Ruch Chorzów (Polish pronunciation: [ˈrux ˈxɔʐuf]) is a Polish association football club based in Chorzów, Upper Silesia. It is one of the most successful football teams in Poland: fourteen-time national champions, and three-time winners of the Polish Cup. Currently the team plays in the top Polish league, the Ekstraklasa. Their stadium capacity is 10,000 seats. Ruch Chorzów has also had a very successful female handball team (9 times national champions).
The club was founded on 20 April 1920 in Hajduki Wielkie (then Bismarckhütte). It was known as Ruch Hajduki Wielkie until 1938, with Ruch (a common noun for motion) being sometimes interpreted by Polish patriots as a cover reference to the Silesian Uprisings. The club's first match, a 3:1 win against Orzeł Józefowiec, was played on 3 May 1920. In early 1939, the municipality of Hajduki Wielkie merged with Chorzów, which led to the club taking on its current name Ruch Chorzów. After the German occupation of Poland in 1939, the club was renamed Bismarckhütter SV 99 and joined the Gauliga Oberschlesien in 1941; however, it reverted to its old name in 1945. In 1948, under communist pressure (Stalinisation), the club was renamed Unia Chorzów, in 1955 it became Unia-Ruch, and finally in 1956 returned to the name Ruch. The current team sponsor is the Great Orchestra of Christmas Charity.
