The country was not now divided into a few duchies which, with skilful management, might still in times of emergency have been made to act together. The age of the great duchies was past. As we have seen, Bavaria was shorn of extensive lands, over which new dukes were placed, and the duchy of Saxony was altogether broken up. Swabia and Franconia ceased to have dukes, and Lorraine gave place to the duchy of Brabant and other smaller states. Thus there were archbishops, bishops, abbots, dukes, margraves, landgraves, counts--forming together a large body--each of whom claimed to have no superior save the emperor, whose authority they and their predecessors had slowly destroyed. All immediate nobles were not princes; but even petty knights or barons, who possessed little more than the rude towers from which they descended upon passing travellers, if their only lord was the emperor, recognized no law save their own will. Another independent element of the state was composed of the imperial cities. So long as the emperor really reigned, they enjoyed only such liberties as they could wring from him, or as he voluntarily conferred. But when the sovereign's power decayed, the imperial cities were really free republics, governing themselves according to their own ideas of law and justice (see COMMUNE). Besides the imperial cities, and the princes and other immediate nobles, there were the mediate nobles, the men who held land in fief of the highest classes of the aristocracy, and who, in virtue of this feudal relation, looked down upon the allodial proprietors or freemen, and upon the burghers. There were also mediate towns, acknowledging the supremacy of some lord other than the sovereign. Beneath all these, forming the mass of the agricultural population, were the peasantry and the serfs, the latter attached to the land, the former ground down by heavy taxes. There was another class, large and increasing in number, which was drawn from various sections of society. This was composed of men who, being without land, attached themselves to the emperor or to some powerful noble; they performed services, generally of a military nature, for their lord, and were called _Dienstmannen_ (_ministeriales_). They were often transformed into "free knights" by the grant of a fief, and the class ultimately became absorbed in that of the knights.
