The primary governing body for professional football leagues globally is the Fédération Internationale de Football Association (FIFA). Founded in 1904, FIFA oversees international competitions such as the World Cup and establishes the rules of the game through the International Football Association Board (IFAB). This organization promotes the development of football worldwide, ensuring a consistent application of the laws, and coordinates various initiatives to expand the sport's reach. FIFA plays a critical role in fostering both amateur and professional football globally.
