 By the end of the 19th century, this modern "Greco-Roman" wrestling style went on to become the most fashionable sport in Europe, and in 1898 the Frenchman Paul Pons, “the Colossus” became the first Professional World Champion.The modern style of professional wrestling, popularized by the United States and United Kingdom during the late 19th century, is called the catch-as-catch can style.Originally thought of as unorthodox and more lax in style, catch wrestling differs from Greco-Roman in its allowed grapples; Greco-Roman strictly prohibits grabbing below the waist, while catch wrestling allows holds above and below the waist, including leg grips.
