History
Fayette County was formed in 1821 out of Bond, Clark, and Crawford counties; according to one source, the county was formed on February 14, 1812. It was named in honor of the Marquis de LaFayette, French hero of the American Revolutionary War.
In 1823, Marion County, Illinois was carved out from the southernmost part of Fayette County; this was followed by the creation of Clay, Clinton and Shelby Counties from Fayette County areas. Early Tazewell County also received acreage from Fayette County. The year 1831 saw the creation of Effingham County and the establishment of the modern Fayette County boundaries.
