Conrad summoned Adalbero to court at Bamberg on 18 May 1035, to answer an indictment of treason for his actions regarding Hungary. In the presence of the German dukes, Conrad demanded that Adalbero be stripped of all his titles and lands. The dukes hesitated and demanded that Conrad's son Henry, the Germany's co-King and Conrad's designated successor, join the assembly before a decision was made. Henry refused to depose Adalbero, citing an earlier agreement with Adelbero to be his ally in negotiating a settlement between him and his father. Conrad resorted to exhortations, pleas, and threats to convince Henry to support Adalbero's deposition. Henry's support was soon followed by that of the other dukes. Conrad then ordered Adalbero to be removed as Duke and sentenced him and his son to exile. After attacking Conrad's allies in Carinthia, Adalbero fled to his mother's estates in Ebersberg in the Duchy of Bavaria, where he remained until his death in 1039. The duchy of Carinthia remained unoccupied until February 2, 1035, when Conrad named his cousin Conrad the Younger as the new duke. With the appointment, the three southern German duchies of Swabia, Bavaria, and Carinthia were all under the control of Emperor Conrad through his family members (his stepson Herman in Swabia, his son Henry in Bavaria, and his cousin Conrad in Carinthia).
