Prussian Union of Churches

The Prussian Union of Churches was a Protestant church federation established in 1817 by the Kingdom of Prussia to unify Lutheran and Reformed (Calvinist) denominations under a single church administration. Its goal was to promote religious unity, but it often caused controversy among believers who valued their doctrinal traditions. The Union sought to integrate different Protestant groups, shaping church policies and practices across Prussia. Over time, it reflected state influence on religion, raising debates about church independence and religious diversity within Protestantism in Germany.
