In Olympic competition, countries of the former Soviet Union, Bulgaria, Turkey, South Korea, Romania, Japan, Sweden, and Finland have had great success. Carl Westergren of Sweden won three Greco-Roman gold medals in 1920, 1924, and 1932, and was the first Greco-Roman wrestler to do so. Alexander Karelin did the same in 1988, 1992, and 1996. Ivar Johansson of Sweden won gold medals in Greco-Roman in 1932 and 1936 and also a gold medal in freestyle in 1932. The United States Olympic delegation (exclusively wrestling freestyle before) first entered Greco-Roman wrestling in 1952 and has taken three gold medals, won by Steve Fraser and Jeffrey Blatnick in the 1984 Los Angeles Olympic Games, and by Rulon Gardner at the 2000 Olympic Games in Sydney, Australia.
