On Sunday, 26 September 1937 in Częstochowa, a conference of regional teams from across the nation took place, to discuss the creation of the league.
Officials of several clubs arrived, such as Brygada Częstochowa, Gryf Toruń, Śmigły Wilno, Rewera Stanisławów, Dąb Katowice, Unia Sosnowiec, Strzelec Janowa Dolina, and WKS Grodno.
Also, invited were officials of HCP Poznań, Podgorze Kraków, Naprzód Lipiny and Union Touring Łódź, but for unknown reasons they did not show up.
In the year of the 1921 Polish Football Championship only five A-Classes managed to conclude the full seasons, namely: Poznań, Lwów, Kraków, Warsaw and Łódź.
Football system in some areas located mainly in the Eastern Provinces (Kresy Wschodnie) was not developed enough (or did not have enough teams) to keep their own A-Class Leagues.
Śląsk, with such renowned players as Hubert Gad and Ewald Cebula, at home beat both Fablok and Unia 4-0.
