The Southern, Central & Northern Pomo Indians were inhabiting the Mendocino Sonoma coast when trappers & settlers started arriving in this area. The Southern Pomo are called the Kashia, the Central Pomo are called the Yokiya, and the Northern Pomo are called the Bokeya. They territory ranged from about the Russian River on the south to the northern border of Mendocino county on the north and extended into Lake county on the east. Different tribes had different resources which they traded with other tribes. The coast region provided recreation and all kinds of edibles. By 1811, when 95 Russian trappers, accompanied by 40 Aleut and Kodiak Indians, arrived from Alaska and established a fur trading colony at what is now Fort Ross, many Pomos had already been forced into Spanish missions or onto White reservations. Also, during the 1820s & 1830s, the Pomos were subjected to ever increasing raids by Mexicans to secure slaves, and epidemic diseases such as smallpox and cholera. In contrast, the Pomos found the Russian traders to be friendly. The Russian trappers had found that having the local Indians on their side was to their advantage. Many of the Pomos worked for the Russians. There was also an intermingling of the two cultures, religions & languages. Some of the Pomos also married Russians. The Russian trappers only stayed until 1842. When the Russians returned to Russia some of the Pomos went with them.
During the 1840s & 1850s the large numbers of settlers and fortune seekers moved into this area. Some of the Pomo worked for them. Others were enslaved.
In 1857 the U.S. government set up a reservation called Fort Bragg for the Pomos. The Fort Bragg reservation was abandoned in 1867. At that time, the 2,000 or so Pomos living there were sent to other reservations in California. Some of the Pomos escaped and returned to their homeland only to find that others had moved in making them homeless and landless with no legal recourse. In an 1860 report, the California Legislature began by saying "For gross mismanagement and fraudulent practices the Mendocino Reservation should rank at the head of all Government failures."
A white settler named Charlie Haupt married a Pomo, bought a ranch and invited her people to live on their ranch with them. This ranch was several miles inland between Fort Ross & Stewarts Point. The Kashia Pomo lived on this ranch from 1859-1919 when they moved onto 40 acres purchased for them by the U.S. government.
In 1812 California was still a territory of Spain. California became part of Mexico in 1822.
The Gualala River was used as a boundary line by the Pomos to separate the Bokeya and Yokiya tribes, by Rafael Garcias Mexican land grant until it was canceled, by Rancho de Herman and since March 11, 1859, it has been the border between Sonoma & Mendocino counties.
