[Sidenote: =Henry's servility to the pope.--Exasperation of the baronage.=] Far worse for England than Henry's abortive invasion of France were his dealings with the papacy. Henry was a devoted servant of the Church, and whenever the Popes tried to lay any burden on England, Henry did his best to make the nation submit. Rome was at this time deep in a struggle with the brave and brilliant Emperor Frederic II., and the Popes were always wanting money to keep up the war against him. In 1238 Gregory IX. sent over to England his legate, Cardinal Otho, who pretended to come to reform the clergy, but really did little more than extort great sums of money from them, on all possible excuses. When he left the realm it was said that he took more English Church treasure with him than he left behind, and he had thrust 300 Italian priests into English benefices by the aid of the king's patronage. A few years later Henry allowed himself to be made the Pope's tool in an even more disgraceful way. Alexander IV. was trying to wrest the kingdom of Sicily from the heirs of the Emperor Frederic II., and, as he could not succeed by his own strength, determined to make the docile King of England do the work for him. So he offered to make Henry's younger son Edmund, a boy of ten, King of Sicily, if Henry would undertake the expense of conquering that country. The scheme was just one of the wild adventurous plans that took the flighty monarch's fancy, so he eagerly accepted the Sicilian crown for his son, and promised the Pope that he would find the money to raise a great army. But as he had never any gold in his own treasury--since he spent it all on his buildings and his wife's relatives--he had to raise the great sums required for the invasion of Sicily out of the nation. In 1257, therefore, he summoned the Great Council, and told them that he must at once have liberal grants from them, because he had pledged England's credit to the Pope, and had made the realm responsible to Alexander IV. for 140,000 marks. The baronage were full of rage and disgust, for the conquest of Sicily was no concern of England's, but a matter of private spite on the part of the papacy. And, moreover, the king had not the least right to pledge the revenues of England to Alexander without having consulted the Great Council. Instead, therefore, of a grant of 140,000 marks, Henry received the outpourings of thirty years of suppressed indignation and discontent. He was told that he could no longer be allowed to rule the realm without the aid and counsel of his barons; that his interference in distant wars was foolish; that his foreign relations were a flight of locusts eating up the land; that his ministers and favourites were unjust, greedy, and extortionate. The king was seriously frightened, and consented to call another Great Council together at Oxford, to provide for the better governance of the realm, and not merely for the payment of his own debts.
