Prussia is definitely NOT part of Russia. All Germans from Pommerania, East Prussia, West Prussia, Schlesien, and Brandenburg were called Prussians. Prussians are GERMAN.
lol..depends what period of history we talking about.
prussians belong to baltic group,same as Estonians and Finnish people.there were last pagans of Europe,conquered and germanized by teutonic order.
after TO conquered them,they converted them to Catholicism and started process of germanization. which was gradual.even in 19 century old prussian language was still present in rural areas.
prussians were not german tribes..prussian are germanized balts
silezians were partly germanized slavs..from silezia came idea of creating polish state..it was birthplace of Poland. area was settled by germans after mongol invasion and gradually germanized.ahhh..cant be bothered talking to ignorants
