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
Prior to the arrival of the Europeans, certain Malagasy tribes occasionally waged wars to capture and enslave prisoners. They either sold the slaves to Arab traders or kept them on-hand as laborers. Following the arrival of European slavers, human slaves became more valuable, and the coastal tribes of Madagascar took to warring with each other to obtain prisoners for the lucrative slave-trade. Instead of spears and cutlasses, the tribesmen fought with muskets, musket-balls, and gunpowder that they obtained from the Europeans, conducting fierce and brutal wars. On account of their relationship to the pirates, the Betsimisaraka in eastern Madagascar had more firearms than anyone else. They overpowered their neighbors, the Antankarana and Tsimihety, and even raided the Comoro Islands. As the tribe on the west coast with the most connections to the slave trade, the Sakalava people also had access to guns and powder.
