In 1445 John of Hagen obtained permission from the Council of Basel to restore the Divine Office to the original form of the old Benedictine breviary and to introduce liturgical and disciplinary uniformity in the monasteries that followed the reform of Bursfelde. A year later, on 11 March 1446, Louis d'Allemand, as Cardinal Legate authorized by the Council of Basel, approved the Bursfelde Congregation, which then consisted of six abbeys: Bursfelde, Clus, Reinhausen, Cismar in Schleswig-Holstein, St. Jacob's Abbey near Mainz, and Huysburg near Magdeburg. The cardinal likewise decreed that the Abbot of Bursfelde should always ex officio be one of the three presidents of the congregation, and that he should have power to convoke annual chapters. The first annual chapter of the Bursfelde Congregation convened in the Abbey of Sts. Peter and Paul at Erfurt in 1446.
