Buckskin

Before Aberdeen or Brown County was inhabited by European settlers, it was inhabited by the Sioux Indians from approximately 1700 to 1879. Europeans entered the region for business, founding fur trading posts during the 1820s; these trading posts operated until the mid-1830s. The first "settlers" of this region were the Arikara Indians, but they would later be joined by others. The first group of Euro-American settlers to reach the area that is now Brown County was a party of four people, three horses, two mules, fifteen cattle, and two wagons. This group of settlers was later joined by another group the following spring, and, eventually, more settlers migrated toward this general area, currently known as Columbia, South Dakota.
