1517: On the eve of All Saint's Day, Martin Luther posts his 95 theses on the door of the Castle Church in Wittenberg, Germany, arguing that Christians were being falsely told that they could find absolution from sin through the purchase of "indulgences" from the Catholic Church. Luther's actions would spark the Protestant Reformation.
