Hancock County

Hancock County is an administrative county in Illinois that spreads along the Mississippi River and contains several towns and rural communities. The region includes multiple municipalities, with Carthage and Warsaw serving as the main local centers.

Hancock County was established in 1825 and named in honor of an important founding figure. The region developed from a larger territory into its own separate administrative area.

Local residents participate in governance through open committee meetings at the County Board Room in Carthage, fostering community engagement.

The region is connected by several federal and state highways that provide access to its various communities. A car is the practical choice for exploring the different parts of the area.

The territory borders eight different counties across three states, making it a regional crossroads. This border position creates a connection between Illinois, Missouri, and Iowa.
