International Military Tribunal in the context of "Aftermath of World War II"

International criminal law (ICL) is a body of public international law designed to prohibit certain categories of conduct commonly viewed as serious atrocities and to make perpetrators of such conduct criminally accountable for their perpetration. The core crimes under international law are genocide, war crimes, crimes against humanity, and the crime of aggression.

Classical international law governs the relationships, rights, and responsibilities of states. After World War II, the Charter of the International Military Tribunal and the following Nuremberg trial revolutionized international law by applying its prohibitions directly to individuals, in this case the defeated leaders of Nazi Germany, thus inventing international criminal law. After being dormant for decades, international criminal law was revived in the 1990s to address the war crimes in the Yugoslav Wars and the Rwandan genocide, leading to the establishment of a permanent International Criminal Court in 2001.

Extermination is a crime against humanity that consists of "the act of killing on a large scale". To be convicted of this crime, someone must play a role in a sufficiently-large scale killing of civilians, including those carried out by "the intentional infliction of conditions of life... calculated to bring about the destruction of part of a population". It was first prosecuted at the International Military Tribunal in Nuremberg, and was included in the enumerated crimes against humanity in the Rome Statute.

The aftermath of World War II saw the rise of two global superpowers, the United States and the Soviet Union. The aftermath of World War II was also defined by the rising threat of nuclear warfare, the creation and implementation of the United Nations as an intergovernmental organization, and the decolonization of Asia, Oceania, South America and Africa by European and East Asian powers, most notably by the United Kingdom, France, and Japan.

Once allies during World War II, the U.S. and the Soviet Union became competitors on the world stage and engaged in the Cold War, so called because it never resulted in overt, declared total war between the two powers. It was instead characterized by espionage, political subversion and proxy wars. Western Europe was rebuilt through the American Marshall Plan, whereas Central and Eastern Europe fell under the Soviet sphere of influence and eventually behind an "Iron Curtain". Europe was divided into a U.S.-led Western Bloc and a Soviet-led Eastern Bloc. Internationally, alliances with the two blocs gradually shifted, with some nations trying to stay out of the Cold War through the Non-Aligned Movement. The Cold War also saw a nuclear arms race between the two superpowers, and part of the reason that the Cold War never became a "hot" war was that the Soviet Union and the United States had nuclear deterrents against each other, leading to a mutually assured destruction standoff.

United States of America v. Karl Brandt, et al., commonly known as the Doctors' Trial, was the first of the twelve "Subsequent Nuremberg trials" for war crimes and crimes against humanity after the end of World War II between 1946 and 1947. The accused were 20 physicians and 3 SS officials charged for their involvement in the Aktion T4 programme and Nazi human experimentation.

The Doctors' Trial was held by United States authorities at the Palace of Justice in Nuremberg in the American occupation zone before US military courts, not before the International Military Tribunal. Seven of the accused were sentenced to death by hanging, five were sentenced to life imprisonment, four were given prison sentences from 10 to 20 years, and seven were acquitted.

The Ministries Trial (or, officially, the United States of America vs. Ernst von Weizsäcker, et al.) was the eleventh of the twelve trials for war crimes the U.S. authorities held in their occupation zone in Germany in Nuremberg after the end of World War II. These twelve trials were all held before U.S. military courts, not before the International Military Tribunal, but took place in the same rooms at the Palace of Justice. The twelve U.S. trials are collectively known as the "subsequent Nuremberg trials" or, more formally, as the "Trials of War Criminals before the Nuremberg Military Tribunals" (NMT).

This case is also known as the Wilhelmstrasse Trial, so-named because both the Reich Chancellery and the German Foreign Office were located at the Wilhelmstrasse, a street in Berlin that was often used as a metonym for overall German governmental administration. The defendants in this case were officials of various Reich ministries, facing various charges for their roles in Nazi Germany and thus their participation in or responsibility for the numerous atrocities committed both in Germany and in occupied countries during the war.
