, which allowed for better maneuverability and exploration. Their voyages led to the establishment of trade routes and colonies, particularly in Africa, Asia, and Brazil, shaping global trade and cultural exchanges.
