272 A BRIEF SURVEY OF HUMAN HISTORY southern realms and may be said to have founded the first modern well-regulated state, in which the king was indisputably supreme."1 In his earlier years he was the contemporary of Innocent III, one of the greatest of the Popes. Though he had been brought up under the Muslim Culture of Sicily (the island was under the Saracens from 827—1060) Frederick II had pro- mised Innocent III to go on a Crusade some- time. In the fulfilment of this undertaking Frederick proved eminently successful, for he actually brought the Holy City (Jerusalem) under Christian rule and was him- self declared its king. But this was a shortlived triumph. The Popes were not to be appeased. Their rivalries once again revived, and Frederick like Henry IV was excommuni- cated and deposed. After his death, in 1250, Sicily was lost to the Hohenstaufens. The Pope bestowed the island upon its French conquerors under Charles Anjou, the brother of St. Louis. Thus ended the German attempt to revive the glories of the Roman Empire. Europe, particularly Central Europe, continued to welter in anarchy, though Ger- man kings pompously proclaimed themselves Emperors. A confused group of duchies, counties, bishoprics, arch- bishoprics, abbacies, free towns, and all manner of feudal estates, asserted each its practical independence of the nomi- nal kings. There was to be no imperial way yet out of the chaos of the Middle Ages. 1. Robinson, op. tit., p. 136.
