Professional wrestling is a form of athletic theater that combines mock combat with drama, under the premise that the performers are competitive wrestlers. Although it entails elements of sports wrestling and martial arts, including genuine displays of athleticism and physicality before a live audience, professional wrestling is distinguished by its scripted outcomes and emphasis on entertainment and showmanship. The staged nature of matches is an open secret, with both wrestlers and spectators nonetheless maintaining the pretense that performances are bona fide competitions; this is likened to the suspension of disbelief employed when engaging with fiction.

The history of professional wrestling in the United Kingdom spans over one hundred years beginning in the 1920s, when it was popularised under the concept of "All in Wrestling", which emphasised an "anything goes" style and presentation. Following World War II, the style and presentation of professional wrestling in the UK underwent a dramatic shift, as the Admiral-Lord Mountevans rules were introduced to make British professional wrestling appear much closer to a legitimate sport. Professional wrestling entered the mainstream British culture when the newly-formed independent television network ITV began broadcasting it in 1955, firstly on Saturday afternoons and then also in a late-night midweek slot. Domestically produced professional wrestling was at its peak of popularity when the television show World of Sport was launched in the mid-1960s, making household names out of Adrian Street, Mick McManus, Giant Haystacks, Jackie Pallo, Big Daddy, Mark Rocco, Steve Veidor, Dynamite Kid, and Kendo Nagasaki.
