Antankarana
Antankarana emerged at the northern tip of Madagascar, around the limestone rocks of Ankarana. Its rulers came from a branch of the Sakalava royal line.
Andriantsirotso, who ruled from 1692 to 1710, united people around Ankarana and claimed sovereignty over the north. When Sakalava armies attacked, the inhabitants sheltered in the rocks and caves. Antankarana later paid tribute to Boina, a kingdom that arose in the eighteenth century.
