The southwestern Indians were called Appalachians by the olden writers, because this was the name then given to the southern Alleghanies. It is doubtful if the term has any exact racial significance; but it serves very well to indicate a number of Indian nations whose system of government, ways of life, customs, and general culture were much alike, and whose civilization was much higher than was that of most other American tribes. The Appalachians were in the barbarous, rather than in the merely savage state. They were divided into five lax confederacies: the Cherokees, Chickasaws, Choctaws, Creeks, and Seminoles. The latter were merely a southern offshoot of the Creeks or Muscogees. They were far more numerous than the northwestern Indians, were less nomadic, and in consequence had more definite possession of particular localities; so that their lands were more densely peopled. In all they amounted to perhaps seventy thousand souls.[1] It is more difficult to tell the numbers of the different tribes; for the division lines between them were very ill defined, and were subject to wide fluctuations. Thus the Creeks, the most formidable of all, were made up of many bands, differing from each other both in race and speech. The languages of the Chickasaws and Choctaws did not differ more from the tongue of the Cherokees, than the two divisions of the latter did from each other. The Cherokees of the hills, the Otari, spoke a dialect that could not be understood by the Cherokees of the lowlands, or Erati. Towns or bands continually broke up and split off from their former associations, while ambitious and warlike chiefs kept forming new settlements, and if successful drew large numbers of young warriors from the older communities. Thus the boundary lines between the confederacies were ever shifting.[2] Judging from a careful comparison of the different authorities, the following estimate of the numbers of the southern tribes at the outbreak of the Revolution may be considered as probably approximately correct. The Cherokees, some twelve thousand strong,[3] were the mountaineers of their race. They dwelt among the blue-topped ridges and lofty peaks of the southern Alleghanies,[4] in the wild and picturesque region where the present States of Tennessee, Alabama, Georgia, and the Carolinas join one another.
