In 872, the cult of Dagobert was brought to life (or revived) by Charles the Bald, king of West Francia (840–877), who had his relics translated to a specially built basilica in Stenay staffed with its own canons. The timing seems to indicate that Charles was trying to establish himself in that part of Lotharingia that he had only acquired in 870 by the Treaty of Meerssen. The translation of the relics is mentioned in the "Life of Dagobert" and in a charter preserved in the cartulary of the Abbey of Gorze, which provides the date.
