Summary

Martin Luther was a subject of the Elector of Saxony in the Holy Roman Empire. His emergence as a reformer was made possible by the sponsorship he received in Wittenberg. He owed his survival to the protection afforded him by the Elector when Emperor Charles V outlawed him and ordered that the papal ban of excommunication be enforced in the empire. The audience to which Luther appealed was the general population of German Christians, both lay and ecclesiastical, who wanted a reform of the church and the reduction of the pope’s influence over it. That his appeal resonated so widely and so profoundly had much to do with a combination of crises that had developed in the empire from the 15th century. That his reform proposals resulted in the formation of a new church owed everything to the political structures of the empire. These facilitated the suppression of radical challenges to Luther’s position. They also thwarted every effort Charles V made over several decades to ensure that the empire remained Catholic. Lutheranism became entwined with the idea of German liberty; as a result, its survival was secured in the constitution of the empire, first in 1555 and then in 1648.
