king was once again reinforced. Adalbero and other princes therefore in March 1077 appointed as anti-king Duke Rudolf of Rheinfelden. Henry IV, hastened to return to Germany, and in the same year besieged Wurzburg. Wurzburg was strategically important because it controlled communications between the rebel areas of Saxony and Swabia. Having succeeded in raising the citizens against Adalbero, the bishop had to leave the city. King Henry appointed a series of anti-bishops. In 1086 Rudolf of Rheinfelden returned him to Würzburg, but he was soon ejected again. Adalbero rejected all attempts at mediation, saying that he would die rather than yield. At the Synod of Mainz in 1085 therefore he was formally deposed and forced into exile. He remained faithful to the pope, and was sent to his monastery in Lambach. In 1088 Adalberone renounced his episcopal dignity and dedicated the monastery of Komburg, near Schwabisch Hall, in Württemberg. The following year, he was also co-founder of Zwiefalten Abbey in Swabia. On 6 October 1090 he died in Lambach and was buried in the abbey church which he himself had founded and dedicated. Veneration Soon after his death he began to be venerated as a saint in his Austrian home, and his veneration in Münsterschwarzach is evidenced since the 17th century. In 1883 Pope Leo confirmed Adalbero a saint in the worldwide church. In the "Neumünsterkirche" in Würzburg since 1948 there has been a glass shrine, by Josef Amberg, containing a thighbone of Adalbero as a relic. Also in Würzburg is the neo-Romanesque St. Adalbero's church. Iconography Adalberone is represented with a church in his hand.
