Claude Vaussin used
canonical visitations as a means of monitoring monastic life in Cistercian abbeys. He made two large trips through French monasteries as a visitor in 1648 and 1653. 1654 saw him visiting Swiss, German, Bohemian and Austrian abbeys. The "National Chapter" at
Rottweil in 1654, during which Vaussin himself presided at, improved the unity of the
Upper German Congregation within its own ranks and strengthen its ties to its mother abbey of Cîteaux. The German abbots became Vaussin's strongest allies in his conflicted relations to the French abbots of the Strict Observance. The following abbatial elections in the primary abbeys of
Clairvaux (1653) and
La Ferté (1655) resulted in abbots who Vaussin had endorsed. But after 1656, the Strict Observance rose to new dominance. The French court continued their support, and in 1660, La Rochefoucauld declared the Reformed statutes to be binding. Vaussin canceled the General Chapter which had been called for 1661 and protested against the court's actions to the Vatican, traveling there personally in order to attain its retraction. Pope
Alexander VII. (1655–1667) called a meeting of representatives of both observances to be held at Rome on 26 January 1662, (Feast of St.
Alberic, Abbot of Cîteaux): Vaussin represented the Order, and the abbots Dominique Georges (Le Val-Richer Abbey) and
Jean de Rancé (
La Trappe Abbey) represented the Strict Observance. The result was the founding of a special commission to examine the dispute between the camps. Several years later, the special commission produced the
Apostolic Constitution of 19 April 1666 titled
In suprema. It was accepted by all parties, including the Strict Observance. A General Chapter was held in 1667 and officially distributed and endorsed the text. The General Abbot died after 24 years of service as the head of the Order, aged 63, in Dijon. == Legacy ==
