Portuguese Trained Columbus

"In the last decade of the fifteenth century, Christopher Columbus set out on a westerly course across the Atlantic Ocean searching for an alternative route to the Indies but inadvertently "discovered" a new continent. Although neither Portuguese-born nor sponsored, Columbus was Portuguese trained. He went to Lisbon in 1476 and remained there for several years, seeking the support of the Portuguese king and gathering nautical and geographic intelligence from the returning sailors. He married a Portuguese woman; obtained navigation charts and related information from his father-in-law, Bartholomew Perestrelo, who was the governor of the island of Porto Santo in Madeira; and was employed by João II as a navigator."
