The royal revenues came from the king’s demesne and from his share of the tributes that Poles, Czechs, Wends, and Danes paid whenever he could enforce his claims of overlordship. There were also profits from tolls and mints that had not yet been granted away. The king’s demesne was his working capital. He and his household lived on its produce during their wanderings through the Reich, and he used its revenue to provide for his family, to found churches, and to reward faithful services done to him, especially in war. To swell his army, the king needed to add new vassals, and he inevitably had to grant land to some of them from his own demesne. Although the Salians inherited the remains of Ottonian wealth as an imperial demesne, they brought little of their own to make up for its diminution. The last Ottonian, Henry II (1002–24), and after him Conrad II, accordingly took to enfeoffing vassals with lands taken from the monasteries. Since the beneficiaries were often already powerful and wealthy men in their own right, no class of freeborn, mounted warriors linked permanently with the crown resulted from the loyalties established and rewards granted during but one or two reigns. In any case, the lion’s share of grants went to the German church.

From the Carolingians the German kings inherited their one and only institution of central government: the royal chapel, with the chancery that does not seem to have been distinct from it. Service there became a recognized avenue of promotion to the episcopate for highborn clerics. In the 11th century bishops and abbots conducted the affairs of the Reich much more than the lay lords, even in war. They were its habitual diplomats and ambassadors. Unlike Henry I, Otto I and his successors sought to free the prelates from all forms of subjection to the dukes. The king appointed most of them, and to him alone, as to one sent by God, they owed obedience.

Thus there arose beside the loose association of tribal duchies in the German kingdom a more compact and uniform body with a far greater vested interest in the Reich: the German church. By ancient Germanic custom, moreover, the founder of a church did not lose his estate in the endowment that he had made; he remained its proprietor and protecting lord. Still, the bishoprics and certain ancient abbeys, such as Sankt Gallen, Reichenau, Fulda, and Hersfeld, did not belong to the king; they were members of the kingdom, but he served only as their guardian. The greater churches therefore had to provide the rulers with mounted men, money, and free quarters. Gifts of royal demesne to found or to enrich bishoprics and convents were not really losses of land but pious reinvestments, as long as the crown controlled the appointments of bishops and abbots. The church did not merely receive grants of land, often uncultivated, to settle, develop, and make profitable; it was also given jurisdiction over its dependents. Nor did the kings stint the prelates in other regalian rights, such as mints, markets, and tolls. These grants broke up counties and to some extent even duchies, and that was their purpose: to disrupt the secular lords’ jurisdictions that had escaped royal control.

This policy of fastening the church, a universal institution, into the Reich, with its well-defined frontiers, is usually associated with Otto I, but it gathered momentum only in the reigns of his successors. The policy reached a climax under Henry II, the founder of the see of Bamberg in the upper Main valley; nonetheless, Conrad II, though less generous with his grants, and his son Henry III continued it. Bishops and abbots became the competitors of lay princes in the formation of territories, a rivalry that more than any other was the fuel and substance of the ceaseless feuds—the smoldering internal wars in all the regions of Germany for many centuries. The welter and the confused mosaic of the political map of Germany until 1803 is the not-so-remote outcome of these 10th- and 11th-century grants and of the incompatible ambitions that they aroused.
