Devoid of heart and conscience though he might be, Henry V was by no means deficient in the prudence and capacity for government which had characterised his forefathers. He possessed resolution and boldness; but he was hasty and precipitate, and often frustrated his own great purposes by acts of arbitrary violence. The papal party soon realised that they had mistaken his character; for he contested the papal right of investiture even more resolutely than his father had done, and as early as 1110 he undertook a brilliant expedition to Rome in connection with the matter. When he reached Lombardy and held a diet of the empire on the plains of Roncaglia near Piacenza, the Italian cities (with the exception of Milan and Pavia), which had risen more rapidly than those of Germany and to a height of prosperity even greater, acknowledged his supremacy and the countess Matilda did him homage as her feudal lord. In the year 1111 he arrived at Rome.
[1111-1122 A.D.]
The quarrel with Pope Paschal II had broken out afresh over the question of his coronation and the investiture, but at length the disputants came to an agreement to the effect that the emperor should renounce the right of investiture and that the pope should prevail upon the lords spiritual to resign all temporal dominion in the empire. The pope then led the king to St. Peter’s, according to ancient usage, amidst hymns of praise and great rejoicings. Henry, however, had already surrounded the cathedral by Germans. When the bishops refused the renunciation required of them, and the emperor consequently demanded full rights of investiture, the pope was in doubt as to whether he should proceed with the coronation under these circumstances. One of Henry’s retinue cried impatiently: “What need of so many words? It is the will of my lord the king to be crowned as Charlemagne was!”
From that moment the pope and his cardinals were prisoners. Henry carried the former off with him, in spite of a furious tumult at Rome, through which he and his knights cut their way with the sword. But the spirit of Gregory VII lived on in the church; when the pope, his spirit broken by confinement, granted the king the right of investing bishops and abbots, and actually crowned Henry after his release from prison, the cardinals and the French clergy excommunicated the emperor and continued the conflict with their ghostly weapons. Meanwhile Henry V had returned to Germany, where fortune still smiled upon him; for at Warnstedt, to the north of the Harz, his general Hoyer von Mansfeld defeated the Saxon and Thuringian nobles, with Ludwig der Springer, “the jumper,” and Wiprecht von Groitzsch among them, who had risen in revolt against the imperial house with their old stubborn defiance (1113).
The emperor, who had just concluded a brilliant marriage with Matilda of England, was now at the height of his power; but he nevertheless did not succeed in permanently establishing the royal authority in North Germany, where the Saxons in particular were constantly striving to secure a more independent position. When Henry was on an expedition against the Frisians, the city of Cologne rebelled, and the princes of the lower Rhine entered into alliance with it. Henry’s good fortune deserted him before its walls; and his enemies lifted their heads on all sides. By his action in imprisoning Count Ludwig of Thuringia he had incurred the violent resentment of the Saxon and Thuringian nobles. They arose afresh in rebellion, and this time they defeated the emperor at Welfesholze near Mansfeld in the Harz (1115). The whole of North Germany and almost the whole of the German church fell away from him; in South Germany, on the contrary, his nephew, Friedrich von Staufen, duke of Swabia, remained loyal to the imperial cause, as did Bavaria under Welf.
Henry himself had gone to Italy again (1116-1118), another cause of quarrel having been added to the War of Investiture, which still dragged on. Countess Matilda was dead, and had bequeathed all her lands and goods to the holy see. A great part of the land, however, was held as a fief of the empire, and should therefore have reverted to the king on her death without issue; and Henry further laid claim to her
