The first recognized sport official in football is often considered to be the referee, a role established in the late 19th century as the sport began to formalize its rules. The first known reference to a football referee dates back to 1863, when the Football Association (FA) was formed in England. The referee's role was to ensure that the rules of the game were followed and to maintain order during matches. This position has since evolved into a critical aspect of the game, with officials now undergoing extensive training and certification.
Usually there are four officials, a referee, two linesmen and a fourth referee to show the time or change in player, or if the referee can not take further part.
