He was the eldest son of KingClovis II, and his queenBalthild and succeeded his father under the regency of his mother.[2] Only a month beforehand, according to the near-contemporaryLife of Eligius by the courtierAudoin (bishop) of Rouen,Saint Eligius had prophesied the death of Clovis, Balthild's downfall, and Chlothar's short reign.[3]
Few things are known about the time of Chlothar's reign. TheHistoria Langobardorum reports that in the early 660s a Frankish army invaded Provence and then Italy.[4] This force came upon the camp of theLombard kingGrimoald I of Benevento, at Rivoli near Asta. Grimuald pretended to flee. The Franks looted the camp and celebrated. Then, after midnight, Grimuald attacked and drove them back to Neustria.
After the death ofSaint Eligius in 661, theLife of Eligius records that a plague reduced the population of France's cities.[5] A plague in the British Isles, according toBede, did the same there in 664.[6]
During the regency,Austrasians requested a king of their own and, in 662, Chlothar's court sent another son of Clovis II,Childeric II, to be king there.[7]
Also during his reign, themayor of the palaceErchinoald died and a council of Franks electedEbroin to replace him. Ebroin's early administrative authority was significant:Bede tells the story of how, in 668, the newly appointed Theodore of Canterbury could only travel through the Frankish kingdoms from Rome with the mayor's permission.[8] Chlothar may have been more politically active after this time, as he reached the age of majority in 669. The nearest contemporary chronicle, theLiber Historiae Francorum of 727, relates only that he ruled for four years (presumably a reference to his active years 669–673) and then died. He is confirmed as still being in the sixteenth year of his reign in a chronological note in a Victorian Easter table of 673.[9] His brotherTheuderic III succeeded him as king later that same year.
