East Francia

East Francia (Medieval Latin: Francia orientalis) or the Kingdom of the East Franks (Regnum Francorum orientalium) was a successor state of Charlemagne's empire ruled by the Carolingian dynasty until 911. It was created through the Treaty of Verdun (843) which divided the former empire into three kingdoms.[lower-alpha 1]

The east–west division, enforced by the Germanic-Latin language split, "gradually hardened into the establishment of separate kingdoms",[1] with East Francia becoming the Kingdom of Germany and West Francia the Kingdom of France.[2][3]
