Although the first reference to cricket appeared in the 13th century, the game only gained popularity in the 17th century, when English aristocrats started playing it. They decreed that cricket would be played in 'a gentlemanly manner' , which means no sledging, cheating, bodyline bowling , temper tantrums or excessive appealing. If the batsman knew he was out, he should 'walk' even if the umpire decided otherwise.
