For much of rugby's history, a mark could be made anywhere on the field, but under more stringent conditions: the marking player had to have both feet on the ground at the time of calling "Mark!", the defending side were allowed to advance as far as the mark in defending against the subsequent kick, and the kick itself had to propel the ball at least as far forward as the mark (in conjunction with the second stipulation, this effectively prevented the marking side from keeping possession with a tap-kick). However, under these restrictions a
goal could be attempted. In the 1970s the mark was changed to the definition given above, except that it could be made anywhere in the defending side's 22; it is no longer a requirement that the marking player have both feet on the ground. ==Other football codes==
