About St. Clair County
St. Clair County Timeline
St. Clair County, Illinois, has a rich and diverse history that dates back to the early 18th century. The region was originally inhabited by Native American tribes, including the Cahokia and Illinois tribes, who lived along the Mississippi River. In the early 1700s, French explorers, such as Louis Joliet and Father Jacques Marquette, arrived in the area and established a fur trading post near present-day Cahokia. This marked the beginning of European settlement in St. Clair County.
In 1763, the area came under British control following the French and Indian War. However, after the American Revolutionary War, the region was ceded to the new United States as part of the Northwest Territory. St. Clair County was officially established in 1790 and named after Arthur St. Clair, a Revolutionary War officer. It was one of the first counties in the Illinois Territory and included a vast area that extended beyond the borders of present-day Illinois.
Throughout the 19th century, St. Clair County experienced significant growth and development. The county became a transportation hub with the opening of the National Road in the early 1830s, which connected the region to the eastern seaboard. The construction of the Illinois and Michigan Canal in the 1840s further enhanced transportation in the area.
St. Clair County was also a key player in the industrial revolution. Coal mining became a major industry in the county, with numerous mines opening in the 19th and early 20th centuries. The county's proximity to St. Louis, Missouri, and its growing industrialization also contributed to St. Clair County's growth.
Today, St. Clair County continues to thrive as an important economic and cultural center in Illinois. It is home to major cities and towns, including Belleville, East St. Louis, and O'Fallon.
