Conrad III, Duke of Carinthia

He was son of Hezzelin I, count in the Zülpichgau,^[2] and brother of Count palatine Henry I of Lotharingia. His mother possibly was a daughter of the late Salian duke Conrad I of Carinthia.^[2]

In 1055 he had joined the rebellion of his Ezzonid cousin Duke Conrad I of Bavaria and Duke Welf of Carinthia against Emperor Henry III. Nevertheless, upon Henry's death in 1056, he was pardoned by his widow Agnes of Poitou and enfeoffed with the Carinthian duchy. Conrad, however, did not succeed in imposing his authority on the powerful native aristocracy. He died five years later, having possibly never entered Carinthia. He was succeeded by the Zähringen duke Berthold II.
