We have seen that the Papacy did not attain its supremacy without encountering much opposition. But the protests on the part of bishops were unavailing, and they were themselves largely to blame for the height to which the papal power had grown. Such effective remonstrance as there was came from the Kings, though even they were often ready to invoke the papal aid to obtain an advantage against their own ecclesiastics or even their own subjects. Thus in England William II agreed with Urban II that no legate should be sent to the country unless the King was willing to receive him; while Henry II, in the Constitutions of Clarendon, lays it down that no one should appeal to Rome without permission of the King. But Henry's submission after Becket's murder nullified the Constitutions, and John's humiliating surrender made it difficult to object to the exercise of any papal power in England. During the minority of Henry III the papal legate was the most important member of the Council of Regency; and at a later stage, when Henry had quarrelled with his barons, he was glad to obtain the papal support against them. In Germany Hadrian IV complained that Frederick I used force in order to prevent any of his subjects from carrying their causes to Rome; and Otto IV was obliged to swear in 1209 that no hindrance should be placed to ecclesiastical appeals to Rome, a promise subsequently exacted also from Frederick II and from Rudolf. Not dissimilar was the submission of Alfonso X of Castile, who set his seal to the papal encroachments; but his object was to obtain the support of Rome in his campaign against the local liberties in his kingdom. In his code of law known as "Siete Partidas" power was given to the Pope to deal as he liked with bishops and with benefices and to receive all appeals. On the other hand, St. Louis was not above a bargain with Rome. He refused to the Pope the tithes of the French Church for three years for the object of carrying on the war against Frederick II; but in 1267 he himself obtained the papal consent to take these tithes for the purpose of crusade.
