On October 31, 1517, Martin Luther, a German monk and theologian, famously posted his Ninety-Five Theses on the door of the Castle Church in Wittenberg, challenging the practices of the Catholic Church, particularly the sale of indulgences.

Luther's actions were centered around the Castle Church in Wittenberg, a key location for the Protestant Reformation. The theses sparked widespread debate and were quickly spread across Europe thanks to the printing press.

The publication of the Ninety-Five Theses led to the Protestant Reformation, which significantly changed the religious landscape of Europe and prompted the establishment of various Protestant denominations. Many saw Luther's work as a call for reform rather than a split from the Church.

Initially, Luther faced opposition from church authorities, but public sentiment gradually shifted in his favor, as many believed reform was necessary. This event ignited discussions about faith and salvation that continue in various forms to this day.

Luther's Theses, originally intended for academic discourse, quickly went viral—thanks to the printing press—and found their way into the hands of everyday people, marking a significant moment in history where ideas began to circulate freely.
