1904 Olympic Games in the context of "Washington University in St. Louis"

Catch wrestling (also known as catch-as-catch-can) is an English wrestling style with fewer restrictions than other wrestling styles. It allows techniques using or targeting the legs (unlike Greco-Roman wrestling), it allows joint locks (unlike freestyle wrestling and Greco-Roman wrestling), and there are no mandatory grips. It was spread by wrestlers of travelling funfairs who developed their own submission holds, referred to as "hooks" and "stretches", into their wrestling to increase their effectiveness against their opponents, as well as immigrants through Europe and the Anglosphere.

Catch-as-catch-can was included in the 1904 Olympic Games and continued through the 1936 Games; it had new rules and weight categories introduced similar to other amateur wrestling styles, and dangerous moves – including all submission holds – were banned. At the amateur level, FILA developed and codified new rules and regulations to replace catch wrestling with freestyle wrestling, which was then considered separate from the dangerous, professional catch style. After a revival effort starting in the 1980s, competitive catch wrestling gradually made a return, leading to The Snake Pit's Catch Wrestling World Championships and notable competitions such as the Snake Pit British Championships and ACWA US Open.
