Middle Francia
The Carolingian empire would eventually include France, Germany, northern Italy and much of Western Europe. In 843, the Frankish empire was divided into three parts, giving rise to West Francia in the west, East Francia in the east, and Middle Francia in the centre. Most of what is today the Netherlands became part of Middle Francia; Flanders became part of West Francia. This division was an important factor in the historical distinction between Flanders and the other Dutch-speaking areas.
