Martin Luther was born on November 10, 1483, in Eisleben, Germany.¹⁾

He was a German professor of theology, composer, priest, and key figure in the Protestant Reformation.²⁾

Luther's religious beliefs were shaped by his experience during a thunderstorm when he vowed to become a monk if he survived, which led him to join an Augustinian monastery.³⁾

Luther's most famous work, “Ninety-Five Theses,” was a list of arguments against the Catholic Church's practice of selling indulgences. He posted it on the door of the Wittenberg Castle Church on October 31, 1517.⁴⁾

His act of posting the Ninety-Five Theses is often considered the starting point of the Protestant Reformation.⁵⁾

Luther's ideas challenged the authority of the Pope and the Catholic Church, sparking a theological debate that led to significant religious and social changes in Europe.⁶⁾

He translated the Bible into German, making it accessible to the common people and contributing to the development of the German language.⁷⁾

Luther's translation of the Bible played a crucial role in the spread of the Reformation, as it allowed people to read and understand the scriptures without relying on Latin translations.⁸⁾

He believed in “sola scriptura,” the idea that the Bible alone is the ultimate authority in matters of faith and doctrine.⁹⁾

Luther's teachings emphasized salvation through faith alone, “sola fide,” rather than through good works or indulgences.¹⁰⁾

He married Katharina von Bora, a former nun, breaking away from the celibate tradition of the Catholic Church.¹¹⁾

Luther and Katharina had six children and provided a model of marriage for Protestant clergy.¹²⁾

Luther was known for his strong and sometimes controversial rhetoric, including his harsh criticism of the Pope and the Catholic Church.¹³⁾

He wrote numerous hymns, including the famous “A Mighty Fortress Is Our God,” which became a staple in Protestant worship.¹⁴⁾

Luther's writings greatly influenced the development of modern standard German, as he used the language to communicate his ideas to the wider public.¹⁵⁾

He faced excommunication by Pope Leo X in 1521, following his refusal to recant his views at the Diet of Worms.¹⁶⁾

Luther was declared an outlaw by the Holy Roman Emperor Charles V, making it dangerous for him to travel without protection.¹⁷⁾

During his time in hiding at Wartburg Castle, Luther translated the New Testament into German in just eleven weeks.¹⁸⁾

His translation of the New Testament was published in September 1522, marking a significant milestone in the spread of the Reformation.¹⁹⁾

Luther's teachings had a profound impact on the political landscape of Europe, leading to the formation of various Protestant denominations and changing the balance of power between church and state.²⁰⁾
