The result of these negotiations was the treaty of Medicine Lodge on October 21, 1867, by which the Kiowa, Comanche, and Apache were officially confederated and agreed to come upon their present reservation (see the calendar). This treaty merits extended notice, inasmuch as it changed the whole status of the Kiowa and their allies from that of independent tribes with free and unrestricted range over the whole plains to that of pensioners dependent on the government, confined to the narrow limits of a reservation and subject to constant military and civilian supervision. For them it marks the beginning of the end. Moreover, on the provisions and promises of this treaty are based all the arguments for and against the late unratified agreement of 1892. It will be necessary first to review the situation. For a number of years the Indian problem on the plains had been constantly growing more serious. The treatment accorded by Texas to her native and border tribes had resulted in driving them northward to the country of upper Red river and the vicinity of the Santa Fé trail, where they were a constant menace both to the trading caravans and to the frontier settlers of Kansas and Colorado. In addition to the old Santa Fé trail the thousands of emigrants to California and Oregon had established regular roads across the plains, in the north along the North Platte and in the south along the base of the Staked plain, while the discovery of gold in Colorado in 1858 brought a flood of white settlement into the very heart of the Indian country, driving away the buffalo and narrowing the range of the tribes. Encroachments and reprisals were becoming chronic, and it was evident that some arrangement must be made by which the wild tribes could be assigned a territory remote from the line of settlement and travel, where they might roam and hunt undisturbed, without danger of coming into collision with the whites. The conditions a few years previous are well summed up by the veteran trader William Bent, at that time agent for the Cheyenne and Arapaho, in an official report dated October 5, 1859. In it he says: The Cheyenne and Arapahoe tribes scrupulously maintain peaceful relations with the whites and with other Indian tribes, notwithstanding the many causes of irritation growing out of the occupation of the gold region, and the emigration to it through their hunting grounds, which are no longer reliable as a certain source of food to them. These causes precipitate the necessity of immediate and sufficient negotiations for the safety of the whites, the emigrant roads, and the Indians....
