Martin Luther, (born Nov. 10, 1483, Eisleben, Saxony—died Feb. 18, 1546, Eisleben), German priest who sparked the Reformation.
Luther studied philosophy and law before entering an Augustinian monastery in 1505. He was ordained two years later and continued his theological studies at the University of Wittenberg, where he became a professor of biblical studies.
On a trip to Rome in 1510 he was shocked by the corruption of the clergy and was later troubled by doubts centring on fear of divine retributive justice. His spiritual crisis was resolved when he hit on the idea of justification by faith, the doctrine that salvation is granted as a gift through God’s grace.
Luther urged reform of the Roman Catholic Church, protesting the sale of indulgences and other abuses, and in 1517 he distributed to the archbishop of Mainz and several friends his Ninety-five Theses (according to legend, Luther nailed the theses to the door of the castle church in Wittenberg); the theses questioned Roman Catholic teaching and called for reform. In 1521 he was excommunicated by Pope Leo X and declared an outlaw at the Diet of Worms.
Under the protection of the elector of Saxony, Luther took refuge in Wartburg. There he translated the Bible into German; his translation has long been regarded as the greatest landmark in the history of the German language.
He later returned to Wittenberg, and in 1525 he married the former nun Katherine of Bora, with whom he raised five children.
Though his preaching was the principal spark that set off the Peasants’ War (1524–25), Luther’s vehement denunciation of the peasants contributed to their defeat.
Luther’s break with Rome led to the founding of the Lutheran Church; the Lutheran confession of faith or, Augsburg Confession, was produced with Luther’s sanction by Philipp Melanchthon in 1530.
Luther’s writings included hymns, a liturgy, and many theological works.
