But more frequently the Pope was the stronger. Then the Emperor or the King together with all his subjects was excommunicated. This meant that all churches were closed, that no one could be baptised, that no dying man could be given absolution—in short, that half of the functions of mediæval government came to an end. More than that, the people were absolved from their oath of loyalty to their sovereign and were urged to rebel against their master. But if they followed this advice of the distant Pope and were caught, they were hanged by their near-by Liege Lord and that too was very unpleasant. Indeed, the poor fellows were in a difficult position and none fared worse than those who lived during the latter half of the eleventh century, when the Emperor Henry IV of Germany and Pope Gregory VII fought a two-round battle which decided nothing and upset the peace of Europe for almost fifty years. In the middle of the eleventh century there had been a strong movement for reform in the church. The election of the Popes, thus far, had been a most irregular affair. It was to the advantage of the Holy Roman Emperors to have a well-disposed priest elected to the Holy See. They frequently came to Rome at the time of election and used their influence for the benefit of one of their friends. In the year 1059 this had been changed. By a decree of Pope Nicholas II the principal priests and deacons of the churches in and around Rome were organised into the so-called College of Cardinals, and this gathering of prominent churchmen (the word “Cardinal” meant principal) was given the exclusive power of electing the future Popes. [Illustration: THE CASTLE] In the year 1073 the College of Cardinals elected a priest by the name of Hildebrand, the son of very simple parents in Tuscany, as Pope, and he took the name of Gregory VII. His energy was unbounded. His belief in the supreme powers of his holy office was built upon a granite rock of conviction and courage. In the mind of Gregory, the Pope was not only the absolute head of the Christian church, but also the highest Court of Appeal in all worldly matters. The Pope who had elevated simple German princes to the dignity of Emperor could depose them at will. He could veto any law passed by duke or king or emperor, but whosoever should question a papal decree, let him beware, for the punishment would be swift and merciless. Gregory sent ambassadors to all the European courts to inform the potentates of Europe of his new laws and asked them to take due notice of their contents. William the Conqueror promised to be good, but Henry IV, who since the age of six had been fighting with his subjects, had no intention of submitting to the Papal will. He called together a college of German bishops, accused Gregory of every crime under the sun and then had him deposed by the council of Worms.
