The Holocaust trials are the criminal proceedings, running from 1945 to the present, that have prosecuted Nazi leaders, officials, doctors, judges, industrialists, and camp personnel for the persecution and mass murder of Jews and other targeted groups during the Second World War. They began with the International Military Tribunal at Nuremberg and continued through Allied zone courts, Israel’s prosecution of Adolf Eichmann, decades of West German domestic cases, and a final wave of prosecutions of elderly former camp guards that is still underway in Germany. Across those eight decades, the courts built something that had not existed before: a body of law holding individuals personally responsible for atrocities carried out under state authority.
The International Military Tribunal at Nuremberg
The first and most consequential proceeding rested on the London Agreement of August 8, 1945, signed by the United States, Great Britain, the Soviet Union, and France. The agreement created the tribunal and annexed a charter defining its jurisdiction, structure, and crimes.1The Avalon Project. London Agreement of August 8th 1945 Each of the four signatories appointed one judge and one alternate under Article 2 of the Charter.2The Avalon Project. Charter of the International Military Tribunal
The indictment named 24 defendants under four counts: conspiracy to wage aggressive war, crimes against peace, war crimes, and crimes against humanity. It also sought to have several Nazi bodies declared criminal, among them the SS, the Gestapo, the SD, the SA, and the Leadership Corps of the Nazi Party.3Yale Law School. Nuremberg Trial Proceedings Vol. 1 – Indictment Two of the 24 never faced trial. Robert Ley killed himself before proceedings began, and Gustav Krupp was ruled physically unfit. The remaining 22 were tried at the Palace of Justice in Nuremberg, chosen because it was largely undamaged and had an attached prison secure enough to hold them.
The prosecution built its case on the Nazis’ own paperwork. The regime had documented transports, killing operations, and policy decisions with bureaucratic precision, and prosecutors used that record to show the Holocaust as a coordinated state enterprise. After nearly a year of proceedings, the tribunal handed down twelve death sentences, three life sentences, four prison terms of ten to twenty years, and three acquittals. Ten of the condemned were hanged on October 16, 1946. Hermann Göring poisoned himself hours before his scheduled execution, and Martin Bormann had been sentenced in absentia.
Criminal Organizations
Under Article 9 of the Charter, the tribunal could also declare entire organizations criminal, and it did so for the SS, the Gestapo, the SD, and the Leadership Corps of the Nazi Party. Once an organization was declared criminal, membership itself became a basis for prosecution in national courts across occupied Germany.4The Avalon Project. Judgment – The Accused Organizations The SA, the Reich Cabinet, and the General Staff were acquitted for lack of evidence that ordinary members knew of or participated in criminal acts. The judgment also drew a line: people drafted into membership without knowledge of criminal purposes, and who had not personally participated in crimes, were excluded from liability.
The Twelve Subsequent Nuremberg Cases
After the main tribunal concluded, the United States conducted twelve additional trials at Nuremberg under Allied Control Council Law No. 10, presided over by American military judges.5Office of the Historian, U.S. Department of State. The Nuremberg Trial and the Tokyo War Crimes Trials (1945-1948) These cases moved past top leadership and into the professional classes and mid-level officials who kept the machinery of persecution running.
The Doctors’ Trial in 1946–47 prosecuted 23 physicians and administrators for organizing or performing medical experiments on concentration camp prisoners: freezing tests, high-altitude pressure tests, malaria infections, and forced sterilization, none with the subjects’ consent. The trial also produced the Nuremberg Code, a set of ethical principles for human experimentation still cited in medical ethics today.6United States Holocaust Memorial Museum. The Doctors Trial – The Medical Case of the Subsequent Nuremberg Proceedings
The Jurists’ Trial examined how German judges and prosecutors had used their offices to give racial persecution the appearance of lawful process. The tribunal singled out Judge Oswald Rothaug, who had sentenced a Jewish man to death for alleged “racial pollution,” as a knowing instrument of the persecution program.7United States Holocaust Memorial Museum. Background – Jurists Trial Verdict
The Einsatzgruppen Trial addressed the mobile killing units that followed the German army into Soviet territory and shot Jews, Communists, and other targeted populations behind the eastern front. Twenty-four defendants, most of them senior SS officers, stood trial. Fourteen received death sentences, though most were later commuted.8United States Holocaust Memorial Museum. Subsequent Nuremberg Proceedings, Case 9, The Einsatzgruppen Case
Three cases targeted German industrialists who had profited from forced labor and plunder. The IG Farben case in 1947–48 charged 24 directors of the chemical conglomerate with using slave labor from concentration camps and looting plants in occupied countries. Thirteen were convicted, with prison terms ranging from eighteen months to eight years.9United States Holocaust Memorial Museum. Subsequent Nuremberg Proceedings, Case 6, The IG Farben Case Parallel cases addressed the Krupp and Flick firms. Observers found the sentences light given the scale of suffering involved, and several convicted industrialists returned to prominent business roles after serving abbreviated terms.
