c.1140 - c.1217
Peter Waldes (or Valdes) was the founder of a religious movement that originated in France (the Waldenses) to follow Christ in poverty and simplicity.
Pope Lucius III placed the Waldenses under ban with his bull 'Ad abolendam' but Peter Waldes and his 'Paupers' (The Poor) continued to preach. The movement spread to Spain, Germany and southern Italy but by the end of the 13th century persecution had virtually eliminated the sect in many areas.
