Succeeding cultures of indigenous peoples lived along the Missouri River for thousands of years. By 1775, the Omaha people had migrated west of the Missouri, where they established a major settlement, which they called Ton-wa-tonga, meaning the Big Village. It had about 1100 residents. From here, the Omaha controlled fur trading on the upper Missouri River with other tribes and with French-Canadian traders, often called voyageurs. The Omaha were the first of the Northern Plains tribes to have adopted an equestrian culture.
Dakota County was formed by European-American settlers in 1855. They named it after the historic Dakota Sioux tribe, who were powerful in the area of Nebraska and South Dakota. By this time, the Omaha were concentrated further south in what became the state of Nebraska.
