A brief history of Illiopolis:
Illiopolis is located on the eastern edge of Sangamon County, Illinois. Originally the paper "City of Illiopolis" was laid out and platted in 1834 as it was voted on to be the State Capitol of Illinois. It was then considered to be the exact center of the State of Illinois. Due to "The Long Nine", including Abraham Lincoln and other politicians Illiopolis was voted out of contention on the third ballot and Springfield was chosen. The "paper city" was then vacated and not settled until the Great Northern Railroad began construction in 1854. The town was then laid out and platted as the town of Wilson in 1856 although the Post Office and Railway Station was called Illiopolis. In 1867 the name was changed to the original "City of Illiopolis". As a result of early land purchases from the government, some as early as 1828, several settlements were in the township before the Village of Wilson was founded in 1856.
