The economic want of the master group has no limits; no man is sufficiently rich to satisfy his desires. The political means are turned on new groups of peasants not yet subjected, or new coasts yet unpilfered are sought out. The primitive state expands, until a collision takes place on the edge of the “sphere of interests” of another primitive state, which itself originated in precisely the same way. Then we have for the first time, in place of the warlike robbery heretofore carried on, true war in its narrower sense, since henceforth equally organized and disciplined masses are hurled at one another.

The object of the contest remains always the same, the produce of the economic means of the working classes, such as loot, tribute, taxes and ground rent; but the contest no longer takes place between a group intent on exploiting and another mass to be exploited, but between two master groups for the possession of the entire booty.

The final result of the conflict, in nearly all instances, is the amalgamation of both primitive states into a greater. This in turn, naturally and by force of the same causes, reaches beyond its borders, devours its smaller neighbors, and is perhaps in its turn devoured by some greater state.

The subjected laboring group may not take much interest in the final issue of these contests for the mastery; it is a matter of indifference whether it pays tribute to one or the other set of lords. Their chief interest lies in the course of the particular fight, which is, in any case, paid for with their own hides. Therefore, except in cases of gross ill treatment and exploitation, the lower classes are rightly governed by their “state-consciousness” when, with all their might they aid their hereditary master group in times of war. For if their master group is vanquished, the subjects suffer most severely from the utter devastation of war. They fight literally for wife and children, for home and hearth, when they fight to prevent the rule of foreign masters.

The master group is involved completely in the issue of this fight for dominion. In extreme cases, it may be completely exterminated, as were the local nobility of the Germanic tribes in the Frankish Empire. Nearly as bad, if not worse, is the prospect of being thrust into the group of the serfs. Sometimes a well-timed treaty of peace preserves their social position as master groups of subordinate rank: e. g., the Saxon nobility in Norman England, or the Suppans in German territory taken from the Slavs. In other cases, where the forces are about equal, the two groups amalgamate into one master group with equal rights, which forms a nobility whose members intermarry. This, for instance, was the situation in the Slavic Territories, where isolated Wendish chieftains were treated as the equals of the Germans, or in mediæval Rome, in the case of prominent families from the Alban Hills and Tuscany.

In this new “primitive feudal state of higher grade,” as we shall call it, the ruling group may, therefore, disintegrate into a number of more or less powerful and privileged strata. The organization may show many varieties because of the well-known fact, that often the master group separates into two subordinated economic and social layers, developed as we saw them in the herdsmen stage: the owners of large herds and of many slaves, and the ordinary freemen. Possibly the less complete differentiation into social ranks in the states created by huntsmen in the new world, is to be assigned to the circumstance that in the absence of herds, the concomitants of that form of ownership, and the original separation into classes, were not introduced into the state. We shall, later, see what force was exerted on the political and economic development of states in the old world by the differences in rank and property of the two strata of rulers.

Similarly, as in the case of the ruling group, a corresponding process of differentiation divides the subject group in the “primitive feudal state of a higher grade” into various strata more or less despised and compelled to render service. It is only necessary to recall the very marked difference in the social and jural position occupied by the peasantry in the Doric States, Lacedæmon and Crete, and among the Thessalians, where the perioiki had clear rights of possession and fairly well protected political rights, while the helots, in the latter case the penestai, were almost unprotected in life and property. Among the old Saxons also we find a class, the liti, intermediate between the common freemen and the serfs.[52] These examples could be multiplied; apparently they are caused by the same tendencies that brought about the differentiation among the nobility mentioned above. When two primitive feudal states amalgamate, their social layers stratify in a variety of ways, which to a certain extent are comparable to the combinations resulting from mixing together two packs of cards.

It is certain that this mechanical mixture caused by political forces, influences the development of castes, that is to say, of hereditary professions, which at the same time form a hierarchy of social classes. “Castes are usually, if not always, consequences of conquest and subjugation by foreigners.”[53] Although this problem has not been completely solved, it may be said that the formation of castes has been very strongly influenced by economic and religious factors. It is probable that castes came about in some such way as this: state-forming forces penetrated into existing economic organizations, and vocations underwent adaptation, and then became petrified under the influence of religious concepts, which, however, may also have influenced their original formation. This seems to follow from the fact that even as between man and woman there exist certain separations of vocation, which, so to say, are taboo and impassable. Thus among all huntsmen, tilling the ground is woman’s work, while among many African shepherds, as soon as the ox-plow is used, agriculture becomes man’s work, and then women may not, under pain of sacrilege, use the domestic cattle.[H]

[H] Similarly there are North Asiatic tribes of huntsmen, where women are definitely forbidden to touch the hunting gear or to cross a hunting trail.—Ratzel I, page 650.

It is likely that such religious concepts may have brought it about that a vocation became hereditary, and then compulsorily hereditary, especially where a tribe or a village carried on a particular craft. This happens with all tribes in a state of nature, where intercourse is easily possible, especially in the case of islanders. When some such group has been conquered by another tribe, the subjects, with their developed hereditary vocations, tend to form within the new state entity a pure “caste.” Their caste position depends partly upon the esteem they had heretofore enjoyed among their own people, and partly upon the advantage which their vocation affords their new masters. If, as was often the case, waves of conquest followed one another in series, the formation of castes might be multiplied, especially if in the meantime economic development had worked out many vocational classes.
