History

Colusa County is one of the original counties of California, created in 1850 at the time of statehood. Parts of the county’s territory were given to Tehama County in 1856 and to Glenn County in 1891.

The county was named after the 1844 Rancho Colus Mexican land grant to John Bidwell. The name of the county in the original state legislative act of 1850 was spelled Colusi, and often in newspapers was spelled Coluse. The word is derived from the name of a Patwin village known as Ko’-roo or Korusi located on the west side of the Sacramento River on the site of the present-day city of Colusa. The name was established as Colusa by 1855.

Early history

Present-day Colusa County was originally home to the Patwin band of the Wintun people, whose territory included areas along the Sacramento River as well as lands extending west towards Lake County, bounded in the north by the sources of Stony Creek near Stonyford and in the south by Putah Creek.

Linguistically, the Patwin people in the Colusa area spoke two dialects of the Southern Wintuan language. River Patwin was spoken in villages along the Sacramento River, including at Korusi, site of the present city of Colusa. Hill Patwin was spoken in the plains and foothills to the west.

European settlement

Present-day Colusa County was included as part of three Mexican land grants: John Bidwell’s smaller 1845 Rancho Colus grant, which included the modern city of Colusa; the larger 1844 Rancho Jimeno grant, which surrounded the Colus grant; and the 1844 Larkin’s Children grant, located upriver from Colusa near the present town of Princeton, California.
