This article is about the Portuguese prince. For the Dutch prince sometimes known as "Henry the Navigator", see Prince Henry of the Netherlands.
The Infante Henrique, Duke of Viseu (Portuguese pronunciation: [ẽˈʁik(ɨ)]; Porto, March 4, 1394 – November 13, 1460 in Sagres) was an infante (prince) of the Portuguese House of Aviz and an important figure in the early days of the Portuguese Empire, being responsible for the beginning of the European worldwide explorations. He is known in English as Prince Henry the Navigator (Portuguese: o Navegador).
Prince Henry the Navigator was the third child of King John I of Portugal, the founder of the Aviz dynasty, and of Philippa of Lancaster, the daughter of John of Gaunt. Henry encouraged his father to conquer Ceuta (1415), the Muslim port on the North African coast across the Straits of Gibraltar from the Iberian peninsula, with profound consequences on Henry's worldview: Henry became aware of the profit possibilities in the Saharan trade routes that terminated there and became fascinated with Africa in general; he was most intrigued by the Christian legend of Prester John and the expansion of Portuguese trade.
It is a common conception that Henry gathered at his Vila on the Sagres peninsula a school of navigators and map-makers. He did employ some cartographers to help him chart the coast of Mauritania in the wake of voyages he sent there, but for the rest there was no center of navigational science or any supposed observatory in the modern sense of the word, nor was there an organized navigational center. In “Crónica da Guiné” Henry is described as a person with no luxuries, not avaricious, speaking with soft words and calm gestures, a man of many virtues that never allowed any poor person leave his presence empty handed.
