Rosenberg was the head of the Nazi Party's foreign affairs department (1933). In 1940, he established an organization (Einsatzstab Rosenberg) whose mission was to loot and confiscate cultural treasures from all over Europe and bring them to Germany. 

As Reich Minister for the Occupied Eastern Territories (1941), Rosenberg had some responsibility for German policy in occupied areas of the Soviet Union, including the annihilation of Soviet Jews and the deportation of millions of Soviet civilians for forced labor in Germany. 

Tried as a major Nazi war criminal before the International Military Tribunal (IMT) at Nuremberg in 1945, Rosenberg was found guilty on all four counts (conspiracy, crimes against peace, war crimes, and crimes against humanity) and sentenced to death. He was hanged on October 16, 1946.
