September 1939, Nazi Germany invades Poland starting WW2 unleashing six years of unimaginable death and suffering upon the world, with a total death-toll over 70 million people. Motivated by twisted concepts of racial cleansing, between 1939 and 1945 the SS killed between 11 and 14 million people in ghettos, mass executions and concentration camps. The largest being the extermination camp complex of Auschwitz-Birkenau in Poland, where appromately 1.4 million people were either starved to death or gassed before being cremated on an industrial scale.
