[4] In 1045, King Henry III, nominated Adalbero successor to Bruno as Bishop of Würzburg.

He brought the monk Egbert from Gorze, who proved extremely effective firstly in bringing about the renewal of Münsterschwarzach Abbey and then, through the spread of the subsequent Münsterschwarzach Reforms, in exerting an influence far beyond it, from Harsefeld Archabbey [de] near Stade in the north to Melk.

In 1057 Adalbero re-settled the abbey of St. Peter, Paul and Stephen in Würzburg, until then a college of Canons Regular, with Benedictines from Münsterschwarzach.

In the Investiture controversy which broke out shortly afterwards, Adalbero took the side of Pope Gregory VII in opposition to Henry IV.

[1] Gregory objected to the practice of the appointment of bishops being vested in territorial princes rather than in the papacy.

In 1088 Adalberone renounced his episcopal dignity and dedicated the monastery of Komburg, near Schwabisch Hall, in Württemberg.

[6] In the "Neumünsterkirche" in Würzburg since 1948 there has been a glass shrine, by Josef Amberg, containing a thighbone of Adalbero as a relic.
