Football
Events
 * The traditional date of the William Webb Ellis legend. He is the Rugby School pupil who, it is said, "with a fine disregard for the rules of football, took the ball in his hands and ran with it".  Even if the tale is true, the game will have been a version of folk football with rules that had been verbally agreed by the Rugby School pupils.  Such rules are always open to challenge and it may be that an incident like this did occur with the result that a "dribbling" game became primarily a handling game.
