FC Slovan Liberec (), commonly referred to as Slovan Liberec or simply Slovan, is a Czech football club based in the city of Liberec. The club is one of the most successful in the Czech Republic, having won three league titles and the domestic cup since 1993. Glass-making company Preciosa a.s. is the current main sponsor of the club. History The Early Years The first predecessor of the Liberec football club was the Reichenberger Fussballklub (RFK) which was founded in 1899 (renamed to Reichenberger Sportklub [RSK] in 1904). Because Liberec was a city where the majority of inhabitants were of German nationality, until 1945, it was Germans who first established clubs and played their own league.

In 1938, the Munich Agreement was signed, in which representatives of the United Kingdom, France, Italy and Germany forced Czechoslovakia to withdraw from their border area and surrender it to Germany. After the city of Liberec was incorporated into the Third Reich, Czech football in the city came to a halt for a full seven years. Post-War Era At the end of World War II and with the liberation of Czechoslovakia in 1945, Liberec took on the character of a Czech city. The first post-war game was played in Turnov on 10 June 1945 by Liberec's football club Slavia. On 15 July 1945, representatives of Czech football clubs from the border areas that had started up again met at the Radnice hotel. The result of the meeting was the verdict that each border-area club continue in the same league that it had played in up until 1938. After seven
