Also in 632, the nobles of Austrasia revolted under the mayor of the palace, Pepin of Landen. In 634, Dagobert appeased the rebellious nobles by putting his three-year-old son, Sigebert III, on the throne, thereby ceding royal power in the easternmost of his realms, just as his father had done for him eleven years earlier. In historian Ian Wood's view, Dagobert's creation of a sub-kingdom for his son Sigibert had "important long-term implications for the general structure of Merovingian Francia."
