History

Formed in 1863 from Walla Walla County

An old deed may name a county that no longer exists, or a boundary that has since moved.

Stevens County was created by Washington Territory from Walla Walla County in 1863. It gained territory from Spokane County (original) in 1864 and from Walla Walla County in 1865, but lost area to the creation of Whitman County in 1872, Spokane County in 1879, Okanogan County in 1888, and Ferry County in 1899. When Washington became a state in 1889, Stevens County continued as a county within the new state.
