In the 1850s, land in the area was purchased by the Illinois and Wisconsin Land Company along a railroad line planned between Chicago and Janesville, Wisconsin.In 1857, the Chicago, St. Paul and Fond du Lac Railroad began running its route, stopping near the mill where a small business section had grown up, and the town of Rand was platted. In 1869, the subdivision name was changed to Des Plaines, and the village of Des Plaines was incorporated.
