Declared an outlaw by Emperor Charles V at the Diet of Worms (April 1521), Luther was "kidnapped" by friendly forces and hidden at Wartburg Castle (May 1521–March 1522). There, he translated the New Testament into German—democratizing scripture.
Despite the imperial ban, Luther returned to Wittenberg under the protection of Elector Frederick the Wise. He restored order amid radical reforms (Karlstadt), preaching against iconoclasm and for structured change.
Luther's rhetoric inspired uprisings. His pamphlet Against the Murderous, Thieving Hordes of Peasants urged nobles to crush the revolt—alienating many commoners but securing princely support.
Luther remained in Wittenberg, teaching, writing, and organizing the territorial church until his death in 1546. The Edict of Worms was never enforced against him due to political fragmentation in the Empire.
