I want to know the answer to the following question:
How long did many of the Germans live in the eastern Europe countries before being expelled?
All the background I'm provided with is that "Germans were also forced to leave the former eastern territories of Germany, which were annexed by Poland (Silesia, Pomerania, parts of Brandenburg and southern part of East Prussia) and the Soviet Union (northern part of East Prussia).". Is that enough to answer the question?
Answer: no
