This chapter aims to define the limits of religious toleration of the Eastern Orthodox Church in those areas of Europe which remained outside of direct Ottoman or Muscovite rule in the early modern period. The rudimentary confessional balance that had obtained between the Eastern and the Latin Churches in the kingdom of Poland, the Grand Duchy of Lithuania, the Transylvanian principality and the kingdom of Hungary was disturbed by the arrival of Protestantism in the second quarter of the sixteenth century. The growing numerical strength and political influence of Evangelical nobles and burgesses necessitated the introduction of toleration as a state policy. When it was set in place, however, the politically emasculated believers of the Eastern Church were either effectively excluded from, or found themselves on the bottom rung of a tiered system of, official toleration. The survival of Orthodox privilege in Moldavia and Wallachia, and the full religious toleration granted by the Habsburgs to the South Slav peoples in exchange for their support in defending the imperial frontiers from the Ottomans, underscore the significance of political authority and instruments of violence in the hands of local élites for the preservation of traditional Orthodox identity.
