In 1803, the Louisiana Purchase brought the region under the control of the United States, and the Lewis and Clark expedition passed through what is now Yankton County in 1804. This led to increased American presence in the area, and in 1859, Yankton was officially designated as the capital of the Dakota Territory. The County was established in 1862, during the early stages of the American Civil War.
Yankton County played a significant role in the development of the Dakotas. It served as the territorial capital until 1889 when South Dakota became a state. The county saw rapid growth during this time, with the construction of railroads and the establishment of businesses. Agriculture, including farming and livestock, formed the backbone of the local economy, and Yankton became a major center for trade and commerce.
Over the years, Yankton County has faced various challenges and changes. The decline of the agricultural sector in the early 20th century led to a shift towards other industries like manufacturing and healthcare. Today, the county continues to thrive as a vibrant community, with a strong emphasis on education, tourism, and outdoor recreational activities. Overall, the history of Yankton County reflects the dynamic nature of American expansion and the resilience of its inhabitants.
