The game of Cricket has been governed by The Rules of Cricket for over 250 years. These Rules of Cricket have been subject to additions and alterations recommended by the governing authorities of the time. Since its formation in 1787, the Marylebone Cricket Club (MCC) has been recognised as the sole authority for drawing up the Rules of Cricket and for all subsequent amendments.

The Rules of Cricket have stood up remarkably well for over 250 years of playing the game. It is thought the real reason for this is that cricketers have traditionally been prepared to play in the Spirit of the Game as well as in accordance with the Laws.

In 2000, the MCC has revised and re-written the Rules of Cricket for the new Millennium. In this Code, the major innovation is the introduction of the Spirit of Cricket as a Preamble to the Laws. Whereas in the past it was assumed that the implicit Spirit of the Game was understood and accepted by all those involved, now MCC feels it right to put into words some clear guidelines, which will help to maintain the unique character and enjoyment of the game. The other aims have been to dispense with the Notes, to incorporate all the points into the Rules of Cricket and to remove, where possible, any ambiguities, so that captains, players and umpires can continue to enjoy the game at whatever level they may be playing.
