West Francia, also known as the West Frankish Kingdom or Francia Occidentalis, was a short-lived kingdom. It was the lands of the western part of the Carolingian Empire. They came under the control of Charlemagne's grandson, Charles the Bald, as a result of the Treaty of Verdun of 843.
The Frankish Empire was the great realm united by Charlemagne that was a large part of Western Europe. It was split after a three-year-long civil war between his grandsons (840-843). Charles the Bald and his half-brother Louis the German went against his brother Lothair I.
The Carolingian Empire of the Franks founded by their grandfather lasted only one generation through their father Louis the Pious. His realm was split into East Francia, West Francia or the Western Realm, and Middle Francia. The West Frankish Kingdom is the start of both medieval France and modern France.
