The name "Dakota" refers to theDakota people.^[9]

The territory now known as the Dakotas includes a large portion of the ancestral land ofNative American tribes, in particular various tribes ofSioux such as theDakota people, also known as the SanteeSioux. The United States government stakes its claim to the land through theLouisiana Purchase andRupert's Land acquisition. The region historically involved a complex series of conflicts between the U.S. government and Native American tribes (and among themselves).

The region was part of theMinnesota andNebraska territories until 1861.Dakota Territory initially included parts of present day Montana, Nebraska and Wyoming. The fall of 1861 resulted in a poor harvest and was followed by a harsh winter, leading to extreme hardship for the Dakota in the region. Desperate for food and money, they were denied loans by local traders. A series of raids in the spring of 1862 ultimately resulted inDakota War of 1862 between the U.S. government and the Dakota people. The U.S. won the war, the aftermath which included a mass hanging of 38 people on December 26, 1862, the largest mass execution in U.S. history. The remaining Santee Dakota people were exiled by the U.S. government to the Dakota Territory.^[10]

The end of the war did not solve the conflicts between Native Americans and the Americans. Fighting would continue, for example along theBozeman Trail, until theTreaty of Fort Laramie in 1868. The treaty established theGreat Sioux Reservation and "designated the Black Hills as 'unceded Indian Territory' for the exclusive use of native peoples."^[11] The subsequent discovery of gold in the Black Hills in 1874 byGeorge Armstrong Custer'sBlack Hills Expedition, would cause agold rush and the U.S. to violate the treaty. TheIndian Appropriations Act of 1876 went into effect on August 15, 1876. This was referred to as "sell or starve" by the Native Americans and led to theGreat Sioux War of 1876. The conflict between the Sioux and miners and the U.S. forces backing them would culminate in theBattle of the Little Bighorn, also known as "Custer's Last Stand", the most significant battle of the war. Despite being a Sioux victory, Battle of the Little Bighorn preceded theAgreement of 1877 which took away the Black Hills and forced Native Americans onto reservations (seeBlack Hills land claim) and left the Sioux with little means to address their grievances.

Before he left office, President Cleveland signed a bill on February 22, 1889, splitting the Dakota Territory along the modern borders. This bill was ratified by Congress, and President Harrison signed the paper work to create the US states of North Dakota and South Dakota on November 2, 1889, deliberately signing such that it was unknown which was officially created first.

The debate over the land within the Dakotas, specifically the Black Hills, is unsettled. The Sioux in 1920 began a legal battle over their ancestral lands within the US system of justice. Sixty years later, the US Supreme Court upheld in 1980'sUnited States v. Sioux Nation of Indians case that tribal land was illegally taken from the Sioux and ruled they deserved financial compensation. The Sioux Nation has refused the offer because the land was "never for sale".^[11]

The Dakotas have a total area of 147,878 square miles (383,177 square kilometers), which would rank 4th among U.S. states, right beforeMontana.

The Dakotas are within theMidwestern United States, with the western portion in theHigh Plains. ThePBS miniseriesNew Perspectives on the West noted historically important areas within the Dakotas, including theBlack Hills, the town ofDeadwood,Fort Buford,Standing Rock Reservation andWounded Knee.^[12] The UpperMissouri River and the UpperMissouri River Valley are important geological features in the area, as well.

Both of the Dakotas havehumid continental climate, with warm to hot summers and cold to evensubarctic temperatures in winter. Due to the difference incircle of latitude, temperatures differ by degrees between the southern and northern areas, even inside the respective states.

The two states combined have a population of 1,670,324, slightly less thanIdaho, ranking at 39th place. The two states also have a population density of 9.8 per sq. mi (3.8 per km²).

The area is mostly inhabited by people of Northern European origin. 44.9% of the population are of German ancestry, 21.8% of Norwegian, and 9.6% are of Irish heritage.^{[citation needed]}
