History of Macoupin County

The region was inhabited by Illinoisan Indians when the first white explorers arrived. Macoupin is an adaptation of the Miami-Illinois term for the American lotus Nelumbo lutea. None of the native Indians remain, although some descendants of the earliest European settlers claim partial ancestry. The first European contact was by French explorers in the seventeenth century, travelling southward down the major rivers. The main European settlement was from the southwest, as people moved inland from the established transportation route of the Mississippi River. Macoupin County was established on January 17, 1829. It was formed out of Greene and Madison Counties and was named after Macoupin Creek, which runs near Carlinville and meanders southwest to the Illinois River. The economy was based on subsistence agriculture, and communication was to the southwest.
