Native American group occupies Mount Rushmore to protest broken Treaty of Fort Laramie | August...

Around dusk on the evening on August 29, 1970, a group of 23 Native American activists climbs to the top of Mount Rushmore. Renaming the landmark Crazy Horse Mountain, in honor of the Lakota Sioux leader who famously resisted white Americans’ incursions into the area, the protesters are there to reclaim land they believe to be rightfully theirs under the 1868 Treaty of Fort Laramie, which guaranteed Indigenous people the right to all of Western South Dakota. The occupation will last for two months, beginning a new chapter in Native American activism.

Signed at Fort Laramie in the Wyoming Territory, the 1868 treaty was meant to end hostilities between the United States and the Lakota people, Yanktonai Dakota and Arapaho Nation. The treaty allocated the Black Hills and adjacent lands west of the Missouri River—roughly half of what is now South Dakota—to Indigenous peoples. But it tried to incentivize Native Americans to give up their traditional way of life in favor of farming. And it was designed to assimilate Native Americans into white American culture, with U.S. courts, not tribal ones, given jurisdiction over the reservation.

In a sadly predictable turn of events, the United States broke the treaty within a decade. After George Armstrong Custer’s expedition found gold in the Black Hills region in 1874, white prospectors and settlers rushed into the region, leading to the Great Sioux War of 1876 and American occupation of most of the land promised to the Lakota.
