Treaty of Verdun
The Treaty of Verdun (French: Traité de Verdun; German: Vertrag von Verdun), agreed to on 10 August 843, ended the Carolingian civil war and divided the Carolingian Empire between Lothair I, Louis II and Charles II, the surviving sons of the emperor Louis I. The treaty was the culmination of negotiations lasting more than a year. It was the first in a series of partitions contributing to the dissolution of the empire created by Charlemagne and has been seen as foreshadowing the formation of many of the modern countries of western Europe.
