The historical events, political decisions, economic implications, social processes and personal choices that took place in Nazi Germany from 1933 to 1945 and led to the concentration camps and the planned extermination of Jews, Gypsies, Jehovah's Witnesses, Freemasons, Soviet prisoners and homosexuals are hard to disentangle.

Focusing on such a complex process is a challenge as it requires looking into the darkest side of mankind and Philosophy, with its claim for truth, clear language and complete explanations, proves essential in this task; the first step is to look into the facts with open eyes and an unbiased mind.

Germany was defeated in the First World War on 11st November 1918, the Wall Street crisis of 1929 destroyed what remained of the German economy, Germans were desperate, with no hope for their future and no trust in democracy; in 1933 the Nazi Party and its leader Adolf Hitler were elected by the majority.
The political manifest of the Nazi Party was exposed in Mein Kampf (My Struggle) written by Hitler in 1925: Germans, the "master race" (Herrenvolk), were humiliated during the First World War by a hidden conspiracy led by Jews; Germany must regain its historical position and rule over the sub-humans (Untermenschen). All sub human races (Jews, Gypsies, Armenians, Poles, Serbs, Belarusians, Russians) shall be used by Germans as slaves and afterwards exterminated (for example by starvation, trivial and sadistic scientific experiments or gas chambers). In 1933 concentration camps were born in Germany following the enactment of discriminatory and anti-Semitic laws, which led in 1942 to find, through the large-scale deportation of Jews to those camps, the "final solution" to the "Jewish question". The Holocaust, or the Shoah, was strictly pursued in the Cooperative indifference of German people.
