About Stanley County

Stanley County, South Dakota, has a rich and fascinating history that dates back thousands of years. The area was originally inhabited by various Native American tribes, including the Lakota Sioux. They relied on the vast prairies and the Missouri River for their livelihoods. European settlers began arriving in the 1800s, with the explorations of Lewis and Clark leaving a significant impact on the region's history.

In 1873, Stanley County was established and named after a Civil War General, David S. Stanley. The county's first settlements were established along the Missouri River, particularly the town of Fort Pierre, which became the county seat. Fort Pierre served as a major trading post and served as an important link to the Black Hills during the Gold Rush.

During the late 1800s and early 1900s, Stanley County experienced a boom in agriculture and the cattle industry. Large-scale ranching operations and farms were established, and the county's economy thrived. The arrival of the Chicago and North Western Railway in the early 1900s further stimulated economic growth and connected Stanley County to the rest of South Dakota.

In more recent years, Stanley County has continued to be a predominantly rural and agricultural region. It is known for its fertile farmlands, ranches, and scenic beauty, including parts of the Missouri River. The county is also home to several outdoor recreational opportunities, such as hunting, fishing, and boating.
