Charles S. Morehead [SEP] Introduction
He was elected to Congress in 1848 and served two terms. After his congressional tenure, he joined the Know Nothing Party and was chosen as the party's candidate for governor in 1855. The campaign was marred by anti-immigrant and anti-Catholic rhetoric that touched off the "Bloody Monday" riots in Louisville. Morehead was a delegate to the Peace Conference of 1861 and the Border States Convention that attempted to stave off the Civil War. Although he favored Kentucky's neutrality, Morehead sympathized with the South and was an open critic of the Lincoln administration. He was imprisoned for disloyalty in September 1861, although no formal charges were ever brought against him.
