handing over of the golden sceptre, received back the kingdom of Lombardy as a fief of the German crown. But Duke Henry had his reward for his consistent loyalty at Berengar's expense: the marches of Aquileia and Verona were added to the Bavarian dukedom.
Up to this point there had been no overt act of rebellion on the part of the conspirators. Liudolf and the Archbishop of Mayence had been present at the Augsburg diet; indeed the latter had taken a leading part in the ecclesiastical business transacted there. But as the rebellion matured, the causes of discontent increased. The marked displeasure of Otto at Conrad's management of the affairs of Italy had driven the Duke of Lorraine into the ranks of the malcontents. The appointment of the king's brother Bruno to the post of archchancellor of Italy was an additional grievance to Archbishop Frederick, who had counted upon that dignified sinecure for himself. Whereas Henry had gained by the settlement at Augsburg, Liudolf had received no share in the spoils. Possibly the birth of a child to Adelaide, a boy named Henry who died in infancy, at the end of the year 952, was the decisive event, which determined the outbreak of hostilities.
Otto appears to have been blind to the dangers which surrounded him. It was only while journeying to Ingelheim on his return from Alsace, whither he had gone to visit his wife's relations, that he realised the critical state of affairs. Judging it imprudent to keep the Easter festival, as he had purposed, at so isolated a place as Ingelheim, he turned aside to Mayence; but Mayence proved no less dangerous. He found the gates of the city closed against him and in an unseemly manner he was kept waiting until the Archbishop, who was absent from the city performing his Lenten devotions in retreat, returned to grant him admittance. Liudolf and Conrad also appeared on the scene, and the king was caught in a trap. The conspirators made haste to clear themselves of having any designs against their sovereign; but they acknowledged that it had been their intention to waylay Henry in the event of his coming to Ingelheim for the Easter festival. Even towards the king their attitude was not so peaceable as they had affirmed; by duress they extorted from him some sort of treaty, of which the terms are unrecorded, but the nature may be fairly conjectured. It was no doubt as advantageous to Liudolf as it was detrimental to the interests of Duke Henry. Liudolf was assured of the succession and possibly was even to have an immediate share in the government. Otto was glad to escape at any price. Nevertheless, once safe in Saxony he did not scruple to revoke the treaty. He summoned Liudolf and Conrad to appear before him and ordered them either to hand over their confederates or else to receive the punishment due for their offence. A diet for the discussion of their case was to meet at Fritzlar. The dukes did not present themselves at the diet; they were deprived of their dukedoms, and hostilities began in earnest.
