Mission San Rafael was founded by the Spanish Franciscans in Coast Miwok territory in the late fall of 1817. By that time the only Coast Miwok people still on their land were those on the Pacific Coast of the Marin Peninsula, from Point Reyes north to Bodega Bay. The Spanish authorities brought most of the Coast Miwoks who had been at Missions San Francisco and San Jose back north to form a founding population for Mission San Rafael. But some who had married Ohlone or Bay Miwok-speaking Mission Indians remained south of the Golden Gate. Over time in the 1820s Mission San Rafael became a mission for Coast Miwok and Pomo speakers. Mission San Francisco Solano, founded in 1823 in the Sonoma Valley (the easternmost traditional Coast Miwok region), came to be predominately a mission for Indians that spoke the Wappo or Patwin languages.
