The Pope answered with excommunication and a demand that the German princes rid themselves of their unworthy ruler. The German princes, only too happy to be rid of Henry, asked the Pope to come to Augsburg and help them elect a new Emperor. Gregory left Rome and travelled northward. Henry, who was no fool, appreciated the danger of his position. At all costs he must make peace with the Pope, and he must do it at once. In the midst of winter he crossed the Alps and hastened to Canossa where the Pope had stopped for a short rest. Three long days, from the 25th to the 28th of January of the year 1077, Henry, dressed as a penitent pilgrim (but with a warm sweater underneath his monkish garb), waited outside the gates of the castle of Canossa. Then he was allowed to enter and was pardoned for his sins. But the repentance did not last long. As soon as Henry had returned to Germany, he behaved exactly as before. Again he was excommunicated. For the second time a council of German bishops deposed Gregory, but this time, when Henry crossed the Alps he was at the head of a large army, besieged Rome and forced Gregory to retire to Salerno, where he died in exile. This first violent outbreak decided nothing. As soon as Henry was back in Germany, the struggle between Pope and Emperor was continued. The Hohenstaufen family which got hold of the Imperial German Throne shortly afterwards, were even more independent than their predecessors. Gregory had claimed that the Popes were superior to all kings because they (the Popes) at the Day of Judgement would be responsible for the behaviour of all the sheep of their flock, and in the eyes of God, a king was one of that faithful herd.
