Charlemagne and his sons crushed the Avar Khaganate by the end of the 8th century, but the Franks failed to replace the vacuum of power the Avars left in the region of the Great Plain of Pannonia, so after a century of political and cultural fragmentation among different powers (Franks, Slavs, Bulgars...) it was finaly open for the Magyar invasion by the early 10th century.
What would have happened if the Franks would have opted for a major settlement of the rather underpopulated Pannonian plain, boosting the migration of Franks and other Christian subdits of the Empire for establishing proper cities, abbeys and monasteries in the area? Could have this blocked the expansion fo the Bulgars first and the Magyars later? Which could have been the impact of a Germanized Great Pannonia (and the absence of Hungary) in the later developments of the Middle Ages?
