After World War I, the use of German was suppressed and discouraged due to the anti-German sentiment, but nevertheless it did not inflict any lasting damage to its Sprachraum nor its lingua franca status in some areas. However, after World War II, territorial changes implemented by the Allies practically removed the German language from large parts of Central and Eastern Europe that were inhabited by German-speaking populations beginning in the 12th century. It contributed to moribundness and extinction of some local dialects like Silesian German, High Prussian or East Pomeranian dialects.
