The Pope was more successful in a contest waged with tongues than he had proved on battle-fields, which were strewn with bodies of both Guelf and Ghibelline factions. He dined in 1230 at the same table as his foe, but the peace between them did not long continue. In turn they triumphed, bringing against each other two armies of the Cross, the followers of the Pope fighting under the standard of St Peter's Keys as the champion of the true Christian Church against its oppressors.
Pope Innocent IV, who succeeded Gregory, proved himself a very cunning adversary. He might have { 17} won an easy victory over Frederick II if the exactions of the Papacy had not angered the countries where he sought refuge after his first failures. It was futile to declare at Lyons that the Emperor was deposed when all France was crying out upon the greed of prelates. The wearisome strife went on till the very peasants had to be guarded at their work by knights, sent out from towns to see that they were not taken captive. It was the day of the robber, and all things lay to his hand if he were bold enough to grasp them. Prisoners of war suffered horrible tortures, being hung up by their feet and hands in the hope that their friends would ransom them the sooner. Villages were burned down, and wolves howled near the haunts of men, seeking food to appease their ravening hunger. It was said that fierce beasts gnawed through the walls of houses and devoured little children in their cradles. Italy was rent by a conflict which divided one province from another, and even placed inhabitants of the same town on opposite sides and caused dissension in the noblest families.
The Flagellants marched in procession through the land, calling for peace but bringing tumult. The Emperor's party made haste to shut them out of the territory they ruled, but they could not rid the people of the terrible fear inspired by the barefooted, black-robed figures, with branches and candles in their hands and the holy Cross flaming red before them.
One defeat after another brought the House of Hohenstaufen under the control of the Church they had defied so boldly. Frederick's own son rebelled against him, and Frederick's camp was destroyed by a Guelf army. The Emperor had lived splendidly, making more impression on world-history than any other prince of that { 18} illustrious family, but he died in an hour of failure, feeling bitterly how great a triumph his death would be to the Pope who had conquered.
