In the Second Polish Republic, there was not a national, Second Division, as we know it today, although the creation of the second division was proposed on several occasions. On Sunday, September 26, 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. The officials talked about creation of a National B-League, but nothing came out of this project. Instead, in the years 1921-1939, several Voivodeships held their own games and those leagues were known as A-Classes. In 1927, the elite Polish Football League was created, which by the late 1930s consisted of 10 teams. The teams that did not make it to the Ekstraklasa, played in the A-Classes.

In the year of the 1921 Polish Football Championship only fire A-Classes managed to conclude the full seasons, namely: Poznań, Lwów, Kraków, Warsaw and Łódź. The next year they were joined by Wilno, Lublin (Volhynia) and Silesia.
Between 1927 and 1939 there were several A-Classes, such as:Kielce A-Class, from which in mid-1930s the separate, Zagłębie Dąbrowskie A-Class emerged, with teams from such cities as Sosnowiec, Będzin, Zawiercie or Częstochowa. After this, Kielce A-Class ceased to exist, and some of its teams, such as Star Starachowice, moved to Warsaw A-Class,
Białystok - Grodno A-Class,
Kraków A-Class, also called Kraków League,
Lwów A-Class, also called Lwów League,
Silesian A-Class, also called Silesia League (it was regarded as the strongest of all, with several top-quality teams and players),
Zagłębie Dąbrowskie A-Class (since mid-1930s).
It must be mentioned that not all Voivodeships had their own A-Classes. 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. So, there was no Nowogródek Voivodeship A-Class, or Tarnopol Voivodeship A-Class. Instead, the existing teams from those regions played each other in knock-out stage games, thus establishing a regional Champion.
Interesting is the fact that in several cases, teams from one Voivodeship played in the A-Class of another region - e.g. Koszarawa Żywiec from Kraków Voivodeship, played in mid-1930s in the Silesian A-Class, SKS (Star) Starachowice, played in late-1930s in Warsaw A-Class, even though the city of Starachowice was located in Kielce Voivodeship, or Pogon Stryj, which played in Lwów A-Class, but the town of Stryj was located in the Stanisławów Voivodeship.
Also, there were third and fourth tier Leagues in Poland - B-Classes (usually covering the areas of 4-5 counties) and C-Classes. Champions of these divisions were automatically promoted to upper levels.
To get promoted to the elite, 10-team Ekstraklasa, it was not enough to win the A-Class games. The promotion was a long and arduous process, which can be best described by recollecting the games of Śląsk Świętochłowice, which was the winner of the 1938-1939 Silesian A-Class. In the early summer 1939, Śląsk started its way to the Ekstraklasa. In the first stage, it competed against champions of the neighboring A-Classes - Fablok Chrzanów (Kraków A-Class) and Unia Sosnowiec (Zagłębie Dąbrowskie A-Class). Śląsk, with such renowned players as Hubert Gad and Ewald Cebula, at home beat both Fablok and Unia 4-0. Away, it tied 1-1 with Fablok and won 3-2 with Unia, becoming the Champion of southwest Poland A-Classes. In August 1939, the second, national stage started. In it, Śląsk played champions of northwest Poland A-Classes (Legia Poznań), northeast Poland A-Classes (Śmigły Wilno) and southeast Poland A-Classes (Junak Drohobycz). Out of the four teams, three were going to be promoted. Śląsk managed to play only two games - 0-0 in Drohobycz and 2-1 at home with Śmigły Wilno. Then, on September 1, 1939, Germany attacked Poland and all matches were suspended.
