'Adalbero of Eppenstein' (
980 –
November 29 1039) was
Duke of Carinthia from
1011 or
1012. He succeeded the
Salian Conrad I.
After political altercations with the Salians and an unsuccessful rebellion against the
Holy Roman Emperor Conrad II, Adalbero was forced to renounce all his offices and fiefdoms, but
Egilbert, Bishop of Freising, a councillor to Conrad's son
Henry, advised the princes of Germany and Henry himself, who had been elected king, to not recognise the deposition. Conrad was required to perform much begging before Henry consented to the act and Adalbero was removed. He died in exile in
1039.
Adalbero was married to Beatrix (died
February 23 after
1125), a daughter of
Herman II, Duke of Swabia, a
Conradine.
