During world war II, the Hungarian government built a military defensive line in the North-Eastern Carpathians – the Arpad Line. It consisted of several belts. The first is in the Carpathian region, to protect the approaches to the main Carpathian watershed
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.
