Monroe County was formed on January 28, 1813 from portions of Belmont, Guernsey and Washington counties. It was named after James Monroe, the U.S. Secretary of State when the county was formed, and later fifth President of the United States.  When organized, the county's eastern border was with the state of Virginia. This portion of the state seceded from Virginia during the American Civil War, being admitted to the Union as the state of West Virginia. The largely rural county reached its peak of population in the 19th century, before urbanization drew people into and near cities for work and other opportunities. It is still a center of Amish population and farms.
According to the U.S. Census Bureau, the county has a total area of 457 square miles (1,180 km2), of which 456 square miles (1,180 km2) is land and 1.7 square miles (4.4 km2) (0.4%) is water.  It is bordered by the Ohio River to the east. The terrain is hilly in this area, with waterways cutting through some hills of the Appalachian Plateau, which extends from Lake Erie to the Ohio River, which flows southwest to the south of this county.
