Following the Battle of Mohács in 1526 the kingdom of Hungary was divided into three parts: the north and west came under Habsburg rule, the east formed the new principality of Transylvania while the rest was occupied by the Ottomans. That division created a favourable environment for the spread of the Reformation. The new religious ideas had already spread quickly to Hungary after 1517 with merchants and students from the German-speaking communities of the royal free cities being among the first to adopt and disseminate them. Even the royal couple, King Louis II and Queen Mary of Habsburg, showed a receptiveness to the Reformation through their relationship with Prince George of Brandenburg. However, after Mohács 75 per cent of Hungary’s medieval parishes collapsed and different variants of Protestantism won wide support across all three areas into which the former kingdom was divided. Antitrinitarianism also gained many adherents in those parts of Hungary that were not subject to the Habsburgs. Between the Catholics, Protestants and Antitrinitarians, as well as the substantial Orthodox Christian communities in the region, and the Muslims in Ottoman areas, Hungary became remarkably multi-confessional. However, the Catholic Church retained enough support across all three areas to form the basis of a remarkable renewal under Habsburg auspices in the seventeenth century.
