Martin Luther

Martin Luther (November 10, 1483 – February 18, 1546) was a German friar, theologian, and author whose work inspired the Protestant Reformation, fundamentally transforming Christianity and European society. Born in Eisleben, Saxony, Luther studied law before joining an Augustinian monastery and pursuing theology. In 1517, he famously posted his 95 Theses criticizing the Catholic Church's practice of selling indulgences, sparking theological debate that cascaded across Europe. Excommunicated in 1521, Luther continued his work translating the Bible into vernacular German, making Scripture accessible to common people rather than only clergy and scholars. He established the theological foundations of Protestantism, emphasizing faith alone (sola fide) and the authority of Scripture above Church tradition. Luther's writings and ideas spread rapidly through the newly invented printing press, reaching millions and influencing rulers across Europe. His translation work significantly shaped the development of the German language itself. Though Luther held controversial views on some topics, his challenge to institutional Church authority and emphasis on individual conscience reading Scripture directly transformed Western Christianity and contributed to the development of modern concepts of religious freedom and individualism.
