Jews, Gypsies, Negroes and their bastard offsprings were the people that were effected by the Nuremberg Laws as non-Aryan, basically anyone who was not Indo-European.

All non-European people were seen as non-Aryan.

Japanese were seen as "honorary Aryan", and so was the Arab Mufti Haj Amin al-Husseini and some Jews.

The hierarchy was simple the Germanic Ubermenschen were the master race and all other Europeans were Aryans beneath the Germanic people.

The Slavic Untermenschen myth was created by the Communists after the war, the Nazis never called Slavs "untermensch" and many fought on the Nazis side against the Jewish Bolsheviks as well as many Nazi documents showing Slavs as "Aryan". Slavs were considered Aryan by the Nazis and sexual relations between Germans and Slavs was not forbid.

Whilst the Nazis did use anti-Slavic propaganda to dehumanize the opponent in the war they were no racial hatred against the Slavs than any other non-Germanic groups such as Balts and Celts neither. Many websites and books repeat that the Nazis considered Slavs to be untermenschen and non-Aryan but this is not true. People often confuse 'Aryan' with 'master race' the Nazis used the term Aryan differently and when used as the master race it was only meant for Germanic people only.

Remember, the Slavs were supporting and being ruled by Communism/Bolshevism which was Jewish according to the Nazis and the Nazis wanted lebensraum "living space" in Eastern Europe so remember you can see why they called them uncultured. Hitler himself never really "hated" Slavs as to speak, he just hated the fact that Austria was being overruled in the Austro-Hungarian empire by the Czechs, Poles and other Slavs and called it the Slavicification of Austria which he did not want as he seen it as the de-Germanisation of Austria.

Hitler was first a German nationalist and was pan-German all the way but he also was a pan-European leader who did not have any racial hatred against Slavs and they were considered Aryan. In fact, before the war Hitler initially wanted Poland as an alliance against the Soviet Union. Also, after the invasion of Poland there was an "Aryan side" which was mostly of Poles and the German minority and others.

Of course one must remember many truths are often ignored about the Nazis since history is written by the victors.
