Counts of Celje
About 600 the valley was settled by Romanised Celts backing away from the migration of Alpine Slavs moving up the Drava Valley. Part of the Upper Carinthian "Lurngau", the estates from about 1135 were held by the local Counts of Ortenburg. After the extinction of the Ortenburg dynasty in 1418, their inheritance passed to the Counts of Celje and finally to the Habsburg dukes of Carinthia in 1456.
