Band of Mission Indians conveys the message that our confederacy is comprised of villages from the regional area associated with Mission San Fernando. Tribes in southern California used this term for various reasons, one of which was the association with the mission and the Mission Federation. As a result, many tribes in southern California continue to use this English term, but have their own linguistic terms to describe themselves. Like, Tataviam, many Southern California tribes have retained or reintroduced traditional linguistic terms into their official names.
