In 1517, the Dominican friar Johann Tetzel preached for the sale of indulgences in the German dioceses of Magdeburg and Halberstadt. Additionally, he preached at JĆ¼terbog, a town located near Wittenberg, during the spring of that year.1
These activities, authorized by Pope Leo X to help fund the rebuilding of St. Peterās Basilica, were widely viewed as an abuse of the sacrament of penance and served as the catalyst for Martin Luther to draft his Ninety-five Theses, ultimately sparking the Reformation.1
