On 31 October 1517 the Augustinian friar and theology professor Martin Luther circulated his Ninety-five Theses at Wittenberg, attacking the sale of indulgences and questioning papal authority over salvation.
Intended as an academic disputation, the theses were rapidly translated, printed and distributed across the Holy Roman Empire, igniting a wider movement of religious protest. Luther's central conviction, that salvation came through faith and divine grace rather than works or Church-mediated merit, and his appeal to scripture alone as the ultimate authority, challenged the doctrinal and financial foundations of the medieval Church. The controversy escalated into the Protestant Reformation, fracturing Western Christendom into competing confessions, fuelling more than a century of religious war, and reshaping European politics, the relationship between church and state, and patterns of literacy and vernacular culture. The Reformation stands among the defining turning points of European and world history.
