Irish Travellers have a long history of bare-knuckle boxing. Toughness and the ability to fight are viewed as particularly important among Traveller men, and their involvement in boxing has extended to traditional amateur and professional boxing. Irish Traveller Francie Barrett represented Ireland at the 1996 Olympics, while Andy Lee fought for Ireland at the 2004 Olympics and later became the first Traveller to win a professional boxing world championship when he won the WBO middleweight title in 2014. Tyson Fury is of Irish Traveller heritage and defeated long-reigning Wladimir Klitschko in 2015 to become the unified heavyweight world champion.
