The Czechoslovak First League was the premier football league in the Czechoslovakia from 1925 to 1993, with the exception of World War II. Czechoslovakia was occupied by German forces who formed Gauliga Sudetenland and Gauliga Böhmen und Mähren leagues on occupied territories. Until 1934-35 season no teams from Slovakia participated in the league. Czechs were allowed to run their own league in the Protectorate of Bohemia and Moravia, while Slovaks were granted their own independent Slovak State and created their own league. After the World War II the league was recreated.
