king of Ireland, lived in the 6th century. He ascended the throne about 565, was removed by Colman, son of Dermod, and, vanquished and pursued, he took refuge in a monastery governed by Columba, who afterwards became a Pictish disciple. But even here he was pursued and massacred. Columba, indignant at the violation of the sacred place, demanded vengeance, and raised a crusade which resulted in the death of Colman. The successor of Baodan was Hugh II, or Aodh, son of Immeric. See Hoefer, Nouv. Biog. Generale, s.v.
