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
Andrianampoinimerina's son Radama I (Radama the Great) assumed the throne during a turning-point in European history that had repercussions for Madagascar. With the defeat of Napoléon in 1814/1815, the balance of power in Europe and in the European colonies shifted in Britain's favor. The British, eager to exert control over the trade routes of the Indian Ocean, had captured the islands of Réunion and Mauritius from the French in 1810. Although they returned Réunion to France, they kept Mauritius as a base for expanding the British Empire. Mauritius’s governor, to woo Madagascar from French control, recognized Radama I as King of Madagascar, a diplomatic maneuver meant to underscore the idea of the sovereignty of the island and thus to preclude claims by any European powers.
