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.
History of Madagascar
In 1665, François Caron, the Director General of the newly formed French East India Company, sailed to Madagascar. The Company failed to found a colony on Madagascar but established ports on the nearby islands of Bourbon and Île-de-France (today's Réunion and Mauritius respectively). In the late 17th century, the French established trading-posts along the east coast.
