From Wikipedia
Medieval football is a modern term used for a wide variety of the localised informal football games that were invented and played in Europe during the Middle Ages. Alternative names include folk football, mob football and Shrovetide football. These games may be regarded as the ancestors of modern codes of football, and by comparison with later forms of football, the medieval matches were chaotic and had few rules.
