History of Madagascar
Europe knew of Madagascar through Arab sources; based on them "The Travels of Marco Polo" claimed that "the inhabitants are Saracens, or followers of the law of Mohammed", without mentioning other inhabitants. Other than its size and location, everything about the island in the book describes southeastern Africa, not Madagascar. European contact began on 10 August 1500, when the Portuguese sea captain Diogo Dias sighted the island after his ship separated from a fleet going to India. The Portuguese continued trading with the islanders and named the island "São Lourenço" (Saint Lawrence). In 1666, François Caron, the director general of the newly formed French East India Company, sailed to Madagascar. The company failed to establish a colony on Madagascar but established ports on the nearby islands of Bourbon (now Réunion) and Isle de France (now Mauritius). In the late 17th century, the French established trading posts along the east coast. On Île Sainte-Marie, a small island off the northeastern coast of Madagascar, Captain Misson and his pirate crew allegedly founded the famous pirate utopia of Libertatia in the late 17th century. From about 1774 to 1824, Madagascar was a favorite haunt for pirates. Many European sailors were shipwrecked on the coasts of the island, among them Robert Drury, whose journal is one of the few written depictions of life in southern Madagascar during the 18th century. Sailors sometimes called Madagascar "Island of the Moon".
Madagascar
Upon arrival, early settlers practiced slash-and-burn agriculture to clear the coastal rainforests for cultivation. The first settlers encountered Madagascar's abundance of megafauna, including giant lemurs, elephant birds, giant fossa and the Malagasy hippopotamus, which have since become extinct because of hunting and habitat destruction. By 600 AD, groups of these early settlers had begun clearing the forests of the central highlands. Arab traders first reached the island between the 7th and 9th centuries. A wave of Bantu-speaking migrants from southeastern Africa arrived around 1000 AD. South Indian Tamil merchants arrived around 11th century. They introduced the zebu, a type of long-horned humped cattle, which they kept in large herds. Irrigated paddy fields were developed in the central highland Betsileo Kingdom and were extended with terraced paddies throughout the neighboring Kingdom of Imerina a century later. The rising intensity of land cultivation and the ever-increasing demand for zebu pasturage had largely transformed the central highlands from a forest ecosystem to grassland by the 17th century. The oral histories of the Merina people, who may have arrived in the central highlands between 600 and 1,000 years ago, describe encountering an established population they called the Vazimba. Probably the descendants of an earlier and less technologically advanced Austronesian settlement wave, the Vazimba were assimilated or expelled from the highlands by the Merina kings Andriamanelo, Ralambo and Andrianjaka in the 16th and early 17th centuries. Today, the spirits of the Vazimba are revered as "tompontany" (ancestral masters of the land) by many traditional Malagasy communities.
