Catch wrestling is a classical hybrid grappling style and combat sport. It was developed by J. G. Chambers in Britain circa 1870. It was popularized by wrestlers of travelling funfairs who developed their own submission holds, or "hooks", into their wrestling to increase their effectiveness against their opponents. Catch wrestling derives from various different styles: several English styles of wrestling (Cumberland, Westmorland, Cornwall, Devon, and Lancashire), Indian pehlwani, and Irish collar-and-elbow wrestling. The training of some modern submission wrestlers, professional wrestlers and mixed martial artists is founded in catch wrestling.
