The Battle of Parma was fought on 18 February 1248 between the forces of Holy Roman Emperor Frederick II and the Guelphs. The Guelphs attacked the Imperial camp when Frederick II was away. The Imperial forces were defeated and much of Frederick's treasure was lost.
The Battle of Parma was re-enacted on 18 February 1248 between the Guelphs and the forces of Holy Roman Emperor Frederick II.
February 18th, 1248 is when the battle was originally fought. It cannot have been re-enacted before this date. The system was fooled due to the lack of distinction between fighting a battle and re-enacting one.
