No Polish family was unaffected by the World War II' s death toll. Over 85 percent of Warsaw was destroyed in WW II.
Out of the 6 million Poles that died in the WW II, half were Polish Jews, and from the 6 million Jews that vanished in the Holocaust, half were Polish Citizens (before World War II, 3,300,000 Jewish people lived in Poland. Poland was the center of the European Jewish world).

The Warsaw Ghetto Uprising was the largest single revolt by Jews during World War II in the largest of all the Jewish ghettos in Nazi-occupied Europe with over 400,000 Jews imprisoned in an area of 3.4 sq. km.

To date over 6,700 Poles have been awarded the title of Righteous Among the Nations by the State of Israel - more than those by any nation by far.
