Prince Henry the Navigator, also known as Infante Dom Henrique, was a Portuguese prince who lived during the 15th century. He played a pivotal role in the Age of Discovery, a period marked by European maritime exploration and expansion.
While Prince Henry himself did not embark on voyages, his contributions to navigation, cartography, and exploration had a profound impact on the course of history.
Through his visionary leadership, he founded the Sagres School, sponsored expeditions along the African coast, and supported the development of nautical instruments and maritime infrastructure.
Prince Henry’s legacy extends beyond his own lifetime, as he inspired future explorers and set the stage for the exploration and colonization of new territories.
Accomplishments of Prince Henry the Navigator
1. Founding the Sagres School
Prince Henry established the Sagres School, also known as the School of Navigation, in Sagres, Portugal. The school was founded around 1419 and served as a center for navigational and cartographic studies.

It brought together skilled navigators, astronomers, mathematicians, and cartographers, fostering a culture of learning and innovation. The school played a crucial role in advancing maritime knowledge and techniques, making significant contributions to the Age of Discovery.
2. Promotion of exploration along the African coast
One of Prince Henry’s most notable accomplishments was his active promotion and sponsorship of maritime expeditions along the western coast of Africa.
These expeditions aimed to expand Portuguese trade routes, acquire geographical knowledge, and establish contact with new cultures.
Prince Henry believed that by sailing further south along the African coast, Portugal could bypass the Muslim-dominated land routes and gain direct access to the sources of valuable goods such as gold, spices, and other resources.
3. Development of nautical instruments
Prince Henry’s support for exploration was accompanied by his encouragement of the development and refinement of nautical instruments.
The Sagres School played a crucial role in these advancements. Navigational tools such as the astrolabe, quadrant, cross-staff, and improved compasses were refined and utilized by Portuguese navigators.
These instruments enabled more accurate celestial navigation, measurement of latitude and longitude, and better charting of routes. By enhancing navigational accuracy, these developments greatly contributed to the success of subsequent maritime expeditions and discoveries.
4. Creation of the caravel
Prince Henry the Navigator played a significant role in the development and promotion of the caravel, a type of sailing vessel. The caravel was a versatile and maneuverable ship that emerged during Prince Henry’s era.
It featured a combination of square and triangular sails, allowing it to sail efficiently both with and against the wind. The caravel’s design enabled Portuguese sailors to navigate shallow waters, withstand rough seas, and undertake long-distance voyages.
This innovation was instrumental in the exploration of the African coast and subsequent voyages to the New World, as it provided the Portuguese with a reliable and adaptable ship for their maritime endeavors.
5. Expansion of geographic knowledge
Prince Henry’s sponsorship of numerous expeditions along the African coast significantly expanded European geographic knowledge.
These explorations, carried out by skilled navigators and cartographers, involved mapping previously unknown territories and establishing trading posts. The Portuguese explorers ventured further south along the African coast, discovering and documenting new lands, peoples, and natural resources.
The information gathered during these voyages greatly contributed to the advancement of cartography, provided a basis for future explorations, and helped shape the European understanding of the world.
6. Introduction of slave trading
One of the more controversial aspects of Prince Henry the Navigator’s legacy is his role in the introduction and expansion of the African slave trade. As Portuguese explorers established trade networks along the African coast, they encountered indigenous African societies that engaged in slavery.
Prince Henry and the Portuguese saw an opportunity to exploit this existing practice for their economic gain. They began capturing and trading enslaved individuals, initially as a labor force for the sugar plantations on the Atlantic islands, and later as a commodity for the transatlantic slave trade.
While Prince Henry himself did not directly participate in slave trading, his expeditions and the subsequent Portuguese presence in Africa laid the groundwork for the devastating transatlantic slave trade that followed.
It is important to note that modern perspectives condemn the practice of slavery and acknowledge the immense suffering and human rights abuses it caused.
7. Encouragement of scientific inquiry
Prince Henry’s patronage of the Sagres School fostered a culture of scientific inquiry and research. The school attracted scholars from various disciplines, including geography, mathematics, astronomy, and navigational techniques. They conducted studies, experiments, and calculations to advance maritime knowledge.
The Sagres School became a hub for exchanging ideas and expertise, pushing the boundaries of scientific understanding in areas crucial to navigation and exploration.
Prince Henry’s support and promotion of scientific inquiry paved the way for significant advancements in navigation techniques, cartography, and astronomy.
8. Development of maritime infrastructure
Prince Henry played a pivotal role in the development of maritime infrastructure in Portugal. Recognizing the need for resources and support for Portuguese explorers and traders, he ordered the construction of shipyards, docks, and warehouses.
These infrastructural developments provided essential facilities for repairing, building, and storing ships. They also enabled the Portuguese to maintain a strong naval presence along the African coast and support their expanding trade and exploration endeavors.
9. Establishment of trade routes
Prince Henry’s explorations and maritime activities led to the establishment of Portuguese trade routes along the African coast. As Portuguese sailors ventured further south, they established trading posts, known as feitorias, in strategic locations.
These trading posts facilitated the exchange of goods, including gold, ivory, spices, and other valuable resources. They also served as bases for resupplying ships and conducting diplomatic and commercial interactions with local African rulers.
The establishment of these trade routes contributed to Portugal’s economic growth and solidified its position as a major maritime trading power.
10. Inspiration for future explorers
Prince Henry’s vision and support for exploration inspired future generations of explorers. His endeavors and achievements became legendary, capturing the imaginations of ambitious individuals seeking to discover new lands, trade routes, and riches.
Notably, the legacy of Prince Henry the Navigator inspired renowned explorers such as Vasco da Gama and Christopher Columbus. Vasco da Gama, who successfully sailed from Europe to India, followed the maritime traditions established by Prince Henry.
Columbus, although sailing under the Spanish flag, was influenced by the Portuguese explorations and aimed to reach Asia by sailing westward.
Prince Henry’s contributions to maritime exploration and navigational advancements set the stage for the Age of Discovery and the subsequent European colonization of the New World.
