Suppression of the Society of Jesus
Emmerich Joseph von Breidbach zu Bürresheim introduced several reforms during his time as Archbishop of Mainz. The number of holidays was reduced. Schools and monasteries in the archbishopric were modernized to reflect the latest in Enlightenment thinking. Education was removed from the care of the church, and an independent teacher's academy opened on May 1, 1771. In 1773, Pope Clement XIV issued the papal brief "Dominus ac Redemptor", resulting in the Suppression of the Society of Jesus and as a result, the Society of Jesus, which had run Mainz's system of higher education, was expelled from the Archbishopric of Mainz.
