Cornwall has its own unique form of wrestling related to Breton wrestling. This has encouraged tournaments between the two nations. Cornish wrestling (also known as Wrasslin') is a regional, folk style of grappling or martial arts. The Cornish Wrestling Association was formed in 1923, to standardise the rules of the sport and to promote Cornish wrestling throughout Cornwall and the world. Together with Cornish hurling (a localised form of medieval football), Wrasslin' has been promoted as a distinctly Celtic game, tied closely with Cornish identity.
