Yakima is a city in the Yakima Valley, part of the Columbia River Plateau region of Washington State. It is the county seat of Yakima County.
The Yakama people were the first known inhabitants of the Yakima area, inhabiting the Yakima Valley. In 1805, the Lewis and Clark Expedition came to the area and discovered abundant wildlife and rich soil, prompting the settlement of homesteaders. A Catholic Mission was established in Ahtanum, southwest of present-day Yakima, in 1847. The arrival of settlers and their conflicts with the natives resulted in the Yakima War. The U.S. Army established Fort Simcoe in 1856 near present-day White Swan as a response to the uprising. The Yakamas were defeated and forced to relocate to the Yakama Indian Reservation. Yakima County was created in 1865. When bypassed by the Northern Pacific Railroad in December 1884, over 100 buildings were moved with rollers and horse teams to the nearby site of the depot. The new city was dubbed North Yakima and was officially incorporated and named the county seat on January 27, 1886. The name was changed to Yakima in 1918. Union Gap was the new name given to the original site of Yakima.
