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
With the establishment of dominion over the greater part of the Highlands, Andrianampoinimerina became the first Merina monarch to be considered a king of Madagascar. The island continued to be ruled by a succession of Merina monarchs until the last of them, Ranavalona III, was deposed and exiled to Algeria by French forces who conquered and colonized the island in 1895.
