Arpad's great-grandson, Prince Geiza, converted to Christianity and raised his son Istvan in the Christian spirit, for which he invited German missionaries. The wife of the young Istvan was the sister of the Bavarian king gisella (and herself, whose statue adorns the building of the music school in Uzhgorod).
Istvan I the Saint continued the work of Arpad, consolidating the Hungarians into a Christian power.
