The Massacre of Vassy, also known as the Massacre of Wassy, is the name given to the murder of Huguenot worshipers and citizens in an armed action by troops of Francis, Duke of Guise, in Wassy, France on 1 March 1562. The tragedy is identified as the first major event in the French Wars of Religion. The series of battles that followed concluded in the signing of the Edict of Amboise the next year, on 19 March 1563. The events surrounding the Massacre of Wassy became widely known by a series of forty engravings published in Geneva seven years later.
