The Standing Rock Indian Reservation is a Hunkpapa Lakota, Sihasapa Lakota and Yanktonai Dakota Native American reservation in North Dakota and South Dakota in the United States.
The Dakota Access Pipeline protests, also known by the hashtag #NoDAPL, are grassroots movements that began in early 2016 in reaction to the approved construction of Energy Transfer Partners' Dakota Access Pipeline in the northern United States. The pipeline was projected to run from the Bakken oil fields in western North Dakota to southern Illinois, crossing beneath the Missouri and Mississippi Rivers, as well as under part of Lake Oahe near the Standing Rock Indian Reservation. Many in the Standing Rock tribe consider the pipeline and its intended crossing of the Missouri River to constitute a threat to the region's clean water and to ancient burial grounds. In April, Standing Rock Sioux elder LaDonna Brave Bull Allard established a camp as a center for cultural preservation and spiritual resistance to the pipeline; over the summer the camp grew to thousands of people.
