572 or 573), king of the Lombards, and conqueror of Italy, succeeded his father Audoin about 565.
On Walthari's death (about 546 ?) Audoin succeeded.
A large force of Lombards under Audoin fought on the imperial side at the battle of the Apennines against the Ostrogothic king Totila in 5 53, but the assistance of Justinian, though often promised, had no effect on the relations of the two nations, which were settled for the moment after a series of truces by the victory of the Langobardi, probably in 554.
The resulting peace was sealed by the murder of Ildichis and Ustrogotthus, and the Langobardi seem to have continued inactive until the death of Audoin, perhaps in 565, and the accession of his son Alboin, who had won a great reputation in the wars with the Gepidae.
