The Great Medieval Battles system was a late 1970s SPI Quad wargame. The system contained both historical and fictional battles (King Arthur).
The system was revisited with Strategy & Tactics games :
- three battles were updated with new graphics and rule fixes (Great Medieval Battles Bannockburn and Angora & Navarette in Black Prince: Crecy & Navarette)
- one battle, not found in the original quad, was added (Crecy in Black Prince: Crecy & Navarette)
