After the war, Bydgoszcz was assigned to the [[Second Polish Republic|recreated Polish state]] by the 1919 [[Versailles Treaty]]. Now officially Bydgoszcz again, the city belonged to the [[Poznań Voivodeship (1921–1939)|Poznań Voivodeship]]. The local populace was required to acquire Polish citizenship or leave the country. This led to a drastic decline in ethnically [[German minority in Poland|German residents]], whose number within the town decreased from over 40.000 in 1910 to 11,016 in 1926.<ref>{{cite book|url=https://books.google.com/books?id=KVg_tMs_ZPIC&q=adelnau&pg=PA365|title=Polens Politik gegenüber seiner deutschen Minderheit 1919–1939|first1=Albert S.|last1=Kotowski|page=56|publisher=Forschungsstelle Ostmitteleuropa, [[University of Dortmund]] |year=1998 |language=de|isbn=3-447-03997-3}}</ref> A Nazi German youth organization was subsequently founded, which distributed [[Propaganda in Nazi Germany|Nazi propaganda]] books from Germany among the German minority.{{sfn|Wardzyńska|2009|p=23}}

The city's boundaries were greatly expanded in 1920 to include the surrounding suburbs of Okole, Szwederowo, Bartodzieje, Kapuściska, Wilczak, Jachcice and more, which made Bydgoszcz the third largest city in  the [[Second Polish Republic]]<ref>Infrastruktura i gospodarka komunalna.
