The captivating Jersey County lies Northeast of where the great Mississippi and Illinois Rivers meet. The former home of the Kickapoo, Menomini, Potawatomi, and Illini Indians was first discovered by the Europeans, Father Marquette and Louis Jolliet, in 1673. They discovered an area rich in foliage and full of wild game, rivers abundant with a pleasing variety of fish, and fertile land that was ready to be cleared and planted.

Jersey County was named after the state from which many of the early settlers emigrated- New Jersey. The area quickly evolved into small agricultural communities. As the area soon began to flourish, a county government was established and a courthouse built in Jerseyville, the county seat. The present courthouse is an magnificent architectural structure that was built in 1894.

Today, the county maintains its agricultural base, yet it also features progressive and picturesque communities and breathtaking tourist attractions. Present day Jersey County, a perfect blend of history and progress, is the proud home of over 20,000 people.
