When Transylvania fell under Habsburg rule the
Diploma Leopoldinum (1690) granted the rights of all four received Christian denominations (
religio recepta):
Catholic,
Augustan (
Lutheran),
Helvetic (
Reformed Church in Hungary) and
Unitarian and a process of re-Catholicisation followed. The building which had been used 1557–1693 for the Unitarian High School was returned to the Jesuits. The school moved to four buildings on the Town Square, nearby St. Michael’s Church which remained in Unitarian hands. However on 6 May 1697 most of Cluj-Napoca was destroyed in major fire - including the School. The school's rector was sent to the Netherlands to raise funds from Unitarian and
Arminian supporters. Following the defeat of
Francis II Rákóczi, the Catholic church finally regained possession of St. Michael’s Church, and in 1718 the recently rebuilt school buildings on the square. The school relocated to what is today 21 December St.
Andrzej Wiszowaty Jr., great-great grandson of
Fausto Sozzini, taught at the college 1726-1740, during the period in the 1730s when the Unitarian Church was reorganized and strengthened by
Mihály Lombard de Szentábrahám. ==19th century==
