Who founded a school for sailors in Portugal that advanced navigation techniques?

The correct answer is Prince Henry the Navigator because he played a crucial role in the early days of the Portuguese Empire and was pivotal in advancing maritime discovery. In the 15th century, he established a school for sailors at Sagres, where he brought together the best navigators, cartographers, and scientists of the time. This school focused on improving navigation techniques, developing more accurate maps, and enhancing ship design, especially with the creation of the caravel, which was more maneuverable and capable of long-distance travel.

Through these efforts, Prince Henry contributed significantly to the Age of Exploration, facilitating and inspiring further voyages that led to the discovery of new lands and trade routes. His commitment to learning and advancing nautical knowledge set the stage for Portugal's dominance in maritime exploration during this period.
