In the years 1921–1926, the football championships were organized in a non-league way. Firstly, there were regional games, then 9 champions of those regions were divided into 3 groups - western, southern and northern (with 3 teams in each) and finally, there were champions of these groups playing each other in the big finale.
However, this was not practical and some time in early 1927, representatives of several Polish clubs decided to follow other European countries (with the exception of Germany) and organize the all-national Polish Football League. This proposal was strongly opposed by PZPN (Polish Football Association) and by one of strongest football organizations of the country - Cracovia, whose director was also the director of PZPN.
Nevertheless, even without PZPN's support, the teams decided to go on with their idea. The League was officially formed on March 1, 1927 and on April 3, 1927 first games of the 14-team League took place. Originally, a spot in it was reserved for Cracovia, but after its refusal, it was given to Jutrzenka Kraków. The first, historic champion of the League became Wisła Kraków, but only after a fierce competition with a German-minority team 1. FC Katowice. Relegated was only one team, this was Jutrzenka.
On December 18, 1927, PZPN post factum officially announced that champion of the League was champion of Poland, and this automatically ended the conflict. It also meant that Cracovia would enter the League.
This is the list of teams which in November 1927 finished the games (notice: in interbellum Poland, games of the League were held in spring-autumn order):
3. Warta Poznań
4. Pogoń Lwów
7. Łódź
