カロリング朝
In 718, Charles Martel had Austrasian support in his war against Neustria for control of all the Francian realms. He was not king himself, but appointed Chlothar IV to rule in Austrasia. In 719, Francia was united by Martel's family, the Carolingian dynasty, under Austrasian hegemony. While the Frankish kings continued to divide up the Frankish realm in different ways over subsequent generations, the term Austrasia was only used occasionally after the Carolingian dynasty.
