Ex commisso nobis was a papal bull issued on July 7, 1136 by Pope Innocent II in Pisa. His election six years earlier prompted a schism in the Western Church. The Polish church supported the appointment of the Antipope Anacletus II, while St. Norbert, Archbishop of Magdeburg, remained faithful to Innocent. In August 1135, in exchange for the independence of the Polish bishops, Bolesław III Wrymouth, Duke of Poland, declared himself a vassal of Emperor Lothair and agreed to pay tribute to the Imperial Curia. On July 7, 1136, Pope Innocent upheld the independence of the Polish church from the German Archdiocese of Magdeburg via the Bishopric of Gniezno
