Men's swimming became part of the first modern Olympic Games in 1896 in Athens. In 1902, the Australian Richmond Cavill introduced the front crawl to the Western world. In 1908, the world swimming association, Fédération Internationale de Natation (FINA), was formed. Women's swimming was introduced into the Olympics in 1912. Butterfly was developed in the 1930s and was at first a variant of breaststroke, until it was accepted as a separate style in 1952.
