Adalbero I of Metz was an important member of the clergy during the middle years of the tenth century, serving as Bishop of Metz from 929 till 954. He also became Abbott of Sint-Truiden in 944: he presided over a period of overdue rebuilding and expansion of a monastery which had been devastated by Normans during the closing decades of the previous century.
Names
Sources also sometimes identify him as Adalbro of Bar or as Adalbro of The Ardennes.
In 929 Adalbero was elected by the clergy and the people to succeed whose own episcopal term had recently ended badly. As Bishop of Metz, Adalbero's enthusiastic promotion of a revival in monasticism gained him the soubriquet "father of the monks". He encouraged the rebuilding of monastic buildings that had fallen into disrepair during preceding decades and the expansion of monastic properties. Starting in 933/934 he became a driving force behind the revival of Gorze Abbey, appointing the energetic Abbot John to lead the project on site. Gorze then became a famous exemplar for similar monastic recoveries elsewhere in the region during the middle and later years of the tenth century. In 941 he expelled the canons from the Abbey of Saint-Arnould in Metz, and replaced them with monks imported from Gorze, who lived according to the Rule of Saint Benedict under their new abbot, Héribert. It is recorded that Adalbero later returned to Archbishop Bruno of Cologne, the piece of St Peter's ferula, a treasured relic which had been sent across to Metz at the time of the Hunnishinvasions. It is possible that Adelbero was relieved of his duties as Bishop of Metz by Duke Conrad the Red in 954, leaving him free to concentrate on his duties at Sint-Truiden until his death in 962. On the other hand, Duke Conrad was killed in battle in 955, and there are no indications of any successor bishop having been appointed at Metz till after Adalbero's death.
Abbot
In 944 Adalbero expelled Abbot Reinier from Sint-Truiden Abbey on account of the latter's "poor conduct", and was himself elected Abbott of Sint-Truiden in Renier's stead. Although he retained his episcopal title till his death, it seems that from the middle 940s he tried to divide his duties equally between the two locations. At Sint-Truiden the Abbey was almost entirely rebuilt, now on a very grand scale. Monasteric lands that had been usurped by local nobility were restored, as was monastic observance. In 947 he was able to consecrate the new abbey church.
Politics
In the wars that divided Louis IV of France and Otto I of Germany in the 930s, Adalbero took the side of Louis in the contest to determine which of these heirs of Charlemagne should have control over Lorraine. He energetically defended his episcopal city from the German armies. However, when the belligerents concluded their differences in 939 he was obliged to open the gates of Metz to soldiers from the Ottonian side. In 950 Adalbero intervened as a mediator in the conflict between Louis IV of France and Hugh, Count of Paris. In 968, several years after Adalbero's death, the emperor mentioned Adalbero in a charter in which he described Adalbero using the adjective "sanctissimus". The fact that Adalbero's memory was cherished by Emperor Otto adds weight to the suspicion that any removal of his rights and duties as Bishop undertaken by Duke Conrad the Red in 954 is unlikely to have been permanent.
Death
According to the episcopal records at Metz Adalbero died on 26 April 962. Records at Sint-Truiden give his date of death as 23 February 964. There are also old history books giving the year of his death as 960. His body was taken to Gorze and then to the Abbey of Saint-Arnould in Metz where it became the object of much veneration.
