Among the Fulbe “society is divided into princes, chieftains, commons and slaves. The slaves of the king play a great rôle as soldiers and officials, and may hope for the highest offices in the state.”[129] This nobility of the court’s creation may, in certain cases, be admitted to the great imperial offices, so that according to the method stated above, it may achieve the sovereignty over a territory. In the developed feudal state, it represents the high nobility; and usually manages to preserve its rank, even when some more powerful neighbor has mediatized it by incorporating the state. The Frankish higher nobility certainly contains such elements from the original lower group;[130] and since from its blood the entire upper nobility of the European civilized states has been descended at least in direct line by marriage, we find an ethnic amalgamation, both in the present day group of subjects and in the highest order of the ruling class. And the same applies to Egypt: “With the sinking of the royal authority in the time of the decay, the higher officials abuse their power for personal ends, to make their offices hereditary in their families, and thereby to call into existence an official nobility not differentiated from the rest of the population.”[131] And finally, the same process, from the same causes, takes hold of the present middle class, the lower stratum of the master class, the officials and officers of the great feudatories. At first there still exists a social difference between, on the one hand, the free vassals, the subfeudatories of the great landlord, kinsmen, younger sons of other noble families, impoverished associates from the same district, in isolated cases freeborn sons of peasants, free refugees and professional ruffians of free descent; and on the other, if the term may be allowed, the subalterns of the guards of plebeian descent. But lack of freedom advances, while freedom sinks in social value; and here too the ruler places more reliance on his creatures than on his peers. Here also, sooner or later, the process of amalgamation becomes complete. In Germany, as late as 1085, the non-free nobility of the court ranks between “_servi et litones_” while a century afterward it is placed with the “_liberi et nobiles_.” In the course of the thirteenth century, it has been completely absorbed, along with the free vassals, into the nobility by chivalry. The two orders in the meantime tend to become equal economically; both have subinfeudations, fiefs on the obligation of service in warfare, and the service feuds of the bondsmen; while all the fiefs of the “ministerials” or sergeants have in the meantime become as heritable as are those of the free vassals, as much so as are the patrimonies of the few surviving smaller territorial lords belonging to the original nobility, who may still have escaped the grasp of the great territorial principalities.
