Others again, sought to exercise the power in their own name both against the king and against the great nobles - such as Ebroin (in Neustria), and, later, the Carolingians Pippin II., Charles Martel, and Pippin III., who, after making use of the great nobles, kept the authority for themselves.
But in spite of a very firm policy Ebroin was unable to maintain this unity, and while Clotaire III., son of Clovis II., reigned in Neustria and Burgundy, he was obliged in 660 to give the Austrasians a special king, Childeric II., brother of Clotaire III., and a special mayor of the palace, Wulfoald.
He endeavoured to maintain at any rate the union of Neustria and Burgundy, but the great Burgundian nobles wished to remain independent, and rose under St Leger (Leodegar), bishop of Autun, defeated Ebroin, and interned him in the monastery of Luxeuil (670).
In the same year, taking advantage of the general anarchy, Ebroin and Leger left the cloister and soon found themselves once more face to face.
Each looked for support to a different Merovingian king, Ebroin even proclaiming a false Merovingian as sovereign.
After his death Ebroin became sole and absolute ruler of the Franks, imposing his authority over Burgundy and subduing the Austrasians, whom he defeated in 678 at Bois-du-Fay, near Laon.