Allied Zone Trials
The four occupying powers ran their own war crimes proceedings in their zones, producing thousands of cases. The British tried 44 defendants in the Bergen-Belsen trial in 1945, including former commandant Josef Kramer, head female guard Elisabeth Volkenrath, and camp physician Fritz Klein. Eleven were sentenced to death, fourteen were acquitted, and the rest received prison terms of one to fifteen years, most reduced on appeal.10Bergen-Belsen Memorial. Prosecution Poland’s Supreme National Tribunal operated from 1946 to 1948 and tried 49 defendants in seven cases. The most notable was Rudolf Höss, the commandant of Auschwitz, convicted and hanged at the camp itself in 1947. The French and Soviet zones held proceedings as well, though many Soviet-zone trials were closed to outside observers.
The Eichmann Trial in Jerusalem
In 1960, Israeli intelligence agents captured Adolf Eichmann in Argentina, where he had been living under a false identity. His trial the following year was Israel’s first major Holocaust prosecution and rested on the Nazis and Nazi Collaborators (Punishment) Law of 1950, which gave Israeli courts jurisdiction over crimes against the Jewish people committed during the Nazi era.11The Knesset. Nazis and Nazi Collaborators (Punishment) Law, 5710-1950
More than a hundred witnesses testified, and the trial became one of the first to be widely televised. That changed the public record. Nuremberg had leaned on documents; Jerusalem put survivor testimony at the center. Eichmann, who had coordinated the logistics of deportations to extermination camps, argued he had followed orders. The court rejected that defense, convicted him on multiple counts including crimes against the Jewish people and crimes against humanity, and sentenced him to death. He was hanged in 1962. It remains the only execution ever carried out under Israeli civilian law.
West German Domestic Trials
Once the occupation ended, prosecuting Nazi-era crimes became the German court system’s job, and progress was slow. German prosecutors had little appetite for the work in the 1950s, and public sentiment favored moving on. The turn came through Fritz Bauer, the attorney general of Hesse, who in 1959 received lists of Auschwitz guards from a journalist and immediately applied for jurisdiction to bring a case in Frankfurt.
The Frankfurt Auschwitz trials ran from 1963 to 1965 and were the first serious effort by a German court to prosecute camp personnel under domestic criminal law rather than an international charter. The legal terrain was harder. Section 211 of the German Criminal Code, the murder statute, required proof that each defendant had acted with personal cruelty or base motives.12Zentrale Stelle der Landesjustizverwaltungen. Criminal Acts Tying a specific guard to a specific killing, years later, when most witnesses had been murdered, was a far higher bar than the organizational liability applied at Nuremberg. Hundreds of witnesses testified. Several defendants received life sentences; others got shorter terms based on what could be proved about their individual conduct. Many perpetrators escaped conviction entirely because no surviving witness could tie them to a specific killing.
Recent Prosecutions of Elderly Guards
The Section 211 problem held for decades. It broke in 2011 with the conviction of John Demjanjuk, a former guard at the Sobibor killing center. A Munich court found him guilty as an accessory to the murder of over 28,000 people, based solely on his service at the camp, without evidence linking him to any individual death.13United States Holocaust Memorial Museum. John Demjanjuk – Prosecution of a Nazi Collaborator Functioning as a cog in the killing machinery, the court held, was enough for criminal liability.
