Upon his release Hitler quickly set about rebuilding his moribund party, vowing to achieve power only through legal political means thereafter. The Nazi Party’s membership grew from 25,000 in 1925 to about 180,000 in 1929. Its organizational system of gauleiters (“district leaders”) spread through Germany at this time, and the party began contesting municipal, state, and federal elections with increasing frequency.
As the German leader (Führer) of Nazi Germany, Hitler began moving Nazi armies into neighboring countries. When Germany attacked Poland, World War II started. Western countries like France, Belgium, and the Netherlands were occupied and to be treated by Germany as colonies. However, in Eastern countries, such as Poland and the Soviet Union, the Nazis planned to kill or enslave the Slavic peoples, so that German settlers could take their land.
Criterion (vi): Auschwitz Birkenau, monument to the deliberate genocide of the Jews by the German Nazi regime and to the deaths of countless others, bears irrefutable evidence to one of the greatest crimes ever perpetrated against humanity. It is also a monument to the strength of the human spirit which in appalling conditions of adversity resisted the efforts of the German Nazi regime to suppress freedom and free thought and to wipe out whole races. The site is a key place of memory for the whole of humankind for the Holocaust, racist policies and barbarism; it is a place of our collective memory of this dark chapter in the history of humanity, of transmission to younger generations and a sign of warning of the many threats and tragic consequences of extreme ideologies and denial of human dignity.
