Chilperic II
Chlothar IV (died 718) was the king of Austrasia from 717 until his death. He was a member of the Merovingian dynasty, and was installed by Charles Martel, a contender for the office of mayor of the palace, in opposition to Chilperic II, whose rule was thereby restricted to Neustria. This marked the first time since 679 that the kingdom of the Franks was divided. Following Chlothar's death, it was reunited under Chilperic.
