New research suggests Charlemagne’s military campaigns in the late 700s were instrumental in establishing the cultural and political divide between Eastern and Western Europe. Historian Helmut Reimitz’s study, published in the Austrian History Yearbook, focuses on Charlemagne’s conquest of the Avars, a nomadic group inhabiting modern-day Hungary. This campaign, according to the research, wasn’t simply a territorial expansion but a foundational moment in defining Europe’s future trajectory. The conquest led to the imposition of Frankish political and legal structures, solidifying a western sphere of influence. Conversely, areas beyond this expansion remained distinct, fostering the development of different political and cultural identities. The study argues this 8th-century event had lasting consequences, shaping the continent’s landscape for over a millennium. Reimitz’s work offers a new perspective on the origins of Europe’s enduring east-west divisions.
