Cadolah of Friuli

Cadolah (or Cadalaus) (also Cadolach, Chadalhoh or Chadolah) (died 819) was the Duke of Friuli from 817 to his death. He was a son of Count Berthold (Pera[h]told) and an Ahalolfinger.

He was a patron of the monastery of Saint Gall. With his brother Uuago, he donated property in the village of Wanga to the monastery by charter dated 23 October 805. He also donated property on 17 November 817, at which time he bore the title "count" (comis) and directed his son, Berthold, to make donations in his name after his death.

By then he had been put in charge of Dalmatia, where he was the local ruler at the time when an embassy from Constantinople passed through on their way to the court of Louis the Pious (816). Sometimes after that, probably in 817, he was created Duke of Friuli. Einhard calls him Cadolaum comitem et marcæ Foroiuliensis præfectum ("Cadolah, count and prefect of the Friulian march") in 818. Einhard later calls him dux Foroiuliensis when recording his death after returning from a campaign against Ljudevit Posavski in 819. According to the Vita Hludowici imperatoris, Cadolah was replaced by Baldric.
