 According to the treaty, RudolphII recognized Sigismund's hereditary right to rule Transylvania and Partium and to use the title of prince, but he also stipulated that the principality was to be re-united with the Hungarian Crown if Sigismund's family died out.The Diet of Transylvania confirmed the treaty on 16April.The Diet also prohibited religious innovations, which gave rise to the persecution of Szekler Sabbatarians in Udvarhelyszék.
