The exceptions are Klasa A in the Podlaskie Voivodeship, where it is the lowest tier of the game (no Klasa B),[1] and in the Greater Poland Voivodeship, where it is the eighth tier of the football hierarchy, due to the existence of V liga in this region.
[2] In 1920–1927, Klasa A was the highest level of regional competitions, class A champions met in the finals of the non-league Polish Championships.
In 1928, the league joined the Polish Football Association and Klasa A became the second tier of the competition – its champions were promoted as a result of multi-stage play-offs.
It regained its importance shortly after the Second World War in 1946–1947, when the non-league Polish Championships were played again.
In the following years, the successively created or liquidated leagues (second, third, fourth, fifth) resulted in the fact that Klasa A fell in the hierarchy of games in Poland.
