Pepin of Herstal, Frankish statesman (b. 635)
Pepin II (c. 635 – 16 December 714), commonly known as Pepin of Herstal, was a Frankish statesman and military leader who de facto ruled Francia as the Mayor of the Palace from 680 until his death. He took the title Duke and Prince of the Franks upon his conquest of all the Frankish realms.
The son of the powerful Frankish statesman Ansegisel, Pepin worked to establish his family, the Pippinids, as the strongest in Francia. He became Mayor of the Palace in Austrasia in 680. Pepin subsequently embarked on several wars to expand his power. He united all the Frankish realms by the conquests of Neustria and Burgundy in 687. In foreign conflicts, Pepin increased the power of the Franks by his subjugation of the Alemanni, the Frisians, and the Franconians. He also began the process of evangelisation in Germany.
Pepin's statesmanship was notable for the further diminution of Merovingian royal authority, and for the acceptance of the undisputed right to rule for his family. Therefore, Pepin was able to name as heir his grandson Theudoald. But this was not accepted by his powerful son Charles Martel, leading to a civil war after his death in which the latter emerged victorious.
