Nuremberg and War crimes trials


War Crimes Trials, trials of persons charged with criminal violation of the laws and customs of war and related principles of international law. After World War II the phrase referred usually to the trials of German and Japanese leaders in courts established by the victorious Allied nations.

The most important of these trials were held in Nuremberg, Germany, under the authority of two legal instruments. One, the so-called London Agreement, was signed by representatives of the United States, Great Britain, France, and the USSR in London on August 8, 1945; the other, Law No. 10, was promulgated by the Allied Control Council in Berlin on December 20, 1945.

The London Agreement provided for the establishment of the International Military Tribunal, composed of one judge and one alternate judge from each of the signatory nations, to try war criminals. Under the London Agreement, the crimes charged against defendants fell into three general categories: crimes against peace, that is, crimes involving the planning, initiating, and waging of aggressive war; war crimes, that is, violations of the laws and customs of war as embodied in the Hague Conventions and generally recognized by the military forces of civilized nations; and crimes against humanity, such as the extermination of racial, ethnic, and religious groups and other large-scale atrocities against civilians. Nuremberg Trials

On October 18, 1945, the chief prosecutors lodged an indictment with the tribunal charging 24 individuals with a variety of crimes and atrocities, including the deliberate instigation of aggressive wars, extermination of racial and religious groups, murder and mistreatment of prisoners of war, and the murder, mistreatment, and deportation to slave labor of hundreds of thousands of inhabitants of countries occupied by Germany during the war.

Among the accused were the Nationalist Socialist leaders Hermann Göring and Rudolf Hess, the diplomat Joachim von Ribbentrop, the munitions maker Gustav Krupp von Bohlen und Halbach, Field Marshal Wilhelm Keitel, Grand Admiral Erich Raeder, and 18 other military leaders and civilian officials. Seven organizations that formed part of the basic structure of the Nazi government were also charged as criminal. These organizations included the SS (Schutzstaffel “Defense Corps”), the Gestapo (Geheime Staatspolizei, “Secret State Police”), the SA (Sturmabteilung, “Storm Troops”), and the General Staff and High Command of the German armed forces.

The trial began on November 20, 1945. Much of the evidence submitted by the prosecution consisted of original military, diplomatic, and other government documents that fell into the hands of the Allied forces after the collapse of the German government.

The judgment of the International Military Tribunal was handed down on September 30-October 1, 1946. Among notable features of the decision was the conclusion, in accordance with the London Agreement, that to plan or instigate an aggressive war is a crime under the principles of international law. The tribunal rejected the contention of the defense that such acts had not previously been defined as crimes under international law and that therefore the condemnation of the defendants would violate the principle of justice prohibiting ex post facto punishments. It also rejected the contention of a number of the defendants that they were not legally responsible for their acts because they performed the acts under the orders of superior authority, stating that “the true test . . . is not the existence of the order but whether moral choice (in executing it) was in fact possible.”

With respect to war crimes and crimes against humanity, the tribunal found overwhelming evidence of a systematic rule of violence, brutality, and terrorism by the German government in the territories occupied by its forces. Millions of persons were destroyed in concentration camps, many of which were equipped with gas chambers for the extermination of Jews, Gypsies, and members of other ethnic or religious groups. Under the slave-labor policy of the German government, at least 5 million persons had been forcibly deported from their homes to Germany. Many of them died because of inhuman treatment. The tribunal also found that atrocities had been committed on a large scale and as a matter of official policy. Of the seven indicted organizations, the tribunal declared criminal the Leadership Corps of the National Socialist Party, the SS, the SD (Sicherheitsdienst, “Security Service”), and the Gestapo.

Twelve defendants were sentenced to death by hanging, seven received prison terms ranging from ten years to life, and three, including the German politician and diplomat Franz von Papen and the president of the German Central Bank Hjalmar Horace Greeley Schacht, were acquitted. Those who had been condemned to death were executed on October 16, 1946. Göring committed suicide in prison a few hours before he was to be executed.

After the conclusion of the first Nuremberg trial, 12 more trials were held under the authority of Control Council Law No. 10, which closely resembled the London Agreement but provided the war crimes trials in each of the four zones of occupied Germany.

About 185 individuals were indicted in the 12 cases. Those indicted included doctors who had conducted medical experiments on concentration camp inmates and prisoners of war, judges who had committed murder and other crimes under the guise of the judicial process, and industrialists who had participated in the looting of occupied countries and in the forced-labor program. Other persons indicted included SS officials, who had headed the concentration camps, administered the Nazi racial laws, and carried out the extermination of Jews and other groups in the eastern territories overrun by the German army; and high military and civilian officials who bore responsibility for these and other criminal acts and policies of the Third Reich. A number of doctors and SS leaders were condemned to death by hanging, and approximately 120 other defendants were given prison sentences of various durations; 35 defendants were acquitted.

Tokyo and Other Trials

Another war crimes trial was held under international authority in Tokyo. The International Military Tribunal for the Far East was constituted under the authority of a charter promulgated on January 19, 1946, by General Douglas MacArthur, supreme commander for the Allied Powers. Many provisions of the charter were adapted from those of the London Agreement. The Tokyo trial opened on May 3, 1946, and held its final session on November 12, 1948. The conclusions reached by the 11-nation tribunal were generally parallel to those embodied in the judgment given in Nuremberg. Of the 28 defendants named in the indictment, 7 were condemned to death by hanging, and all but 2 of the others were sentenced to life imprisonment.

Many other trials of alleged war criminals were held by tribunals constituted by the governments of the countries that had been occupied in whole or in part by Germany or Japan during World War II. In addition, military tribunals in the British and American zones of occupation in Germany tried Germans under the laws of war. Numerous trials of Japanese military officers were held also in the Philippines and Australia and by American military courts on Japanese territory. For the most part, these trials were based on alleged violations of the laws and customs of war and did not involve the crimes against peace and crimes against humanity that had constituted an important part of the Nuremberg proceedings. Alleged war criminals were being brought to trial long after the end of World War II. In 1960 the Nazi official Adolf Eichmann, who had been a member of the German SS and an organizer of anti-Semitic activities, was captured as a war criminal in Argentina by Israeli agents. Taken to Jerusalem, he was tried and condemned the following year and executed in 1962.


The Nuremberg and other war crimes trials were a notable step in the evolution of international penal law. The standing of the trials suffered sharply, however, because the proceedings were carried out under auspices of victorious powers and the charges were brought only against the nationals of vanquished Germany and Japan. Nevertheless, the principles applied in the Nuremberg and Tokyo trials helped to strengthen international law and the judicial mechanisms for its enforcement. Also, the United Nations has ratified the general principles of the trials.
