Childebert I was a Frankish King of the Merovingian dynasty, as third of the four sons of Clovis I who shared the kingdom of the Franks upon their father's death in 511. He was one of the sons of Saint Clotilda, born at Reims.
He reigned as King of Paris from 511 to 558 and Orléans from 524 to 558.
In the partition of the realm, he received as his share the town of Paris, the country to the north as far as the river Somme, to the west as far as the English Channel, and the Armorican peninsula (modern Brittany). His brothers ruled in different lands: Theuderic I in Metz, Chlodomer in Orléans, and Clothar I in Soissons.
He died on 13 December 558, and was buried in the abbey he had founded, where his tomb has been discovered. St-Germain-des-Prés became the royal necropolis for the Neustrian kings until 675. He left no sons, only two daughters, Chrodoberge and Chrodesinde, by his wife Ultragotha.
