Located on the Waukarusa creek, Mount Carroll began life as a mill town around 1841. In 1843, a referendum moved the county seat from nearby Savanna to Mount Carroll. The town was incorporated in 1855 and became a city in 1867; the first mayor was Nathaniel Halderman, a prominent local businessman and co-founder of the mill.
Shimer College was established in Mt. Carroll in 1853, but mounting debts forced a move to Waukegan, Illinois in 1979. The campus now is home to several organizations, most notably the Campbell Center for Historic Preservation Studies.
