Although the name Ponka did not appear in history before 1700 it must have been used for many generations earlier, since it is an archaic designation connected with the social organization of several tribes and the secret societies of the Osage and Kansa, as well as the Ponka. In 1700 the Ponka were indicated on De l’Isle’s map, though they were not then segregated territorially from the Omaha. They, too, suffered terribly from the smallpox epidemic, and when met by Lewis and Clark in 1804 numbered only about 200. They increased rapidly, reaching about 600 in 1829 and some 800 in 1842; in 1871, when they were first visited by Dorsey, they numbered 747. Up to this time the Ponka and Dakota were amicable; but a dispute grew out of the cession of lands, and the Teton made annual raids on the Ponka until the enforced removal of the tribe to Indian Territory took place in 1877. Through this warfare, more than a quarter of the Ponka lost their lives. The displacement of this tribe from lands owned by them in fee simple attracted attention, and a commission was appointed by President Hayes in 1880 to inquire into the matter; the commission, consisting of Generals Crook and Miles and Messrs William Stickney and Walter Allen, visited the Ponka settlements in Indian Territory and on the Niobrara and effected a satisfactory arrangement of the affairs of the tribe, through which the greater portion (some 600) remained in Indian Territory, while some 225 kept their reservation in Nebraska.
