The Counter-Reformation itself had an impact, with members of the Jesuit religious order being called into the region as early as 1579 (under the rule of Stefan Batory). In 1581, they founded an educational university in Cluj ("Kolozsvár"), nucleus of the present-day Babeş-Bolyai University. Originally protected by the powerful Báthorys, they continued to have a precarious status in Transylvania. Expelled in 1588-1595 (when Calvinism became official), and again in 1610-1615 (following the pressures of Gabriel Báthori), they continued their activities in the Moldavian region around Cotnari.
