The Frankish Kingdom was established in the 5th century by Merovech and expanded by his grandson Clovis. After Clovis' death, the kingdom was divided among his sons. Power later fell to the Mayors of the Palace, most notably Charles Martel, before Pippin the Short established the Carolingian dynasty in 751. Charlemagne conquered much of Western Europe and was crowned Holy Roman Emperor by the Pope in 800. His empire did not long survive his death and was divided among his grandsons in 843 by the Treaty of Verdun.
