Throughout the 20th and 21st centuries, the Dakota and Lakota would continue to fight for their treaty rights, including the Wounded Knee incident, Dakota Access Pipeline protests and the 1980 Supreme Court case, "United States v. Sioux Nation of Indians", in which the court ruled that tribal lands covered under the Fort Laramie Treaty of 1868 had been taken illegally by the US government, and the tribe was owed compensation plus interest. As of 2018, this amounted to more than $1 billion; the Sioux have refused the payment, demanding instead the return of their land. Today, the Sioux maintain many separate tribal governments scattered across several reservations, communities, and reserves in North Dakota, South Dakota, Nebraska, Minnesota, and Montana in the United States; and Manitoba, southern Saskatchewan, and Alberta in Canada.
