Shin-kicking, also known as hacking or purring, is a combat sport that involves two contestants attempting to kick each other on the shin to force their opponent to
the ground. It has been described as an English martial art.
It originated in England in the early 17th century, and was one of the most popular events at the Cotswold Olimpick Games until the games ended in the 1850s. It also became a popular
pastime among Cornish miners. In the 19th century the sport was also practised by British immigrants to the United States. It was included in the 1951 revival of the Cotswold Olimpick
Games, and remains one of its most popular events, run as the World Shin-kicking Championships.
