Rosenberg built on the works of Arthur de Gobineau Houston Stewart Chamberlain and Madison Grant as well as the beliefs of Hitler. The organization of these administrative territories led to conflict between Rosenberg and the SS over the treatment of Slavs under German occupation. At the Nuremberg Trials he claimed to be ignorant of the Holocaust despite the fact that Leibbrandt and Meyer were present at the Wannsee conference.
He is also known for his rejection of Christianity having played an important role in the development of Positive Christianity which he intended to be transitional to a new Nazi faith. Rosenberg was first introduced to Adolf Hitler by Dietrich Eckart; he later held several important posts in the Nazi government. At Nuremberg he was tried sentenced to death and executed by hanging as a war criminal.
