Ethnic cleansing
During ancient and medieval history, Jewish people were victims of ethnic cleansing in many countries.  For example, around 1290 AD, King Edward I of England ordered all of the Jews in the country to leave.  Hundreds of elderly Jews were executed.  Next, France and some German states did the same.  Finally, in 1492, Spain ordered its Jews to convert to Catholicism or leave the country.  Any Jew who stayed in the country would be executed without a trial.  Between 40,000 and 100,000 Jews were forced to leave Spain.
