Troubles presently began to ferment; here and there in Saxony a rumour ran of attempts on the young king’s life. Agnes was soon forced to make large concessions in order to gain friends, who proved untrustworthy after all. A Saxon noble, Otto, of the family of Nordheim, a race akin to the Billings, whose hereditary seat lay close to the modern town of Göttingen, received from the empress the duchy of Bavaria, which Henry III had acquired for his own house. Rudolf von Rheinfelden, a Burgundian noble, worked his way into the empress’ good graces, and received the duchy of Swabia together with the hand of the daughter of the empress. The duchy of Carinthia was given to Berthold, a Zähringian. If only the empress could have purchased fidelity by these concessions! But not one of these men was trustworthy; and the moving spirit of all the plots which aimed at wresting the sovereign power from the empress and bestowing it on the nobles of the empire, was Archbishop Hanno of Cologne, a man of low origin, but ambitious, harsh, crafty, and cunning, although outwardly wearing the semblance of the sanctity of the cloister. It was natural that the power of the empire should decline abroad—in Italy, in Hungary, and over the Wends; and the fact was laid to the charge of the empress, together with the accusation that she was bringing up her son too effeminately. In brief a criminal project was maturing in Hanno’s heart as in the hearts of the princes, his allies. The empress was then at Kaiserwerth on the Rhine with her twelve-year-old son, when Hanno appeared at her court, and after a festive banquet invited the young king to take an excursion on the Rhine in his beautiful boat. The boy embarked unsuspectingly with Hanno, together with some of the conspirators: the bishop’s serfs plied their oars and the boat was quickly under way. The lamentations of the young king’s mother pursued him from her balcony; the people followed on the banks, cursing the robbers; and the boy himself, alarmed and fearing the worst, jumped into the river, from which he was rescued with difficulty. But the plot had succeeded and Hanno, who now had the young king in his own hands, succeeded, by the help of the nobles, in assuming the reins of power at the head of the bishops.
Matters were not thereby mended in the empire. The empress soon retired from the world and ended her days in Italy, occupied in works of piety. Under Hanno’s administration any man who pleased laid hands on the royal demesnes; and a few years later the young king was an eye-witness of mortal combat in the cathedral at Goslar, where brawling ecclesiastics fought for temporal honours in the very sanctuary.
Such an education sowed the seeds of mistrust, bitterness, and hatred in the heart of the young ruler, and as soon as he was able he threw himself into the arms of a different guide, Archbishop Adalbert of Bremen. The latter, no less ambitious than Hanno, and even prouder, sought to exalt his famous metropolitan see, whence missions still went forth across the North Sea and the Baltic, to the position of the patriarchate of the north. Formerly the friend of Henry III, he now sought to win the friendship of the youthful Henry IV. When Henry attained the age of sixteen he declared him of age, according to German law, by girding him with the sword, but for some years he continued to direct his unripe youth. In his endeavours Adalbert frequently incurred the displeasure of the Saxon nobles. Their intentions, as a matter of fact, were evil, and it was against them that he fostered the young king’s suspicions. Meanwhile the latter began to grow up to independent manhood. Of the authority, property, and prerogatives of his predecessors, he found but little left; all his efforts were directed to their recovery, and in pursuit of this end he manifested the iron will of his forefathers. Their hot blood flowed also in his veins, inciting him to occasional arbitrary acts, and above all to excesses which were magnified by the slanderous tongues of his enemies. He first sought to subdue Saxony. The means he employed for the purpose were such as the Normans had adopted in lower Italy; he erected strongholds in commanding situations in the land. From these centres, however, many acts of violence were perpetrated in the surrounding country, and he thus aroused the wrath, not only of individual nobles, but of the whole Saxon race.
