Says Wiki: The Land belongs to the Standing Rock Souix, Swampers broke the treaty, twice

The Wall Street Journal claims otherwise, but the history of Custer getting his ass whooped while trying to deal the land is proof enough.  Rednecks side with the Indians, move he pipeline back into white lands.

WIKI: Together with the Hunkpapa and Blackfoot bands, the Standing Rock Sioux Tribe is part of the Great Sioux Nation. In 1868 the lands of the Great Sioux Nation were reduced in the Fort Laramie Treaty to the east side of the Missouri River and the state line of South Dakota in the west. The Black Hills, considered by the Sioux to be sacred land, are located in the center of territory awarded to the tribe. In direct violation of the treaty, in 1874 General George A. Custer and his 7th Cavalry entered the Black Hills and discovered gold, starting a gold rush. The United States Government wanted to buy or rent the Black Hills from the Lakota people, but the Great Sioux Nation, led by their spiritual leader Sitting Bull, refused to sell or rent their lands. The Great Sioux War of 1876, also known as the Black Hills War, was a series of battles and negotiations which occurred between 1876 and 1877 between the Lakota Sioux and Northern Cheyenne and the government of the United States. Among the many battles and skirmishes of the war was the Battle of the Little Bighorn, often known as Custer's Last Stand, the most storied of the many encounters between the U.S. army and mounted Plains Native Americans. That Native American victory notwithstanding, the U.S. with its superior resources was soon able to force the Native Americans to surrender, primarily by attacking and destroying their encampments and property. The Agreement of 1877 (19 Stat. 254, enacted February 28, 1877) officially annexed Sioux land and permanently established Native American reservations. The Agreement of 1877 allotted Native American lands into 160 acre lots to individuals to divide the nation and the U.S. government took the Black Hills from the Sioux Nation.^[3]In February 1890, the United States government broke a Lakota treaty by adjusting the Great Sioux Reservation, an area that formerly encompassed the majority of the state, and breaking it up into five smaller reservations.^[4] The government was accommodating white homesteaders from the eastern United States; in addition, it intended to "break up tribal relationships" and "conform Indians to the white man's ways, peaceably if they will, or forcibly if they must".^[5] On the reduced reservations, the government allocated family units on 320-acre (1.3 km²) plots for individual households. Although the Lakota were historically a nomadic people living in tipis and their Plains Native American culture was based strongly upon buffalo and horse culture, they were expected to farm and raise livestock. With the goal of assimilation, they were forced to send their children to boarding schools; the schools taught English and Christianity, as well as American cultural practices. Generally, they forbade inclusion of Native American traditional culture and language. They were beaten if they tried to do anything related to their native culture.