That precedent opened a wave of late prosecutions. Oskar Gröning, an SS member who had sorted arriving prisoners’ belongings at Auschwitz and was nicknamed the “Bookkeeper of Auschwitz,” was convicted in 2015 as an accessory to the murder of 300,000 people and sentenced to four years. He never served the sentence because of appeals and died in 2018. Reinhold Hanning, a former Auschwitz guard, was convicted in 2016 as an accessory to at least 170,000 murders and sentenced to five years. He too died before entering prison.
Defendants in these cases are in their nineties, sometimes barely able to sit through proceedings, facing charges for acts committed when they were teenagers or young men. The sentences, even when imposed, are largely symbolic. German prosecutors maintain that the principle matters: under German law, murder has no statute of limitations, and participation in genocide carries lifelong exposure.12Zentrale Stelle der Landesjustizverwaltungen. Criminal Acts The window is closing. Within a few years, no living defendants will be left.
U.S. Denaturalization Cases
Hundreds of Nazi perpetrators entered the United States after the war, often by concealing wartime activities on immigration paperwork. The Constitution’s ban on retroactive criminal law blocked direct prosecution for those acts, so in 1979 the Department of Justice created the Office of Special Investigations to strip these individuals of citizenship and deport them through civil proceedings.14United States Holocaust Memorial Museum. Office of Special Investigations
The theory was that citizenship obtained through fraud could be revoked. The Supreme Court confirmed the approach in 1981 in Fedorenko v. United States, ruling that citizenship gained through willful concealment of material facts must be set aside, with no room for courts to weigh equitable factors like conduct since arriving in the country.15Justia. Fedorenko v. United States The defendant had concealed his service as an armed guard at the Treblinka killing center. Over three decades, OSI opened hundreds of investigations, secured the denaturalization or removal of more than 100 Nazi offenders, and blocked more than 200 suspected perpetrators from entering the country. In 2010, OSI merged into the Justice Department’s Human Rights and Special Prosecutions Section, whose mandate now covers post-WWII perpetrators of genocide, torture, and extrajudicial killing.
A Note on Reparations
Reparations and property restitution proceed on a separate civil and diplomatic track, not through the criminal trials. West Germany’s 1952 Luxembourg Agreement committed 3 billion Deutsche Marks to Israel and an additional 450 million to the Conference on Jewish Material Claims Against Germany, paid over fourteen years largely in goods.16United Nations Treaty Collection. Reparations Agreement between Israel and the Federal Republic of Germany In the United States, the Holocaust Expropriated Art Recovery (HEAR) Act of 2016 set a six-year federal statute of limitations for claims to recover stolen artwork, starting from the date a family discovers where the work is located, with a sunset clause set to expire in 2026.17Congresswoman Laurel Lee.

The Legal Legacy
The trials built an architecture of international criminal law that did not exist before 1945. The most immediate product was the rejection of the “superior orders” defense. Article 8 of the Nuremberg Charter stated that acting on orders from a government or superior does not free a person from responsibility, though it may be considered as mitigation at sentencing.2The Avalon Project. Charter of the International Military Tribunal
In 1950, the United Nations International Law Commission codified the tribunal’s core holdings into seven Nuremberg Principles: that any person who commits a crime under international law is personally responsible, that acting as a head of state gives no immunity, and that obeying superior orders is no defense where a moral choice was possible, among others.18United Nations International Law Commission. Principles of International Law Recognized in the Charter of the Nuremberg Tribunal Those principles became the foundation for every international criminal court that followed. The ad hoc tribunals for the former Yugoslavia and Rwanda in the 1990s drew directly on Nuremberg precedent, and the permanent International Criminal Court, established by the Rome Statute in 1998, has described itself as the “historical continuance” of the Nuremberg Tribunal.19International Criminal Court. Statement of ICC Judges on the Occasion of Their Judicial Retreat in Nuremberg The 1948 Genocide Convention, which defined genocide as an international crime and obligated signatory states to prevent and punish it, was shaped by the same body of thinking.
What the trials established seems obvious now but was radical when it was tested: the machinery of a state does not shield the people who operate it. A bureaucrat who processes deportation orders, a doctor who conducts lethal experiments, a judge who sentences people under racial laws, a guard at the gate of a death camp — each bears individual criminal responsibility. That principle, worked out first in Nuremberg and Jerusalem and Frankfurt, remains the bedrock of international criminal law.
