Ninety-five Theses

Disputation by Martin Luther on indulgences

The Ninety-five Theses or Disputation on the Power and Efficacy of Indulgences is a list of propositions for an academic disputation written in 1517 by Martin Luther, then a professor of moral theology at the University of Wittenberg, Germany. The Theses is retrospectively considered to have launched the Protestant Reformation and the birth of Protestantism, despite various proto-Protestant groups having existed previously. It detailed Luther's opposition to what he saw as the Roman Catholic Church's abuse and corruption by Catholic clergy, who were selling plenary indulgences, which were certificates supposed to reduce the temporal punishment in purgatory for sins committed by the purchasers or their loved ones.
