The I.G. Farben Trial, the sixth subsequent Nuremberg proceeding, was tried by the Military Tribunal VI, which had been created by the U.S. Military Government for Germany on August 8, 1947. An indictment was filed on May 3 naming twenty-four defendants, all in the IG Farben industrial concern, and listing five counts: the planning, preparation, initiation, and waging of wars of aggression and invasions of other countries; committing war crimes and crimes against humanity through the plunder and spoliation of public and private property in countries and territories that came under German occupation; committing war crimes and crimes against humanity through participating in the enslavement and deportation for slave labor of civilians from German-occupied territories and of German nationals; participation by defendants Christian Schneider, Heinrich Buetefisch, and Erich von der Heyde in the SS, a recently-declared criminal organization; and participation in a common plan or conspiracy to commit crimes against peace.
