Rivera, writing in 1742 reported that the ship that was wrecked in 1650 "according to tradition" and that it was owned by "Lorenzo Gramalxo" (probably Lorenzo Gramajo, a prominent Portuguese merchant of Cartagena). Rise to Dominance This group of mixed ancestry were usually called Mosquitos Zambos by the Spanish, while the others living more on the southern region (in modern Nicaragua) have been dubbed Tawira Miskito (Straight-haired Miskito) by modern scholars such as Karl Offen. Over the course of the eighteenth century, the Miskito Sambu became dominant, and the office of king was in Sambu hands from the first decade of the century onward. There are a number of later stories which recount the same sequence of events, though often with different details, and different possible dates. It is possible that these accounts are of separate shipwrecks, or that the same wreck was elaborated in later accounts through oral tradition. The Miskito Sambu were aggressive, an early report of 1699 has them waging near constant war with their neighboring indigenous groups. The Spanish reported many raids directed against their holdings beginning in 1699 and continuing through most of the 18th century. The raids often carried off slaves, for use at home or for sale to English traders from Jamaica, who sent them to the island to work. The English also supplied the Miskito Sambu with muskets and military training to assist in these raids. Raiding reached as far south as modern Costa Rica and as far north as the Yucatán. According to the French buccaneer Raveneau de Lussan, who visited in 1688, the Sambu settled largely in the valley of the Wanks River (modern Rio Coco), and the report of the buccaneer M. W. in 1699, their settlements were concentrated in that river, and somewhat to the west along the coast of modern-day Honduras almost as far as Trujillo. By the early eighteenth century, the leader of the Sambu group had the Miskito title General in the chieftaincy system of the Mosquito Coast. At some point in the early eighteenth century, however, the Sambu took over the premier title of King, and the palace that was occupied by a Tawira king, Jeremy, in 1699 was now occupied by a "mulatto", also named Jeremy, in 1711. From that point on, the Sambu held the kingship. The emergence of the Miskito Sambu gradually split the larger Miskito people in two; be that
