At the end of [[World War I]], the [[Treaty of Versailles]] awarded the province and city of Posen to the new Poland. The local German populace were forced to acquire Polish citizenship or leave the country, forfeiting all property to the Polish State. This led to a wide emigration of the ethnic Germans of the town's population – the town's German population decreased from 65,321 in 1910 to 5,980 by 1926 and further to 4,387 in 1934.<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>

In the interwar [[Second Polish Republic]], the city again became the capital of [[Poznań Voivodeship]]. Poznań's university, today called [[Adam Mickiewicz University]], was founded in 1919, and in 1924 the [[Poznań International Fair]] began. In 1929, the fair site was the venue for a major National Exhibition (''Powszechna Wystawa Krajowa'', popularly ''PeWuKa'') marking the tenth anniversary of independence; organized on a space of 650,000 square metres it attracted around 4.5&nbsp;million visitors. In the 1930s, the fair ranked as European fourth largest organiser of international trade events.<ref>{{Cite web|date=2021-09-29|title=Snapshots frozen in time.
