By the time three federal government agencies issued their joint statement halting construction of the Dakota Access pipeline on September 9, there were some 5,000 protesters on site in Cannon Ball, North Dakota challenging the project. The groups spreadout over a massive campsite on the Standing Rock Sioux reservation, where the tribe says the proposed construction of the pipeline threatens their water source and sacred lands.
After hearing about the Standing Rock resistance, Native groups from all over the world came to stand in solidarity with the Sioux, traveling from Canada, Mexico, Brazil, and the Ecuadorian Amazon. The thousands of demonstrators represented some 280 different indigenous tribes, by far the largest Native American protest in recent memory and perhaps one of the largest ever recorded.
