Several families also moved to the, and over 100 settlers were living in Naper’s Settlement by 1832. It was believed that the Sauk Tribe would attach the area, so settlers temporarily moved to Fort Dearborn. When Fort Payne was built, the settlers returned.

In 1839, Naper’s Settlement was designated as the county seat for DuPage County. In 1857, the Village of Naperville was established and was later reincorporated as a city in 1890.
