would it not have been Posen...a German city...up till 1945..?
Given that its one of the oldest most powerfull polish cities hardly, also Poznań returned to Poland between 1920-39.
I just read up on the history of Poznan...jeez , it changed hands so many times in its history...
Many times? It was Polish untill the partitions (Something like 800 years) then Germans invaded it, it was in Prussia for 123 years, returned to Poland for 19 years, again German for 5 years and then returned to Poland for 65 years.
So it was a polish city for 865 years out of its 1000 years old existance and Germans invaded it twice so its hardly "a lot of times" most of Poznań is/was also developed by Poles, even under Prussia since it was next to Lwów, Kraków and Warsaw one of the hubs of polish culture.
The city has a couple of dozen of German buildings and thats is, it pisses me off to no end when people claim Germans developed Poznań or made it what it is today when its a 100% Polish city and 100% Polish achievement.
You can still see the lingering Prussian mentality here, things just work and the job gets done!
Thats not "Prussian mentality" Poznań was one of the most developed urban hubs of Poland and unlike other cities wars rarely disrupted its social structure, no wonder local society has its sh*t together, it has nothing to do with Prussia or "Prussian mentality" though.
