Different forms of football have existed for centuries. Game playing, particularly football, was encouraged at Rugby School by influential headmaster Thomas Arnold (1828–42), and many boys educated at this time were instrumental in the expansion of the game. Rugby football soon became one of the most significant sports in the promotion of English and, later, British imperial manliness. The cult of manliness that resulted centred on the public schools and the Universities of Oxford and Cambridge, where boys were sent to learn how to become young gentlemen. By this time, hacking had largely disappeared from club rugby, though it remained a part of the game's "character building" qualities at Rugby School.
