History of Alexander County

Alexander County was organized from part of Union County in 1819. It was named for William M. Alexander, a physician who practiced in the town of America, the first county seat. Alexander was elected as a representative to the state House, where he became Speaker of the Illinois House of Representatives in 1822. The county was initially developed for agriculture and settled by numerous migrants from the Upland South. The county seat was moved to Unity in 1833, then to Thebes in 1843, and finally to Cairo in 1860. America, the first county seat, is now within Pulaski County, which was formed from Alexander and Johnson counties in 1843. Settled largely by white migrants from the Upland South (who migrated from backwoods areas of Kentucky, Virginia, Tennessee, Georgia, and the Carolinas), southern Illinois had many racial attitudes of the South.
