of Godfrey of Bouillon, and the pope's Norman allies being absent in the East, the banners of Germany were suddenly displayed before the walls of Rome. In the spring of 1084 the besiegers entered the Eternal City. Gregory took refuge in the castle of St. Angelo, and Clement III, a rival pontiff, placed the Imperial crown on Henry's brow. But the return of the warlike Normans caused the Imperial troops to retreat with precipitation; while the Roman citizens rising against his allies compelled Hildebrand to fly for shelter to Salerno. There, broken with time and trouble he expired; and his last words were, 'I have loved righteousness and hated iniquity; therefore I die in exile.'
Henry returned to Germany, where he reigned for a while undisturbed by civil war; but Pope Pascal, aspiring to follow in the footsteps of Hildebrand, incited Henry, the Emperor's eldest son, to rebellion; and the youth declaring that he could not acknowledge as king or father a man who was excommunicated, treacherously imprisoned his sire, and assembling a Diet was proclaimed in his stead. Two prelates were sent to demand the regalia from the deposed Emperor; he, receiving them in his symbols of sovereignty, refused; but, laying violent hands on him, they dragged him from his chair, and forcibly divested him of the regal robes. Poor and distressed, Henry escaped from prison, and raised a considerable force to assert his rights; but he died at Liége in 1106, before active operations commenced. His body, denied a resting-place in consecrated ground, was interred in a cave near Spire.
Henry V, though indebted to the Pope for support in his parricidal rebellion, was no sooner established on the Imperial throne, than, reviving the claim of investiture for which his father had contended, he invited the Pope to Germany, that they might settle the dispute. But Pascal having appealed to the King of France, and a fruitless conference having been held at Chalons, Henry entered Italy with eighty thousand men, and after a tedious interview in the church of St. Peter, ordered his guards to take Pascal into custody. The populace of Rome rushed to the Pope's rescue; a battle was fought under the walls; and the carnage was so terrible that the waters of the Tiber were stained with blood. Pascal, taken prisoner, crowned the Emperor, and confirmed the right of investiture; but hardly had Henry departed when the Pope changed his tune, and pronounced a sentence of excommunication. The Emperor once more entered Rome, chased the Pope to the territories of the Norman princes, and marched to take possession of Tuscany, which Matilda, during Hildebrand's visit to Canossa, had bequeathed to the Church. Meanwhile Pascal died, and the States of the Empire having implored Henry to make peace with the new Pope, a Diet was held at Worms, and the matter accommodated. In 1125 a pestilential disease carried Henry to the grave; and the Imperial dignity, after being enjoyed till 1138 by Lothario II, was bestowed upon Henry's nephew, Conrad, duke of Franconia. A rival appeared in the person of the haughty Duke of Bavaria, whose followers called themselves Guelphs, from his family name; while the adherents of the Emperor adopted the appellation of Ghibelines, from Hihghibelin, the village of which Frederick, the brother of Conrad, was a native. Both parties took up arms, and during the contest a romantic incident occurred at the siege of Weinsberg. The Guelphs in the castle, after being long besieged, yielded on condition that the Duke of Bavaria and his officers should be allowed to retire un-
