Pepin the Short
Childeric III (c. 717 – c. 754) was King of Francia from 743 until he was deposed by Pope Zachary in March 751 at the instigation of Pepin the Short. Although his parentage is uncertain, he is considered the last Frankish king from the Merovingian dynasty. Once Childeric was deposed, Pepin the Short, who was the father of emperor Charlemagne, was crowned king, initiating the Carolingian dynasty.
