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. The FTBMI is an independent nation, exercising its inherent sovereign authority over its tribal citizens and territory.

Mission San Fernando was established on September 8, 1797 at the village of Achoicominga.
