The Caddoan family is less clearly defined than either of the preceding, but evidently consisted of many small tribes grouped, and forming confederacies. Those to be mentioned later include: (1) The Arikara; (2) the Pawnee confederacy, composed of four tribes—(a) Chaui or Grand Pawnee, (b) Kitkehahki or Republican Pawnee, (c) Pitahauerat or Tapage Pawnee, (d) Skidi or Wolf Pawnee; (3) the Wichita confederacy, including the Waco and various small tribes; (4) the Caddo proper.
Although the latter are included in the same linguistic group with the Arikara, Pawnee, and others as mentioned above, they are regarded by some as constituting a distinct linguistic stock.
During the years following the close of the Revolution, the latter part of the eighteenth century, many tribes, or rather the remnants of tribes, then living east of the Mississippi, sought a refuge in the West beyond the river. Many settled on the streams in the southern part of the present State of Missouri and northern Arkansas, and, as stated by Stoddard when writing about the year 1810: "A considerable number of Delawares, Shawanese, and Cherokees, have built some villages on the waters of the St. Francis and White Rivers. Their removal into these quarters was authorized by the Spanish government, and they have generally conducted themselves to the satisfaction of the whites. Some stragglers from the Creeks, Chocktaws, and Chickasaws, who are considered as outlaws by their respective nations, have also established themselves on the same waters; and their disorders and depredations among the white settlers are not unfrequent." (Stoddard, (1), pp. 210-211.) And at about the same time another writer, referring to the same region, said: "Below the Great Osage, on the waters of the Little Osage, Saint Francis, and other streams, are a number of scattered bands of Indians, and two or three considerable villages. These bands were principally Indians, who were formerly outcasts from the tribes east of the Mississippi. Numbers have since joined from the Delawares, Shawanoes, Wayondott, and other tribes towards the lakes. Their warriors are said to be five or six hundred. They have sometimes made excursions and done mischief on the Ohio river, but the settlements on the Mississippi have suffered the most severely by their depredations." (Cutler, (1), p. 120.)
No attempt will be made in the present work to describe the habitations or settlements occupied by the scattered bands just mentioned.
It is quite evident that during the past two or three centuries great changes have taken place in the locations of the tribes which were discovered occupying the region west of the Mississippi by the first Europeans to penetrate the vast wilderness. Thus the general movement of many Siouan tribes has been westward, that of some Algonquian groups southward from their earlier habitats, and the Caddoan appear to have gradually gone northward. It resulted in the converging of the tribes in the direction of the great prairies occupied by the vast herds of buffalo which served to attract the Indian. Until the beginning of this tribal movement it would seem that a great region eastward from the base of the Rocky Mountains, the rolling prairie lands, was not the home of any tribes but was solely the range of the buffalo and other wild beasts, which existed in numbers now difficult to conceive.
