Nazi ideology in the context of "Untermenschen"

The Generalplan Ost (German pronunciation: [ɡenəˈʁaːlˌplaːn ˈɔst]; lit. 'Master Plan for the East'), abbreviated GPO, was Nazi Germany's plan for the settlement and "Germanization" of captured territory in Eastern Europe, involving the genocide, extermination and large-scale ethnic cleansing of Slavs, Eastern European Jews, and other indigenous peoples of Eastern Europe categorized as "Untermenschen" in Nazi ideology. The campaign was a precursor to Nazi Germany's planned colonisation of Central and Eastern Europe by Germanic settlers, and it was carried out through systematic massacres, mass starvations, chattel labour, mass rapes, child abductions, and sexual slavery.

Generalplan Ost was only partially implemented during the war in territories occupied by Germany on the Eastern Front during World War II, resulting indirectly and directly in the deaths of millions by shootings, starvation, disease, extermination through labour, and genocide. However, its full implementation was not considered practicable during major military operations, and never materialised due to Germany's defeat. Under direct orders from Nazi leadership, around 11 million Slavs were killed in systematic violence and state terrorism carried out as part of the GPO. In addition to genocide, millions more were forced into slave labour to serve the German war economy.

Alfred Ernst Rosenberg (12 January [O.S. 31 December 1892] 1893 – 16 October 1946) was a Baltic German Nazi theorist, theologian, ideologue and convicted war criminal. Rosenberg was first introduced to Adolf Hitler by Dietrich Eckart, and he held several important posts in the Nazi government. He was the head of the NSDAP Office of Foreign Affairs during the entire rule of Nazi Germany (1933–1945), and led Amt Rosenberg ("Rosenberg's bureau"), an official Nazi body for cultural policy and surveillance, between 1934 and 1945. During World War II, Rosenberg was the head of the Reich Ministry for the Occupied Eastern Territories (1941–1945). He helped direct the mass murder of the Slavs. After the war, he was convicted of crimes against peace; planning, initiating and waging wars of aggression; war crimes; and crimes against humanity at the Nuremberg trials in 1946. He was sentenced to death by hanging and executed on 16 October 1946.

The author of a seminal work of Nazi ideology, The Myth of the Twentieth Century (1930), Rosenberg is considered one of the main authors of key Nazi ideological creeds, including its racial theory and its hatred of the Jewish people, the need for Lebensraum, abrogation of the Treaty of Versailles, and opposition to what was considered "degenerate" modern art. He was also known for his hatred and rejection of what he regarded as "negative" Christianity; however, he played an important role in the development of German nationalist Positive Christianity, which rejected the Old Testament.

The Deutsches Jungvolk in der Hitlerjugend (pronounced [ˈdɔʏtʃəs ˈjʊŋfɔlk]; DJ, also DJV; German for "German Youngsters in the Hitler Youth", lit. 'German Young People') was the separate section for boys aged 10 to 14 of the Hitler Youth organisation in Nazi Germany. Through a programme of outdoor activities, parades and sports, it aimed to indoctrinate its young members in the tenets of Nazi ideology. Membership became fully compulsory for eligible boys in 1939. By the end of World War II in Europe, some had become child soldiers. After the end of the war in 1945, both the Deutsches Jungvolk and its parent organization, the Hitler Youth, ceased to exist.

The Barmen Declaration or the Theological Declaration of Barmen 1934 (German: Die Barmer Theologische Erklärung) was a document adopted by Christians in Nazi Germany who opposed the German Christian movement. In the view of the delegates to the Synod that met in the city of Wuppertal-Barmen in May 1934, the German Christians had corrupted church government by making it subservient to the state and had introduced Nazi ideology into the German Protestant churches that contradicted the Christian gospel.
