Sully County, located in central South Dakota, has a rich history dating back thousands of years. The region was originally inhabited by Native American tribes, including the Lakota Sioux, who hunted buffalo across the vast plains. 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.

The early 20th century brought challenges to Sully County as it faced the hardships of the Great Depression and the Dust Bowl. Many farmers lost their livelihoods and were forced to leave the area in search of better opportunities. However, the residents of Sully County persevered and adapted, transforming their agricultural practices and implementing soil conservation methods to combat erosion.

Since then, Sully County has continued to thrive as an agricultural community, with ranching and farming remaining the backbone of its economy. The county is known for its production of crops like corn, wheat, and sunflowers, as well as its herds of cattle. In recent years, efforts have been made to diversify the economy by promoting tourism and outdoor recreational activities, taking advantage of the county's stunning natural landscapes and hunting opportunities. Despite its challenges throughout history, Sully County stands as a testament to the resilience and determination of its inhabitants.
