Article: About 5% of the Nicaraguan population are indigenous. The largest indigenous group in Nicaragua is the Miskito people. Their territory extended from Cape Camarón, Honduras, to Rio Grande, Nicaragua along the Mosquito Coast. There is a native Miskito language, but large groups speak Miskito Coast Creole, Spanish, Rama and other languages. The Creole English came about through frequent contact with the British who colonized the area. Many are Christians. Traditional Miskito society was highly structured with a defined political structure. There was a king, but he did not have total power. Instead, the power was split between himself, a governor, a general, and by the 1750s, an admiral. Historical information on kings is often obscured by the fact that many of the kings were semi-mythical. Another major group is the Mayangna (or Sumu) people, counting some 10,000 people.
