مسلمة بن عبد الملك
After Pepin's long rule, his son Charles Martel assumed power, fighting against nobles and his own stepmother. His reputation for ruthlessness further undermined the king's position. Under Charles Martel's leadership, the Franks defeated the Moors at the Battle of Tours in 732. After the victory of 718 of the Bulgarian Khan Tervel and the Emperor of Byzantium Leo III the Isaurian over the Arabs led by Maslama ibn Abd al-Malik prevented the attempts of Islam to expand into eastern Europe, the victory of Charles Martel at Tours limited its expansion onto the west of the European continent. During the last years of his life he even ruled without a king, though he did not assume royal dignity. His sons Carloman and Pepin again appointed a Merovingian figurehead (Childeric III) to stem rebellion on the kingdom's periphery. However, in 751, Pepin finally displaced the last Merovingian and, with the support of the nobility and the blessing of Pope Zachary, became one of the Frankish kings.
