History of Randolph County

Randolph County, organized in 1795, was the second county formed in what ultimately became the state of Illinois, but which was then Illinois Territory after Virginia and Pennsylvania ceded their land claims and the Continental Congress passed the Northwest Ordinance on July 13, 1787. St. Clair County to the north had been formed in 1790 after adoption of the U.S. Constitution, and named after the first Territorial Governor, General Arthur St. Clair, who before his federal appointment, had resided in Pennsylvania. Its name honored former Virginia Governor Edmund Randolph, who as Virginia's governor had ceded that state's land claims allowing the Northwest Ordinance, and later became U.S. Attorney General.
