Chapter VII (iii)
In Italy the stage was now set for a confrontation between the Pope and the King of the Romans. Victor III, however, would not live to see its resolution. As Heinrich was starting his ascent of the alps the Pope died in his bed, presumably of a heart attack. The Curia quickly elected a new Pope who took the name Urban II. Once installed he quickly put pressure on Roger Borsa who had been reluctant to take a stand against Heinrich. After some discussion, which we may assume included equal amounts of threats and bribes, he was able to bring the Norman Duke around. Roger mobilized his army and marched north to meet the approaching Germans.
When Heinrich had heard of the death of Pope Victor III he had immediately set up the bishop of Salzburg, whom he had dragged along with his army, as an anti-Pope. Furious, Urban II excommunicated the both of them. Heinrich, calling Urban II an imposter, then declared the Pope deposed. His army made straight for Rome so that he might make good on his declaration. They were intercepted along the way, however, by the Normans. Roger Borsa, who despite his initial reluctance had no wish to see a resurgence of Imperial power in Italy, had quietly moved his army north of Rome. As the Germans moved through Tuscany they were ambushed by the Normans. Accounts of the battle give us images ofo Norman soldiers pouring down out of the hills and charging into the unsuspecting German columns. The battle was a rout; the way to Rome was now closed. Humiliated, Heinrich had no choice but to come to terms. The King of the Romans met the Pope in Oviedo and made his obeisance, begging forgiveness for his transgressions against the Holy Church. Heinrich was forced to confirm the right of Papal investiture for all the bishoprics in the Holy Roman Empire, grant further secular powers to the churches and monasteries and, per usual, pay a hefty sum. The poor bishop of Salzburg, who had never wanted to be Pope in the first place, was to be thrown in prison but he managed to flee to Norway where he lived out his life in exile. Now there was nothing left for Heinrich but to slink back northwards to his court in Nassau. Trouble was brewing in his German provinces and he would spend the next decade fighting to hang on to his throne.
And what, you might ask, was Alexius doing during all this? The conflict in Italy had put the Basileus in an interesting position. Defeat for either side would be good news for the Byzantines so long as it didn’t lead to a significant gain for the other. Alexius was not eager to see the upstarts in the West, those pretentious Franks who dared style themselves “Emperor,” lay claim to land that rightfully belonged to the true Roman Empire. Neither would it be desirable for the Normans of Apulia to emerge with greater authority. Faced with this delicate dilemma he had decided to support neither side and simply let them smash each other to bits; all the better for him to move in afterwards and pick up the pieces. But the fighting had not lasted long enough for an appreciable weakening of either side. So Alexius turned south to another former province: Sicily, now in the hands of the Saracens.
