None of the other tribes that signed the 1851 treaty fought with American soldiers,:LVII:54:161:xi and most of the army`s allies. :91:127:161:129 With the intertribal peace of 1851, soon broken:572-3:226, 228:103:119, 125-140, 178 called arikara, Hidatsa and Mandan for American military support against the Sioux Indians in 1855. 106 In the summer of 1862, the three tribes had left all their permanent villages of land refuges in the contracted area south of Missouri, which was now under Sioux`s control, and lived together in the village of Like-a-Fish-hook north of the river. :108408 Arapahoe (North Arapaho) settled on the reserve of their former enemies, the Shoshone, in the present-day Wind River Reserve in Wyoming.  The Southern Cheyenne and Arapaho live on a common reserve in Present Oklahoma, also far from their 1851 contract country.  Section 7 dealt with education for children aged 6 to 16, in order to ensure, as the treaty states, „the civilization of the Indians who conclude this treaty.“ :5 Tribes agreed to force men and women to go to school, and the government agreed to make a school and a teacher available to each of the 30 students who could be brought to participate.  Financial arbitration could help lift the tribes of the Sioux nation out of poverty and provide services to deal with domestic violence and drug abuse – problems that followed the collapse of their traditional social structure by the United States. But money alone will not give the people of the Sioux nation what they are looking for. As important as the Holy Land itself is, the sovereign right to which they aspire is the recognition that representatives of the U.S. government met with representatives of tribal nations on an equal footing only five generations ago in the Northern Plains, where one nation made a promise to another. It would be easy to think of this 150-year-old document as an artifact of America`s uncomfortable past, says Darrell Drapeau, a member of the Yankton Sioux Tribal Council, which teaches American Indian studies at Ihanktowan Community College.
But it is important to remember, he says, that the U.S. Constitution – a document that determines daily life in America – was signed almost four generations ago, 231 years ago. The contract was terminated almost immediately after its creation.
