CORSIER-SUR-VEVEY, Switzerland (May 23) -- The World Wrestling Day is celebrated on May 23 every year. It marks the occasion of first-ever unofficial World Championships held in Vienna, Austria in 1904. Since then, wrestling day has been a celebration for the wrestling family around the world.

The 1904 World Championships was held only in two weight classes of Greco-Roman and five countries participated in the tournament. There were 26 wrestlers -- 19 from Austria, three from Denmark, two from Germany and one each from Hungary and Bohemia, a former kingdom in Europe.

United World Wrestling wishes everyone a happy World Wrestling Day.
