Under the rule of Emperor Charles VI, the Bishops of Alba Iulia were able to return to their restored domains, as the see was removed from Protestant rule (1713). The diocese was completely restored in 1771, under Empress Maria Theresia. The defunct provostship of Szeben was not revived, and its assets went instead to the main diocese. It was also under Maria Theresia that Catholic teaching and school administration came under the supervision of the "Commissio catholica" (this remained the rule under the Austrian Empire and the early years of Austria-Hungary).
