History

Formed in 1852 from Lane County

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

Douglas County was established when Oregon Territory created it from a small part of Lane County in 1852. In 1859, Douglas became an Oregon county when the state was admitted to the Union and Oregon Territory was eliminated. Over subsequent decades, the county gained territory from Umpqua and Coos, lost land to the creation of Lake County in 1874, and exchanged boundaries with neighboring counties.
