The only method for women to compete was to enter horses in equestrian sports. There are some successful female horse owners on record. They were awarded with the victory despite the fact that they were most likely not present at the events. Women's events began as late as 1948 and 1952 although they were rarely held during the early years of the games. Until 1912, when modern pentathlon was introduced, the only way for a woman to compete was in a duel with a man. The winner was the person who scored more hits against her opponent - either by hitting him or by avoiding being hit herself. This is how women participated in the Olympic Games until 1948 when they were allowed to enter regular events too. Even though pentathlon is still used by some countries as a men's event, it can also be competed by women. In 1956, women were admitted into boxing for the first time. Since then, they have been regularly included in all Olympic boxing tournaments except for 1976 when they withdrew themselves after the bombing of Tiananmen Square. In 2000, they were again invited to participate but only eight nations sent athletes to box instead. Although the number of participants has dropped, women are still allowed to fight under the same rules as the men. From 1912 to 1948, women could only participate in equestrian events.
