The monarchies and other polities of precolonial Madagascar exerted a strong influence on each other. For this reason, in recent years it has become more interesting to trace their inter-relationship than to emphasize their autonomy. The Betsimisaraka kingdom, which flourished on Madagascar's east coast in the early eighteenth century, has generally been regarded as a polity standing rather outside the mainstream of state formation in Madagascar, not least because of the identity of its founder, the son of an English pirate. Research in European and South African archives demonstrates the close connection between the Betsimisaraka kingdom and the Sakalava kingdom of Boina.
