County of rock island

History & Founding

Located in the northwestern corner of Illinois, this county boasts a rich history intertwined with the Mississippi River. Established in 1831 from parts of Mercer and Whiteside counties, it was named in honor of the Rock Island, a significant island in the Mississippi River. The island itself had been a strategic location for Native American tribes and later served as a trading post. During the Black Hawk War in 1832, the island became a crucial military encampment, and legend has it that Black Hawk himself once spent a night hidden within its limestone caves. The county played a vital role in Illinois’s westward expansion, serving as a transportation hub and agricultural center contributing to the state’s growth.

The Rock River flows through the county, adding to the network of waterways. While lacking prominent mountains, the landscape features rolling hills and fertile farmland.
