(_Signed, also, by the chiefs and headmen of the Ioway tribe._) TREATY WITH THE SIOUX, ETC., AUG. 19, 1825 _Treaty with the Sioux and Chippewa, Sacs and Fox, Menominie, Ioway, Sioux, Winnebago, and a portion of the Ottawa, Chippewa, and Potawattomie, Tribes._ The United States of America have seen with much regret, that wars have for many years been carried on between the Sioux and the Chippewas, and more recently between the confederated tribes of Sacs and Foxes, and the Sioux; and also between the Ioways and Sioux; which, if not terminated, may extend to the other tribes, and involve the Indians upon the Missouri, the Mississippi, and the Lakes, in general hostilities. In order, therefore, to promote peace among these tribes, and to establish boundaries among them and the other tribes who live in their vicinity, and thereby to remove all causes of future difficulty, the United States have invited the Chippewa, Sac, and Fox, Menominie, Ioway, Sioux, Winnebago, and a portion of the Ottowa, Chippewa, and Potawatomie Tribes of Indians living upon the Illinois, to assemble together, and in a spirit of mutual conciliation to accomplish these objects; and to aid therein, have appointed William Clark and Lewis Cass, Commissioners on their part, who have met the Chiefs, Warriors, and Representatives of the said tribes, and portions of tribes, at Prairie des Chiens, in the Territory of Michigan, and after full deliberation, the said tribes, and portions of tribes, have agreed with the United States, and with one another, upon the following articles: ARTICLE I There shall be a firm and perpetual peace between the Sioux and Chippewas; between the Sioux and the confederated tribes of Sacs and Foxes; and between the Ioways and the Sioux. * * * ARTICLE III The Ioways accede to the arrangement between the Sacs and Foxes, and the Sioux; but it is agreed between the Ioways and the confederated tribes of the Sacs and Foxes, that the Ioways have a just claim to a portion of the country between the boundary line described in the next preceding article, and the Missouri and Mississippi; and that the said Ioways, and Sacs and Foxes, shall peaceably occupy the same, until some satisfactory arrangement can be made between them for a division of their respective claims to country. * * * ARTICLE XI
