The distinct community of the present-day Fernandeño Tataviam Band of Mission Indians (FTBMI) originated in the lineages, villages, and culture of the pre-Mission period. Mission San Fernando was established on September 8, 1797 at the village of Achoicominga and, for years following, enslaved our ancestors from the traditional villages in the geographically surrounding area, ranging from present-day Simi Valley and Malibu in the west, Cahuenga and Encino in the south, Tujunga in the east, and the present-day Tejon Ranch in the north.
Before the founding of Mission San Fernando, our ancestors in the region lived in autonomous lineages within villages. These tribal lineages, or tribelets, consisted of speakers from the Takic branch of the Uto-Aztecan language, who intermarried with individuals from other linguistic groups within the area, as well as strengthened economic, social, and cultural relations with those outside of their language group by practicing exogamy. Each lineage held territory and maintained political and economic sovereignty over its local area, but was also linked through social exchange to neighboring villages and lineages.
