Today in the Middle Ages: October 15, 1518

On October 15, 1518, Martin Luther was summoned before a Papal legate in Augsburg, Germany, but refused to recant his 95 Theses.

Luther saw himself as a reformer, not an iconoclast. He was particularly opposed to the selling of indulgences, a practice which had been widely condemned for centuries, even as it continued to the benefit of churchmen. However, by following his principles and entering into debate with the Church, he contributed greatly to the development of Protestantism in Europe.
