Who was the Portuguese prince who sponsored early exploration voyages?

The Portuguese prince who sponsored early exploration voyages was Prince Henry the Navigator. Born in 1394, Henry was a son of King John I and became one of the chief patrons of Portugal’s 15th-century maritime expansion.

Henry did not personally sail on most of the voyages associated with him. Instead, he helped organize expeditions, provided royal backing, supported ship development, and encouraged the systematic exploration of the Atlantic islands and West African coast. His interests included trade, Christian expansion, and finding routes that bypassed Muslim-controlled Saharan trade networks.

Under his patronage, Portuguese sailors gradually moved beyond Cape Bojador, which European mariners had long considered dangerously difficult to pass. Gil Eanes crossed it in 1434, opening the way for further voyages. Henry also supported the use of caravels, light and maneuverable ships suited to Atlantic exploration. The nickname “the Navigator” can be misleading: his importance was chiefly as a sponsor and organizer, not as a famous hands-on navigator.
