Germany 1933-1939: Mounting Human Rights Violations

As the concentration camp system took root, political dissenters and civilian "undesirables" (Jews, gypsies, blacks, etc.) were stripped of rights and later sent to camps to be used as slaves or be executed - this was considered a major crime against humanity.

The Nuremberg Laws

The Nuremberg laws officially and severely limited Jewish rights and citizenship; Nuremberg Trials defendants Wilhelm Frick and Hermann Göring were influential in the writing and passing of the laws. The limitation of certain groups' rights was considered a crime against humanity.

"Marriages between Jews and subjects of the state of German or related blood are forbidden. Marriages nevertheless concluded are invalid, even if concluded abroad to circumvent this law." - Article 1, Law for the Protection of German Blood and German Honor

"A Reich citizen is a subject of the state who is of German or related blood, and proves by his conduct that he is willing and fit to faithfully serve the German people and Reich. [...] The Reich citizen is the sole bearer of full political rights in accordance with the law." - Article 2, Reich Citizenship Law

Expanding the Concentration Camp System

"Whoever in the future raises a hand against a representative of the National Socialist movement or of the State must know that he will lose his life in a very short while." - IMT Defendant Hermann Göring 
Camps were built throughout Nazi territories and used for forced labor and extermination of Jews, racial minorities, and political prisoners. These severe violations of human rights were the most prominent crime against humanity tried at the Nuremberg trials.
