People of Nauru
Nauruans descended from Polynesian and Micronesian seafarers. Grouped in clans or tribes, early Nauruans traced their descent on the female side. They believed in a female deity, Eijebong, and a spirit land, also an island, called Buitani. Two of the 12 original tribal groups became extinct during the 20th century.
