White Croatia and the Arrival of the Croats: An Interpretation of Constantine Porphyrogenitus on the Oldest Dalmatian History

The article examines Constantine Porphyrogenitus' (913–59) witness on the arrival of the Croats in Dalmatia during the seventh century. The emperor's narrative proposes a migration from a land called White Croatia, located somewhere in central Europe, and a battle with the Avars in order to secure their new territory. The migration, although becoming an important element in nationalist thought, is not confirmed by any other source, neither contemporary, nor later, being reported only by Constantine. I propose that the migration was instead a literary pattern deployed by the emperor in order to explain the complex developments which brought a new elite, called Croats, to a leading position in tenth‐century Dalmatia.
