    Washington County was originally organized and established in 1839 as Slaughter County; however, residents soon changed the name to Washington County in honor of George Washington.

    Washington County covers 556.75 square miles and is located in Southeast Iowa - the richest area of America's agricultural region. As of the 2010 census, the population was 21,704. The nine incorporated cities in the county are Ainsworth, Brighton, Coppock, Crawfordsville, Kalona, Riverside, Washington, Wellman, and West Chester.
