Rugby league in the British Isles
Rugby league is played across England, Ireland, Scotland and Wales, but its heartland in parts of Northern England is where the sport is most popular, and is where the majority of professional clubs are based. The sport was first established in the George Hotel, Huddersfield, where 22 clubs split from the Rugby Football Union to form the Northern Rugby Football Union.
