With the introduction of slaves into the tribal economy of the herdsmen, the state, in its essential elements, is completed, except that it has not as yet acquired a definitely circumscribed territorial limit. The state has thus the _form_ of dominion, and its economic basis is the exploitation of human labor. Henceforth, economic differentiation and the formation of social classes progress rapidly. The herds of the great, wisely divided and better guarded by numerous armed servants than those of the simple freemen, as a rule, maintain themselves at their original number: they also increase faster than those of the freemen, since they are augmented by the greater share in the booty which the rich receive, corresponding to the number of warriors (slaves) which these place in the field. Likewise, the office of supreme priest creates an ever-widening cleft which divides the numbers of the clan, all formerly equals; until finally a genuine nobility, the rich descendants of the rich patriarchs, is placed in juxtaposition to the ordinary freemen. “The redskins have also in their progressive organization developed no nobility and no slavery,[C] and in this their organization distinguishes itself most essentially from those of the old world. Both arise from the development of the patriarchate of stock-raising people.”[15] [C] This statement of Lippert is not quite correct. The higher developed domiciled huntsmen and fishermen of Northwest America have both nobles and slaves. Thus we find, with all developed tribes of herdsmen, a social separation into three distinct classes: nobility (“head of the house of his fathers” in the biblical phrase), common freemen and slaves. According to Mommsen, “all Indo-Germanic people have slavery as a jural institution.”[16] This applies to the Arians and the Semites of Asia and Africa as well as to the Hamites. Among all the Fulbe of the Sahara, “society is divided into princes, chieftains, commons and slaves.”[17] And we find the same facts everywhere, as a matter of course, wherever slavery is legally established, as among the Hova[18] and their Polynesian kinsmen, the “Sea Nomads.” Human psychology under similar circumstances brings about like conditions, independent of color or race. Thus the herdsman gradually becomes accustomed to earning his livelihood through warfare, and to the exploitation of men as servile labor motors. And one must admit that his entire mode of life impels him to make more and more use of the “political means.”
