Martin Luther was a German monk who forever changed Christianity when he nailed his '95 Theses' to a church door in 1517, sparking the Protestant Reformation. Luther was born on November 10, 1483, in Eisleben, Saxony, located in modern-day Germany. At 14, Luther went north to Magdeburg, where he continued his studies. In 1498, he returned to Eisleben and enrolled in a school, studying grammar, rhetoric, and logic. He later compared this experience to purgatory and hell. On October 31, 1517, Luther, angry with Pope new round of indulgences to help build St. Peter’s Basilica, nailed a sheet of paper with his 95 Theses on the University of Wittenberg’s chapel door. Luther died following a stroke on February 18, 1546, at the age of 62 during a trip to his hometown of Eisleben. He was buried in All Saints' Church in Wittenberg, the city he had helped turn into an intellectual center. Luther's teachings and translations radically changed Christian theology. Thanks in large part to the Gutenberg press, his influence continued to grow after his death, as his message spread across Europe and around the world.
