History

Founded in 1854

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

Washington County was created by proclamation of the acting governor of Nebraska Territory from non-county area on November 23, 1854. Over the following two decades, the county exchanged land with Dodge County multiple times and gained and lost territory to Burt and Douglas counties.
