Alfred Ernst Rosenberg (12 January [O.S. 31 December 1892] 1893 – 16 October 1946) was a Baltic German Nazi theorist and ideologue. 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). 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, persecution of the Jews, Lebensraum, abrogation of the Treaty of Versailles, and opposition to what was considered "degenerate" modern art. He is known for his opposition to Christianity, having played an important role in the development of German nationalist Positive Christianity. Source: Wikipedia (en)
