The Treaty of Fort Laramie in 1851 aimed to establish peace between the U.S. government and various Native American tribes. It officially recognized tribal territories and established boundaries for various tribes residing in the Great Plains. In return, the tribes agreed to allow safe passage for settlers and government officials. Though initially intended to reduce conflict, the treaty's provisions were frequently violated by the U.S. government as westward expansion continued. The treaty's failure to enforce its terms foreshadowed future conflicts over land rights, culminating in further treaties and resistance against encroachment on Native American lands.
