European settlers began arriving in the area in the 1800s, drawn by the promise of vast expanses of fertile land.

In 1883, Sully County was officially established and named after General Alfred Sully, a prominent military figure during the American Civil War. The county quickly flourished as new settlers arrived, establishing farms and ranches. The construction of the Chicago, Milwaukee, St. Paul and Pacific Railroad in the late 19th century further enhanced the county's growth, improving transportation and facilitating trade.

Since then, Sully County has continued to thrive as an agricultural community, with ranching and farming remaining the backbone of its economy.
