The FIFA World Cup, sometimes called the Football World Cup or the Soccer World Cup, but usually referred to simply as the World Cup, is an international football competition contested by the men's national football teams of the member nations of Fédération Internationale de Football Association (FIFA), the sport's global governing body. The championship has been awarded every four years since the first tournament in 1930, except in 1942 and 1946, due to World War II.
