The Coast Miwoks are the indigenous people of Marin County and southern Sonoma County in the northern San Francisco Bay Area. Their first contact with Europeans was when Sir Francis Drake made a visit in 1579, but his visit had no known lasting impact. However the arrival of the Spanish in the late 18th century their their forcing the majority of Miwoks to move into one of the missions in the area and devastated traditional life.
In 1835, the Mexican governor of California granted 80,000 acres to the Coast Miwoks, but the land was never given to them and after California became a state in 1848, it was not recognized.
In the 1990s, MAPOM's Sylvia Thalman did extensive genealogy research estblishing lines of descent between some 19th century Coast Miwoks and their 20th century descendants. This led to the federal tribal recognition in December 1999 of the Federated Coast Miwoks as the Federated Indians of Graton Rancheria.
In 2020, a group of Coast Miwok descendants formed the Coast Miwok Tribal Council of Marin, and on July 3, 2023, gained title to 26 acres of land in Nicasio, California, at the former site of the large Coast Miwok village Etcha Tamal.
