What describes the 1851 treaty of fort Laramie?

The 1851 Treaty of Fort Laramie was an agreement between the United States and various Native American tribes, including the Lakota, Cheyenne, and Arapaho. It aimed to establish peace and define territorial boundaries, granting tribes specific lands while allowing the U.S. government to build roads and military posts. However, the treaty was later violated by the U.S. as westward expansion continued, leading to increased tensions and conflicts with Native Americans. This treaty marked a significant moment in the U.S. government's approach to Native American relations during westward expansion.
