From the late 19th century, Wales became famous as the "land of song", and for its Eisteddfod culture festival. At many international sport events, for example the FIFA World Cup, the Rugby World Cup, and the Commonwealth Games, Wales competes on its own, as a separate country. However, at most international events, such at the Olympics, Wales competes with the rest of the Great Britain, and sometimes as the United Kingdom with Northern Ireland included. Rugby Union is strongly associated with Wales as a national sport.
