History

Logan County was formed in 1839 and named after John A. Logan, who served in the United States House of Representatives, the United States Senate, and as a general in the American Civil War. Early settlement patterns were shaped by migrants from Kentucky, Virginia, and Ohio and by land policies such as the Preemption Act of 1841 and the Homestead Act. The county's growth accelerated with the arrival of the Illinois Central Railroad, the Illinois and Michigan Canal era influences, and the later expansion of the Chicago, Burlington and Quincy Railroad. Notable 19th-century events include visits by figures associated with Abraham Lincoln and political activity linked to the Republican Party and the Whig Party. Agricultural innovation, including practices promoted by the United States Department of Agriculture and land-grant institutions such as University of Illinois Urbana–Champaign, shaped local land use. The county endured national crises such as the Panic of 1893, participation in both World War I and World War II, and mid-20th-century shifts tied to the Great Migration and mechanization advocated by entities like John Deere.
