1054.
Leo IX., in 1054, marched against the Normans who were threatening the southern border of the Roman territory, but was defeated and taken prisoner. The victors treated him with all possible reverence, and he soon saw the policy of making friends of such a bold and warlike people. A treaty of peace was concluded, wherein the Normans acknowledged themselves dependents of the Papal power: no notice was taken of the fact that they had already acknowledged that of the German-Roman Emperors. This event, and the increasing authority of his old enemy, Godfrey, in Tuscany, led Henry III. to visit Italy again in 1055. Although he held the Diet of Lombardy and a grand review on the Roncalian plains near Piacenza, he accomplished nothing by his journey: he did not even visit Rome. Leo IX. died the same year, and Henry appointed a new Pope, Victor II., who, like his predecessor, became an instrument in the hands of Hildebrand of Savona, a monk of Cluny, who was even then, although few suspected it, the real head and ruler of the Christian world.
The Emperor discovered that a plot had been formed to assassinate him on his way to Germany. This danger over, he had an interview with king Henri of France, which became so violent that he challenged the latter to single combat. Henri avoided the issue by marching away during the following night. The Emperor retired to his palace at Goslar, in October, 1056, where he received a visit from Pope Victor II. He was broken in health and hopes, and the news of a defeat of his army by the Slavonians in Prussia is supposed to have hastened his end. He died during the month, not yet forty years old, leaving a boy of six as his successor.
1062. HENRY IV.
The child, Henry IV., had already been crowned King of Germany, and his mother, the Empress Agnes, was chosen regent during his minority. The Bishop of Augsburg was her adviser, and her first acts were those of prudence and reconciliation. Peace was concluded with Godfrey of Lorraine and Baldwin of Flanders, minor troubles in the States were quieted, and the Empire enjoyed the promise of peace. But the Empress, who was a woman of a weak, yielding nature, was soon led to make appointments which created fresh troubles. The reigning princes used the opportunity to make themselves more independent, and their mutual jealousy and hostility increased in proportion as they became stronger. The nobles and people of Rome renewed their attempt to have a share in the choice of a Pope; and, although the appointment was finally left to the Empress, the Pope of her selection, Nicholas II., instead of being subservient to the interests of the German Empire, allied himself with the Normans and with the republican party in the cities of Lombardy.
At home, the troubles of the Empress Agnes increased year by year. A conspiracy to murder the young Henry IV. was fortunately discovered; then a second, at the head of which was the Archbishop Hanno of Cologne, was formed to take him from his mother's care and give him into stronger hands. In 1062, when Henry IV. was twelve years old, Hanno visited the Empress at Kaiserswerth, on the Rhine. After a splendid banquet, he invited the young king to look at his vessel, which lay near the palace; but no sooner had the latter stepped upon the deck, than the conspirators seized their oars and pushed into the stream. Henry boldly sprang into the water; Count Ekbert of Brunswick sprang after him, and both, after nearly drowning in their struggle, were taken on board. The Empress stood on the shore, crying for help, and her people sought to intercept the vessel, but in vain: the plot was successful. A meeting of reigning princes, soon afterwards, appointed Archbishop Hanno guardian of the young king.
He was a hard, stern master, and Henry IV. became his enemy for life. Within a year, Hanno was obliged to yield his place to Adalbert, Archbishop of Bremen, who was as much too indulgent as the former had been too rigid. The jealousy of the other priests and princes was now turned against Adalbert, and his position became so difficult that in 1065, when Henry IV. was only fifteen years old, he presented him to an Imperial Diet, held at Worms, and there invested him with the sword, the token of manhood. Thenceforth Henry reigned in his own name, although Adalbert's guardianship was not given up until a year later. Then he was driven away by a union of the other Bishops and the reigning princes, and his rival, Hanno, was forced, as chief counsellor, upon the angry and unwilling king.
1066.
The next year Henry was married to the Italian princess, Bertha, to whom his father had betrothed him as a child. Before three years had elapsed, he demanded to be divorced from her; but, although the Archbishop of Mayence and the Imperial Diet were persuaded to consent, the Pope, Alexander II., following the advice of his Chancellor, Hildebrand of Savona, refused his sanction. Henry finally decided to take back his wife, whose beauty, patience and forgiving nature compelled him to love her at last. About the same time, his father's enemy and his own, Godfrey of Lorraine and Tuscany, died; another enemy, Otto, Duke of Bavaria, fell into his hands, and was deposed; and there only remained Magnus, Duke of the Saxons, who seemed hostile to his authority. The events of Henry's youth and the character of his education made him impatient and mistrustful: he inherited the pride and arbitrary will of his father and grandfather, without their prudence: he surrounded himself with wild and reckless princes of his own age, whose counsels too often influenced his policy.
No Frank Emperor could be popular with the fierce, independent Saxons; but when it was rumored that Henry IV. had sought an alliance with the Danish king, Swen, against them,—when he called upon them, at the same time, to march against Poland,—their suspicions were aroused, and the whole population rose in opposition. To the number of 60,000, headed by Otto, the deposed Duke of Bavaria (who was a Saxon noble), they marched to the Harzburg, the Imperial castle near Goslar. Henry rejected their conditions: the castle was besieged, and he escaped with difficulty, accompanied only by a few followers. He endeavored to persuade the other German princes to support him, but they refused. They even entered into a conspiracy to dethrone him; the Bishops favored the plan, and his cause seemed nearly hopeless.
