The concept of family and community is of great importance to Fijian culture. Within the indigenous communities many members of the extended family will adopt particular titles and roles of direct guardians. Kinship is determined through a child's lineage to a particular spiritual leader, so that a clan is based on traditional customary ties as opposed to actual biological links. These clans, based on the spiritual leader, are known as a matangali. Within the matangali are a number of smaller collectives, known as the mbito. The descent is patrilineal, and all the status is derived from the father's side.
