So just because someone has a German name then that makes them German?
Kopernik never had a German name,
ever. He never signed a single document with his name in German in his life, he always used Copernicus which is in latin.
Copernicus is a latinised version, not a German name, many popular German media intentionaly omit the fact to impress their assumption that he was German because to the average Joe Coppernicus sounds kinda German, except its not.
There's many assumptions (usually biased) by German scholars, or forwarding how German editors signed his book as proof but Kopernik in person never signed a document other then in Latin.
Copernicus' ethnicity is definitely 100% Polish.
No its not, its 50% Polish since only his father was Polish but Kopernik himself during his life chose his citizenship and allegiance, he chose to side with Poles and fight against Germans there's nothing more telling then that.
Copernicus lived the way many Poles did. He studied at Polish and then Italian schools which is what mostly Poles did at that time. Germans did not do that.
No, Germans lived in caves and sacrificed babies to evil dark gods, it would help your position if you werent so bloody ignorant you know.
A) Copernicus' Uncle Lucas Watzenrode the alleged "German" uncle went to the few Polish schools there were at the time and recommended Copernicus go to Polish schools (in the beginning of the book)
Watznerode like Kopernik chose allegiance to Polish king but unlike Kopernik he was a full German ethnically speaking, lets not be biased.
