Historical Timeline

Decatur was founded in 1829. Primary governance eras include its early development as a frontier settlement, the industrial boom driven by the arrival of the railroad in 1854, and its 20th-century evolution into the "Soybean Capital of the World." The city's urban form was significantly defined by the 1923 damming of the Sangamon River to create Lake Decatur and the establishment of major industrial complexes by A.E. Staley and Caterpillar. The mid-century expansion of Archer Daniels Midland (ADM) finalized its status as a primary global food-processing node.
