Edwardsville, named for territorial governor Ninian Edwards, began life as a frontier fort and gateway to settlers. It became the seat of law and government of Madison County, which at that time encompassed much of the Illinois Territory. The town was incorporated shortly after Illinois became a state in 1818. In 1890, industrialist N. O. Nelson began a manufacturing complex and established the model town of Leclaire Village. Edwardsville grew rapidly through the late 1800s and early 1900s. Main Street became a bustling business district while elegant mansions were constructed on St. Louis Street. Take a nostalgic look at Edwardsville 100 years ago with a stroll down Main Street, a walk through City Park, or a glimpse of the weeklong Madison County Centennial festivities.
