When in 1908 the German Reichstag passed legislation mandating that all public meetings were to be held in German, the ZZP resorted to all sorts of creative subterfuges to express its total outrage at this severe restriction of its freedom of speech.
To be sure, the existence of the ZZP as a Polish union on German soil did lead to a number of decisions clashing with either its national mission or its class appeal.
The qualitative leap of the ZZP from an organization combining class and national appeal towards a group consciously choosing Polish nationalism over working class solidarity occurred with the recreation of a Polish state.
Starting in 1904 the ZZP began organizing work in Poznania.
Compounding this reorientation of ZZP work was the desire of many Poles living in the Ruhr to return to their native lands after independence, though here their desire to return soon began to clash with the Polish state's inability to cope with large numbers of would-be returnees.
