Voici quelques informations sur la Prusse avant la conquète teutonne :
Cette carte représente en fait l'aire linguistique des langues baltes. Bien sûr, aujourd'hui, on peut enlever le vieux prussien disparu depuis des sicèles. Mais on voit quand même que les prussiens étaient bien un peuple balte.
Quelques informations sur la langue prussienne.

Old Prussian was westernmost of all Baltic tongues, this is why it was subject to constant invasions from the West. To convert Prussians into Christianity, Poles and Teutons conquered the land in the 13th century. The language was suppressed by German and Polish. Only during the Reformation several short texts were written in Old Prussian - two Catechisms and the Enchridion (from 1545 to 1561). A few small dictionaries were composed in the 17th century, but by the end of the century the language was no longer spoken, it became extinct.
Today people of Germany, Poland, Lithuania and the USA work on reviving the language - communities are established where people learn Old Prussian history, culture and language itself.

Quant au génocide prussien, au vrai cette fois, je pense qu'il eut lieu en 1945.
