Soccer has resulted in many fight over the ages. In 19th century England
they had no rules so soccer fights often occurred. During these times is
when they started applying rules. Without strict rules, the officials,
referees, would often get into fights constantly with players and coaches.
The rules are called The Rules Of The Game. Because there are so
many, this page will only explain the seventeen main ones. The rules are
