capital of the young state of Illinois was the small village of
Vandalia, Illinois, in the south center of the state. On the
National Road, Vandalia was initially well-situated to fulfill its governmental role. As northern Illinois opened to settlement in the 1830s, however, public pressure grew for the capital to be relocated to a location closer to the geographic center of the state. A caucus of nine Illinois lawmakers, including the young
Whig Party lawyer Abraham Lincoln, led the effort to have the capital moved to the Sangamon County village of Springfield. Their efforts were successful in 1837, when the
Illinois General Assembly passed a law creating a two-year transition period with the goal of moving the capital to Springfield in 1839. contained chambers for both houses of the General Assembly, offices for the
Governor of Illinois and other executive officials, and a chamber for the
Illinois Supreme Court. As a result of economic growth spurred by the
American Civil War and consequent
industrialization, this fifth or
Old State Capitol was, by the 1870s, too small to serve the purpose for which it had been built. Illinois built its sixth and current
State Capitol building four blocks to the southwest, and the state government turned the Old State Capitol over to Sangamon County to serve as the county
courthouse. ==Courthouse==
