Verdun
Verdun ("Verodunum", a latinisation of a place name meaning "strong fort") was founded by the Gauls. It has been the seat of the bishop of Verdun since the 4th century, with interruptions.. In 486, following the decisive Frankish victory at the Battle of Soissons, the city (amongst several other nearby cities) refused to yield to the Franks and was thus besieged by King Clovis I. The 843 Treaty of Verdun divided Charlemagne's empire into three parts.
