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.
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.
For example, Legia was a military sport club (Wojskowy Klub Sportowy).
After the 1927 season, Jutrzenka Kraków was relegated and Śląsk Świętochłowice won promotion, but since Cracovia came to terms with the League, this renowned team was automatically added.
Wisła Kraków again turned out to be the best, with Warta Poznań finishing on the second position.
Relegated were 3 teams - Hasmonea Lwów, Śląsk Świętochłowice, and TKS Toruń.
Three sides were relegated and one (Garbarnia Kraków) promoted, which again meant uneven number of teams - 13.
However, in December 1929, after the games had been finished, PZPN changed the result of the Klub Turystow Łódź - Warta Poznań match.
Originally, Łódź 's side won 2-1, however it was verified as 0-3 in favor of Warta, as reportedly, the scorer of Klub Turystow's both goals was not permitted to have appeared on the field.
This controversial decision added two points to Warta and deprived Garbarnia of the championship.
After nine years, the first, historic champion of Poland, Cracovia, regained the title.
Its main rival, Wisła Kraków, finished with just point less, and Legia Warszawa was third.
Finally, Garbarnia Kraków won the championships, this time without any doubts.
Also, Legia Warszawa for another time was third, demoted was a newcomer = Lechia Lwów.
Cracovia again returned to the top, just ahead of another renowned team, Pogoń Lwów.
In this season, PZPN decided to divide the League into two groups - Eastern and Western each of them consisted of 6 teams.
The League returned to its original form, with one group, covering the whole country.
Ruch Chorzów again proved its quality, winning the games, Cracovia was second.
Second newcomer, Garbarnia Kraków, won a special tournament, thus saving its spot in the League.
Sensational was relegation of one of the most renowned teams of Polish football, Cracovia.
Starting in this year, the League shrank to ten teams and this remained until the outbreak of World War II.
Cracovia marked its return by winning the League, second was AKS Chorzów.
This time, Ruch Chorzów returned, winning the games, ahead of Warta Poznań and Wisła Kraków.
One newcomer, Śmigły Wilno, was relegated, another - Polonia Warszawa, was fourth.
Games of this season were not finished, due to the outbreak of World War II.
On August 31, 1939, Ruch Chorzów was first, second was Wisła Kraków, with two games less.
Newcomers - Garbarnia Kraków and Union Touring Łódź were respectively eight and tenth.
