Expulsion of Poles by Germany

The expulsion of Poles by Germany was a series of forced displacements, deportations, and ethnic cleansing campaigns targeting Polish populations by German authorities, particularly during the 20th century. These actions occurred primarily during two key periods: under Nazi Germany during World War II, and earlier during the German Empire’s nationalist policies.
