Government. The boti , or clan, system, which according to oral tradition was imported from Samoa around 1400 . , remained the central focus of social and political life in Tungaru until around 1870. By the time of the establishment of the British protectorate in 1892, the traditional boti system had largely been eradicated, replaced judicially and administratively by a central government station on each island. Another major change came when the colonial administration completely reorganized the land tenure system before the 1930s, taking households that had been dispersed as hamlets in the bush and lining them up in villages along a central thoroughfare. At that time, control over village and family activities started to move to the heads of families. In 1963, the British colonial government abolished the kingship ( uea ) system that was part of the traditional political structure of the northern islands. The council of elders ( unimane ) that historically included all the male senior family heads is now responsible for overseeing village and island affairs. Local government consists of statutory island councils with elected members and limited administrative and financial powers and government-appointed administrators.
