County Information
The county was established in 1879 when Idaho was a territory and was named after U.S. President George Washington.
Washington County was officially created by an act of the 9th Territorial Legislature on February 20, 1879.

Washington County gave much to the agricultural and economic growth of Idaho.

William Allison, of the Upper Valley (later named Salubria) and Thomas Gray of Gray Creek, Indian Valley, were of the Ada County lower house delegation in the legislature, and were the fathers of the act creating Washington County.

The county seat and largest city is Weiser, with over half of the county's population.
