Poles have existed for a millennia, the first Polish state started in 966 AD as the Kingdom of Poland with the adoption of Western Christianity by the first Polish king. Maybe the idea of a nation hadn't been formed yet, but Poland had. The Polish word for Germany is "Niemec" or land of mutes, because they were unintelligible.
Why would anyone make that argument? Claiming Poznań as German reeks of irredentism. Germanic != German. Do germans still claim the cities of other Germanic countries and former lands like Austria, Czechia, Denmark, Norway, Belgium, Netherlands, Luxembourg and the Baltics as German?
