Waterpolo is a team sport played in a pool where teams score goals. It originated in Scotland in the late 19th century and was developed by William Wilson. The world's best team is the Hungarian National Men's Water Polo Team, which has won 9 Olympics and 3 World Championships. One famous match was the 1956 Summer Olympics semifinal between Hungary and the Soviet Union, where Hungary defeated the Soviets 4-0 during the Hungarian Revolution. Dénes Kemény and Tibor Benedek have both been head coaches of Hungary's men's national water polo team.
