History

Springfield's early settlement followed the Illinois Country frontier patterns after establishment in 1818, concurrent with statehood of Illinois. The city rose to prominence during the 1830s and 1840s amid westward migration and riverine trade routes tied to Mississippi River commerce and the expansion of the Illinois and Michigan Canal. Springfield became linked to Abraham Lincoln during his legal and political career, including the 1858 debates with Stephen A. Douglas and Lincoln's 1860 presidential nomination at the Republican National Convention (1860). Post-Civil War development featured railroads such as the Chicago and Alton Railroad and civic projects inspired by the City Beautiful movement. 20th-century events included involvement with World War I mobilization, industrial shifts connected to firms like S. S. Kresge Company predecessors, and mid-century expansions influenced by federal programs during the New Deal. Preservation efforts have focused on sites tied to Mary Todd Lincoln, the Lincoln Tomb, and the Old State Capitol State Historic Site.
