South Dakota : United States

South Dakota was acquired with the 1803 Louisiana Purchase. At that time the region was part of the Sioux and some brave fur trappers. It was only in the 1850s that the rich soil attracted different settlers. South Dakota is not a very rich state but has a vibrant tourism industry.
