Chlothar IV, a monarch of the Merovingian dynasty, ascended to the throne of Austrasia in the year seven hundred seventeen, following the strategic maneuvers of Charles Martel. His reign marked a significant division in the kingdom of the Franks, as he was installed in opposition to Chilperic II, who retained control over Neustria. This division was the first since six hundred seventy-nine, highlighting the political complexities of the time.
Chlothar's reign, though brief, was characterized by military engagements and political intrigue. His elevation to kingship was a calculated move by Charles Martel, who sought to legitimize his position as mayor of the palace after his victory at the Battle of Vincy. This battle not only solidified Charles's control over Austrasia but also allowed him to raise a larger army through royal summons, thereby expanding his military resources.
During Chlothar's rule, significant events unfolded, including the promulgation of the Lex Alamannorum, a law code for the Alamanni, which was issued in his name. However, the exact dates of his reign remain uncertain, with historical documents suggesting he ruled between twenty-eight June seven hundred seventeen and eighteen May seven hundred eighteen. The ambiguity surrounding his parentage and the legitimacy of his claim to the throne has led to speculation about his role as a potential puppet king.
Chlothar IV's reign came to an abrupt end, likely between twenty-four February and eighteen May seven hundred eighteen. His death prompted a swift political shift, as the kingdom was reunited under Chilperic II. The circumstances surrounding his demise have led to theories of foul play, particularly given the timing of his death in relation to Charles Martel's ambitions. Despite the uncertainties, Chlothar IV remains a notable figure in the history of the Frankish monarchy.
