The Amah Mutsun Tribal Band of Ohlone/Costanoan Indians, California currently has an enrolled membership of over 500 BIA documented Indians. These are the Previously Recognized Tribal group listed by the Indian Service Bureau (now know as the Bureau of Indian Affairs) as the “San Juan Band.” All lineages now comprising the “Amah Mutsun Tribal Band” are the direct descendents of the aboriginal tribal groups whose villages and territories fell under the sphere of influence of Missions San Juan Bautista and Santa Cruz during the late 18th, 19th and early 20th centuries.

As a result of the Congressional Appropriation Acts of 1906 and 1908 our tribe came under the jurisdiction of the Indian Service Bureau (BIA), and the Reno and Sacramento Indian Agencies until 1927. Our Tribe was never terminated by any Act or intent of the Congress, however, we remained a landless Tribe since our Federally Acknowledged status began in 1906. As a result of the Congressional California Indian Jurisdictional Act of 1928, both living members and direct ancestors enrolled with the BIA between 1930 and 1932. Our members also enrolled between 1948 to 1955 and during the third enrollment period between 1968 to 1970.
