What happened

After Ceuta, Prince Henry settled at Sagres on Portugal's southern tip and began assembling cartographers, navigators, astronomers, and shipbuilders, including both Christian and Jewish experts who drew on Arab sources of navigational and geographic knowledge. He organized and financed a string of voyages down the West African coast, searching for gold, slaves, a route around Muslim-controlled trade, and the legendary Christian king Prester John, rumored to rule somewhere near Ethiopia. Henry himself never went on an ocean voyage. Modern historians have found no evidence for the popular story that he founded a formal "navigation school" or observatory at Sagres. What he did organize was real: a sustained, financed program of exploration voyages that no other European ruler was running at the time.

Why it matters

Henry's financing turned exploration from occasional private ventures into a state-backed program with a purpose, and the captains he sent out worked their way down the African coast for four decades, past Cape Bojador in 1434 and eventually to the edge of the equator by the time he died in 1460. That continuous, funded effort is what later made Bartolomeu Dias's and Vasco da Gama's voyages possible.

How we know

The World History Encyclopedia's Henry the Navigator entry states directly that despite legend, there was no navigational school at Sagres, while listing the real team of experts Henry assembled there; EBSCO's Research Starters entry independently reaches the same correction, noting recent scholarship finds no evidence for a school, an observatory, or a systematic plan aimed at reaching India.
