The third stage arrives when the “surplus” obtained by the peasantry is brought by them regularly to the tents of the herdsmen as “tribute,” a regulation which affords to both parties self-evident and considerable advantages. By this means, the peasantry is relieved entirely from the little irregularities connected with the former method of taxation, such as a few men knocked on the head, women violated, or farmhouses burned down. The herdsmen on the other hand, need no longer apply to this “business” any “expense” and labor, to use a mercantile expression; and they devote the time and energy thus set free toward an “extension of the works,” in other words, to subjugating other peasants. This form of tribute is found in many well-known instances in history: Huns, Magyars, Tartars, Turks, have derived their largest income from their European tributes. Sometimes the character of the tribute paid by the subjects to their master is more or less blurred, and the act assumes the guise of payment for protection, or indeed, of a subvention. The tale is well known whereby Attila was pictured by the weakling emperor at Constantinople as a vassal prince; while the tribute he paid to the Hun appeared as a fee. The fourth stage, once more, is of very great importance, since it adds the decisive factor in the development of the state, as we are accustomed to see it, namely, the union on one strip of land of both ethnic groups.[E] (It is well known that no jural definition of a state can be arrived at without the concept of state territory.) From now on, the relation of the two groups, which was originally international, gradually becomes more and more intra-national. [E] There is apparently in the case of the Fulbe, a transition stage between the first three stages and the fourth, in which dominion is exercised half internationally and half intranationally. According to Ratzel (l. c. II, page 419): “Like a cuttle-fish, the conquering race stretches numerous arms hither and thither among the terrified aborigines, whose lack of cohesion affords plenty of gaps. Thus the Fulbe are slowly flowing into the Benue countries and quite gradually permeating them. Later observers have thus quite rightly abstained from assigning definite boundaries. There are many scattered Fulbe localities which look to a particular place as their center and as the center of their power. Thus Muri is the capital of the numerous Fulbe settlements scattered about the Middle Benue, and the position of Gola is similar in the Adamawa district. As yet there are no proper kingdoms with defined frontiers against each other and against independent tribes. Even these capitals are in other respects still far from being firmly settled.”
