The southernmost county in Illinois, Alexander county originally was part of Union County and was formally incorporated in 1819, one year after statehood was achieved. It is located at the confluence of the Ohio River and the Mississippi River and is named for William M. Alexander, an early State of Illinois politician elected as Speaker of the House in 1822.
The county seat (and southernmost city in Illinois) is Cairo and the population on July 1, 1999, was 9,919, a decrease of 707 over the 1990 census. Cairo is noted for being the home of Fort Defiance, commanded by Gen. Ulysses S. Grant during the Civil War. Its strategic geographical position remains obvious.
