Putting off, therefore, the subjugation of the rebellious Slavs, Conrad immediately set everything in readiness for his expedition into Italy. He first convoked a diet at Augsburg, had his son Henry elected successor to his throne, and yielding to his wife’s persuasions was reconciled to his stepson, Duke Ernst of Swabia. This took place in 1026, and in the same year the German army made its appearance in Italy. Pavia was first invested, and repeated attempts were made to take it by storm; but the brave citizens victoriously repulsed every assault, and Conrad was reduced to great straits. This so enraged him that, goaded to fury, he savagely devastated the surrounding country. The German king gained little by these cruelties, and as in spite of his victory he suffered great loss at the taking of Ravenna, he might have been compelled to retreat ingloriously from Italy if his political astuteness had not come to his aid. He succeeded in bringing the king of Burgundy, on whose assistance the Lombards relied, over to his own side. Rudolf came to Italy in person to be present at Conrad’s coronation as emperor, and the courage of the inhabitants of the invaded country sank so low that even Pavia surrendered, and Conrad was acknowledged king of Lombardy. He then received the imperial crown at the hands of Pope John XIX, on the 26th of March, 1027; and after making some provisions for the pacification of Lombardy he hastened back to Germany, where in the meanwhile his presence had become extremely necessary.
In spite of the show of reconciliation, Duke Ernst of Swabia was meditating open rebellion. Conrad was well informed of the plans of the conspirators, though the secret had been carefully guarded; and therefore, after crossing the Alps, he proceeded with all haste to Ratisbon to make preparations for subduing the threatened revolt. Conrad’s plans on this occasion strikingly display his practical ability and clear-sightedness. During his absence in Italy the ducal office had become vacant in Bavaria by the death of Henry, and the king endeavoured to procure it for his own family. In view of the encroachments of the great nobles, who amassed vast wealth at the expense of the empire, this would have profited him little unless he could increase the ducal revenue at the same time. Consequently, having succeeded in getting his ten-year-old son Henry appointed duke of Bavaria, Conrad instituted a strict inquiry into the condition of the property of the empire in that province, and restored to the crown much that had been usurped by bishops and counts. By this measure the king really struck at the root of the evil. Decrees could do little to cement the unity of the empire; what it needed was to be provided with a material basis. And of this, the most necessary element in the condition to which the empire had come was the creation of a revenue which should make the head of the state independent of the accidents of private fortune for the maintenance of his authority.
The kings commonly made the mistake of trying to gain the adherence or friendship of the great nobles by presents made at the expense of the property of the empire; and therefore Conrad II acted not only wisely but honourably when, amidst the greatest dangers, he adopted the opposite course; for it was nobler to perish than to reduce the office of head of the state to a shadow, by purchasing the favour of the great nobles. The salutary effect of his firmness was quickly manifest; for after he had gained his object in Bavaria the king took vigorous measures to put an end to the agitation in Swabia. For this purpose he promptly convened a diet at Ulm to sit in judgment upon Duke Ernst in Alamannia. The duke collected an army and marched against the king, but the firm attitude of the latter had already made a great impression upon the nobles. Two counts deserted the duke, others of the conspirators followed, and within a short time Ernst’s forces were so diminished that he was obliged to submit to the king’s mercy. Conrad had his stepson conveyed in custody to the fortress of Giebichenstein near Halle, and then reduced the whole of Swabia to allegiance to the head of the empire. These proceedings added greatly to his reputation, open and secret foes now courted the king’s favour, and by the fifth year of his reign Conrad II had materially increased the authority of the empire.
