Following the Round Valley Settler Massacres from 1856-1859, the Mendocino War was the genocide of the Yuki (mainly Yuki tribes) between July 1859 to January 18, 1860 by white settlers in Mendocino County, California. It was caused by settler intrusion and slave raids on native lands and subsequent native retaliation, resulting in the deaths of hundreds of natives. In 1859, a band of locally sponsored rangers led by Walter S. Jarboe, called the Eel River Rangers, raided the countryside in an effort to remove natives from settler territory and move them onto the Nome Cult Farm, an area near the Mendocino Indian Reservation. The genocide killed at least 283 Indian men and countless women and children in 23 engagements over the course of six months. They were reimbursed by the U.S. government for their campaign.
