[1] The Diet of Torda (1557) established three schools in the former monasteries of Kolozsvár (Cluj-Napoca), Marosvásárhely (Târgu Mureş) and Nagyvárad (Oradea).

Queen Isabella, regent for the infant John Sigismund, granted the school in Kolozsvár the annual sum of 100 forints.

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 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.

Prominent Hungarian-speaking Unitarian alumni of the 19th century included Sámuel Brassai, poets Mihály Szentiváni and János Kriza, historians Elek Jakab and László Kővári, chemist Áron Berde and the writer Domokos Gyallai.
