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.
Indian Ocean trade
In Madagascar, merchants and slave traders from the Middle East (Shirazi Persians, Omani Arabs, Arabized Jews, accompanied by Bantus from southeast Africa) and from Asia (Gujaratis, Malays, Javanese, Bugis) were sometimes integrated within the indigenous Malagasy clans New waves of Austronesian migrants arrived in Madagascar at this time leaving behind a lasting cultural and genetic legacy.
