Did Poland sign an agreement to allow German language to the native population of Pomerania , Silesia, West and East Prussia and for them to be able to change their names back to their original German names again ? ? ? .
---
German native population (living before World War II in Pomerania, Silesia etc.) of western and northwesternparts of Poland was mostly deported to Germany after World War II. Very few German-speaking people live in Poland nowadays (less than 1 %). According to Polish law everyone has right to change her/his name if she/he proves that she/he has important reason to do so - for example if he wants to have German name. In Poland everyone has right to speak in his native language, every ethnic minority has right to establish their schools, there are also schools for German minority. Poland has signed many international treaties which guarant human rights, including rights of ethnic minorities.
