Domitian of Carantania was a Slavic nobleman living in the principality of Carantania during the era of Charlemagne. He is remembered as a ruler who transitioned his people from paganism to Christianity. According to tradition, he founded the church at Millstatt Abbey following the tragic death of his son. While some historians once questioned his existence, archaeological findings of an epitaph mentioning his name and the era of Emperor Charlemagne suggest he was a real historical figure who served as a local leader under Frankish rule.
Life and legend


The legend states that after his son drowned in Lake Millstatt, Domitian ordered the waters to be drained to recover the body. He vowed to convert to Christianity and build a church at the site where his son was found. Following his baptism, he reportedly destroyed a thousand pagan statues, an event which some link to the etymology of the name Millstatt. He is believed to have been baptized in Salzburg during his youth.
Veneration


Domitian has been venerated since the early years of the Millstatt Abbey foundation. His remains were placed in a reliquary within the abbey church around 1130. He is commemorated as a saint, with his feast day observed on February 5. Historical records and liturgical calendars from the 12th century confirm his status as a figure of devotion at the site.
