Compulsory figures were an important part of figure skating for the rest of the 19th century until the 1930s and 1940s. The first European Championships in 1891 consisted of only compulsory figures. In 1896, the newly formed International Skating Union (ISU) sponsored the first annual World Figure Skating Championships in St. Petersburg. The competition consisted of compulsory figures and freeskating. Skaters had to perform six compulsory moves, or figures, so that judges could compare skaters according to an established standard. Compulsory figures were worth 60 percent of the competitors' total scores. Special figures were not included in World Championships, although they were included as a separate discipline in other competitions, including the Olympics in 1908.
