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.
