Death of Pepin

When Pepin died in 714, however, the Frankish realm plunged into civil war and the dukes of the outlying provinces became de facto independent. Pepin's appointed successor, Theudoald, under his widow, Plectrude, initially opposed an attempt by the king, Dagobert III, to appoint Ragenfrid as mayor of the palace in all the realms, but soon there was a third candidate for the mayoralty of Austrasia in Pepin's illegitimate adult son, Charles Martel.

After the defeat of Plectrude and Theudoald by the king (now Chilperic II) and Ragenfrid, Charles briefly raised a king of his own, Chlothar IV, in opposition to Chilperic. Finally, at a battle near Soisson, Charles definitively defeated his rivals and forced them into hiding, eventually accepting the king back on the condition that he receive his father's positions (718). There were no more active Merovingian kings after that point and Charles and his Carolingian heirs ruled the Franks.

After 718 Charles Martel embarked on a series of wars intended to strengthen the Franks' hegemony in western Europe. In 718 he defeated the rebellious Saxons, in 719 he overran Western Frisia, in 723 he suppressed the Saxons again, and in 724 he defeated Ragenfrid and the rebellious Neustrians, ending the civil war phase of his rule. In 720, when Chilperic II died, he had appointed Theuderic IV king, but this last was a mere puppet of his. In 724 he forced his choice of Hugbert for the ducal succession upon the Bavarians and forced the Alemanni to assist him in his campaigns in Bavaria (725 and 726), where laws were promulgated in Theuderic's name. In 730 Alemannia had to be subjugated by the sword and its duke, Lantfrid, was killed. In 734 Charles fought against Eastern Frisia and finally subdued it.
