Putnam County, Rural administrative county in Illinois, United States
Putnam County spans 172 square miles across Illinois, featuring a landscape of farmlands, forests, and small towns with Hennepin as its county seat.
Established in 1825 from Fulton County territory, the county received its name from General Israel Putnam, who served during the American Revolutionary War.
The county population reflects strong German, Irish, and Italian heritage, influencing local traditions through community gatherings and agricultural practices.
