Football encompasses a group of team sports that revolve around kicking a ball to score goals. The specific sport referred to as "football" depends on regional popularity. Various forms of football, including association football (soccer), Australian rules football, Gaelic football, gridiron football (American football), International rules football, rugby league, and rugby union, share common ancestral roots and are recognized as distinct "football codes." These codes exhibit varying degrees of similarity in their rules and gameplay.
