European exploration of Africa
One of the ships under command of Diogo Dias arrived at a coast that was not in East Africa. Two years later, a chart already showed an elongated island east of Africa that bore the name Madagascar. But only a century later, between 1613 and 1619, did the Portuguese explore the island in detail. They signed treaties with local chieftains and sent the first missionaries, who found it impossible to make locals believe in Hell, and were eventually expelled.

In 1500, when leading a second Portuguese Armada of 13 ships to India, Pedro Álvares Cabral discovers and explores Brazil, claiming it for Portugal. In the same year, Diogo Dias, as one of the Captains of the fleet to India of Pedro Álvares Cabral, is separated from the main fleet by a storm while crossing the Cape of Good Hope, and becomes the first European to reach Madagascar.
