The Yuma War was the name given to a series of United States military operations conducted in Southern California and what is today southwestern Arizona from 1850 to 1853. The Quechan (also known as Yuma) were the primary opponent of the United States Army, though engagements were fought between the Americans and other native groups in the region.
