Digging into O’Fallon, IL’s rich history


O’Fallon, Illinois is a small city located in St. Clair County. Despite its size, O’Fallon is rich in history that dates back over two centuries. There’s no better way to dive into the history of O’Fallon than to start with its name.

O’Fallon was named after Captain Benjamin O’Fallon, who was a U.S. Army officer stationed at Fort Armstrong near Rock Island, Illinois in the early 1800s. O’Fallon was a prominent figure in diplomatic relationships with Native American tribes in the area, and he played a critical role in the Black Hawk War.

In 1820, O’Fallon traveled to St. Clair County to negotiate a treaty with the native tribes. During his visit, he met a man named Nicholas Jarrot, a trader and landowner who owned a sizeable parcel of land in the area. O’Fallon mistakenly assumed that the land belonged to Jarrot’s wife, Mary. He thus named the town in honor of Mary O’Fallon.

Today, the name O’Fallon remains a testament to the area’s rich, diverse history. From its early days as a Native American settlement to its growth under French rule and its development as a part of the United States, O’Fallon has been witness to many significant events throughout history.

One of the primary reasons for O’Fallon’s significant growth in the early days was its location near the Mississippi River. The town’s proximity to the river made it an ideal location for trade and commerce, and many early settlers saw the economic potential of the area.
