International sports competition where competitors represent their nation
A world cup is a global sporting competition in which the participant entities – usually international teams or individuals representing their countries – compete for the title of world champion. The event most associated with the name is the FIFA World Cup for association football, which dates back to 1930. Since then there have been a number of sporting events labeled "world cup", such as the ICC Men's Cricket World Cup, the Rugby World Cup, Rugby League World Cup, and the Hockey World Cup.
