Artistic gymnastics
In 1881, the FIG was founded, and it remains the governing body of international gymnastics. It initially included only three countries and was called the European Gymnastics Federation until 1921, when the first non-European countries joined the federation and it was reorganized into its present form. Gymnastics was included in the program of the 1896 Summer Olympics, but women have been allowed to participate in the Olympics only since 1928. The World Championships, held since 1903, were open only to men until 1934. Since that time, two branches of artistic gymnastics have developed: women's artistic gymnastics (WAG) and men's artistic gymnastics (MAG). Unlike men's and women's branches of many other sports, WAG and MAG differ significantly in apparatus used at major competitions and in techniques.
Swimming (sport)
Men's swimming became part of the first modern Olympic Games in 1896 in Athens. In 1902, the Australian Richmond Cavill introduced freestyle 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; the first international swim meet for women outside the Olympics was the 1922 Women's Olympiad. Butterfly was developed in the 1930s and was at first a variant of breaststroke, until it was accepted as a separate style in 1952.
