The written history of Madagascar began in the seventh century A.D., when Arabs established trading posts along the northwest coast. European contact began in the 1500s, when Portuguese sea captain Diego Dias sighted the island after his ship became separated from a fleet bound for India. In the late seventeenth century, the French established trading posts along the east coast. | The written history of Madagascar began in the seventh century A.D., when Arabs established trading posts along the northwest coast.
