South Dakota is named after the Lakota and Dakota Sioux Native American tribes, who comprise a large allowance of the population following nine reservations currently in the come clean and have historically dominated the territory. South Dakota is the seventeenth largest by area, but the 5th least populous, and the 5th least densely populated of the 50 United States. As the southern share of the former Dakota Territory, South Dakota became a state on November 2, 1889, simultaneously in the same way as North Dakota. They are the 39th and 40th states admitted to the union; President Benjamin Harrison shuffled the statehood papers since signing them fittingly that no one could say which became a let in first.Pierre is the divulge capital, and Sioux Falls, with a population of not quite 187,200, is South Dakota’s largest city.
South Dakota is bordered by the states of North Dakota (to the north), Minnesota (to the east), Iowa (to the southeast), Nebraska (to the south), Wyoming (to the west), and Montana (to the northwest). The let pass is bisected by the Missouri River, dividing South Dakota into two geographically and socially clear halves, known to residents as “East River” and “West River”.
