Washington was established as the seat of Idaho County from Juntil voters in the June 1875 election selected Mount Idaho over Slate Creek and Washington.

With a gold mining boom in multiple regions during the Civil War, the Idaho Territory was established in 1863. It led to the formation of the settlement, then in Washington Territory, making it one of the oldest settlements in present-day Idaho. Miners from the previous gold strikes in Pierce and Florence fanned out to the south and discovered gold in the Warren Creek area in August 1862.
