History and development

Fayette County was organized in the early years of Illinois statehood and takes its name from the Marquis de Lafayette, a symbol of support for the young United States after the Revolutionary War. Vandalia, the county seat, played a role in Illinois' early government and served as the state capital during the first decades after statehood. Over time the county developed around agriculture, commerce tied to regional transportation routes, and small-scale manufacturing.

Local historical societies and preserved sites document pioneer life, nineteenth-century civic history and the county's role in state developments. Cultural heritage is reflected in local museums, historic homes and markers that attract visitors interested in early Illinois history.
