Which of the tribes fought the u. s. army for 10 years to keep their land

The Treaty of Fort Laramie (also the Sioux Treaty of 1868[b]) was an agreement between the United States and the Oglala, Miniconjou, and Brulé bands of Lakota people, Yanktonai Dakota and Arapaho Nation, following the failure of the first Fort Laramie treaty, signed in 1851.

The treaty was divided into 17 articles. It established the Great Sioux Reservation including ownership of the Black Hills, and set aside additional lands as "unceded Indian territory" in areas of South Dakota, Wyoming, and Nebraska, and possibly Montana.[c] It established that the US government would hold authority to punish not only white settlers who committed crimes against the tribes, but also tribe members who committed crimes and who were to be delivered to the government rather than face charges in a tribal courts. It stipulated that the government would abandon forts along the Bozeman Trail, and included a number of provisions designed to encourage a transition to farming, and move the tribes "closer to the white man's way of life." The treaty protected specified rights of third parties not partaking in the negotiations, and effectively ended Red Cloud's War.

It was negotiated by members of the government-appointed Indian Peace Commission, and signed between April and November 1868 at and near Fort Laramie in the Wyoming Territory, with the final signatories being Red Cloud himself and others who accompanied him. Animosities over the agreement arose quickly, with neither side fully honoring the terms. Open war again broke out in 1876, and the US government unilaterally annexed native land protected under the treaty in 1877.

The treaty formed the basis of the 1980 Supreme Court case, United States v. Sioux Nation of Indians, in which the court ruled that tribal lands covered under the treaty 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.
