If Heinrich Himmler had survived the final weeks of World War II and stood before the International Military Tribunal at Nuremberg, there is almost no doubt that he would have faced the death penalty. Himmler was not just another high-ranking official inside Nazi Germany. He was one of the most powerful men in the entire regime.
As the head of the SS, Himmler sat at the center of the Nazi system of repression. His position put him in control of concentration camps, deportations, forced labor, and mass murder. By 1945, he had accumulated extraordinary power across Germany and much of occupied Europe.
His official title was Reichsführer-SS, meaning he led the Schutzstaffel, known simply as the SS. What began as a relatively small organization eventually grew into a vast network controlling different parts of the Nazi state. In 1936, Himmler also became chief of the German police, effectively merging the SS and much of the German police system under his authority.
This meant Himmler was far more than a political figure. Under his command were organizations including the Gestapo, the Security Police, and the Security Service. The SS also controlled the concentration camp system. The Waffen-SS developed into a massive armed force that fought alongside the German army.
Most importantly, Heinrich Himmler became one of the most central figures in the Holocaust. He began the persecution of Jewish people long before the war, but German policy became far more deadly after the invasion of Poland in 1939. This was especially true after the invasion of the Soviet Union in June 1941.
Behind the advancing German armies came special killing units known as Einsatzgruppen. These units, supported by other security and police forces, carried out numerous mass shootings. Entire communities were sometimes taken from their homes, marched outside towns and cities, forced toward prepared pits, and killed. Hundreds of thousands of people were murdered this way during the early months of the invasion of the Soviet Union. Eventually, the number of victims of these mass shootings exceeded one million people.
Himmler could not realistically claim ignorance of these massacres. Reports documenting the activities of the Einsatzgruppen were prepared and distributed among senior officials. Himmler also visited the occupied Soviet territories himself. In August 1941, near Minsk, he personally witnessed a mass execution. His involvement went far beyond being a distant leader of an organization whose members committed atrocities.
The concentration camps would also have provided a massive amount of evidence in any case against him. The SS controlled the camps from the early years of Nazi rule. Dachau, opened in 1933, became an important model for the system. Over the following years, other camps were established, including Sachsenhausen, Buchenwald, Ravensbrück, and Neuengamme.
After the war began, the camp system expanded significantly throughout German-occupied Europe. Prisoners suffered starvation, disease, beatings, execution, and forced labor. Many were deliberately worked to death. Others were killed as part of organized killing programs. SS personnel eventually controlled Auschwitz, which became a combined concentration and extermination complex. Himmler visited Auschwitz and maintained close contact with senior SS officers involved in the camp system.
The extermination of Europe’s Jewish population would have been the most serious evidence presented against him. During the war, millions of men, women, and children were deported from Germany and occupied Europe. Many were transported to killing centers in occupied Poland. Camps such as Treblinka, Sobibor, and Bełżec were established primarily for mass murder, while Auschwitz-Birkenau became the largest killing center operated by Nazi Germany.
Himmler’s own words would have made it difficult for him to defend himself. His speeches in Poznań in October 1943 were among the most important evidence. Speaking to senior SS officers, Himmler openly discussed the extermination of Europe’s Jewish population. His language showed that he was fully aware of what was happening and considered it an achievement of his SS. For Allied prosecutors, this would have been extremely powerful evidence. Himmler could not claim the atrocities were committed secretly by subordinates without his knowledge.
Forced labor would have been another major charge. As Germany’s military situation deteriorated, the Nazi regime became increasingly dependent on millions of foreign workers and prisoners. People were taken from occupied territories and forced to work in factories, mines, construction projects, and armaments facilities. Concentration camp prisoners were supplied to German companies and military projects. Conditions in these camps were horrific. Prisoners were often denied adequate food, clothing, and medical care while being required to perform heavy physical labor.
Himmler was also involved in Nazi racial and population policies. He was appointed Reich Commissioner for the Strengthening of Germandom, giving him an important role in plans to reshape occupied territories according to Nazi racial ideas. People were expelled from their homes, populations were relocated, and children considered suitable for Germanization could be taken and integrated into German society. These policies particularly affected Poland and other regions in Eastern Europe.
If Himmler had appeared before the Nuremberg court, Allied prosecutors would have had an enormous amount of evidence available. They could have presented documents, reports, orders, letters, and testimony from survivors and captured German officials. His position would have made it extremely difficult for him to distance himself from what happened.
The fate of other senior SS officials offers some indication of what likely awaited him. Ernst Kaltenbrunner became head of the Reich Main Security Office in 1943. Despite attempting to deny responsibility for many crimes attributed to the security organizations, the Nuremberg court convicted him of war crimes and crimes against humanity. He was sentenced to death and executed by hanging in October 1946.
Himmler had far more influence. He led the SS for many years and ranked above Kaltenbrunner in the Nazi hierarchy. If Kaltenbrunner received the death penalty for his involvement in the SS security apparatus, it is very difficult to imagine Himmler receiving any lesser punishment. The SS itself was declared a criminal organization at Nuremberg.
Himmler’s defense would likely have tried to place ultimate blame on Hitler. He might have said he was only following Hitler’s orders. Many defendants at Nuremberg tried in various ways to distance themselves from the worst crimes of the regime. These arguments would not have succeeded. The Nuremberg court did not accept that simply following orders absolved personal responsibility for criminal acts. More importantly, Himmler was himself one of the people giving orders. He was not a minor officer facing orders from above. He was one of the most powerful decision-makers in Nazi Germany.
But Himmler never appeared in the Nuremberg courtroom. During Germany’s collapse in May 1945, he tried to disappear among the millions of soldiers and civilians moving across the country. He used forged identity papers and altered his appearance, but British forces eventually detained him. His true identity was discovered, and he died while in British custody on May 23, 1945. The main Nuremberg trial did not begin until November 1945.
As a result, one of the most important potential defendants was absent from the courtroom. If Himmler had lived to stand trial, he would certainly have been among the senior Nazi leaders prosecuted. He might have been considered alongside Hermann Göring as the most important defendant of all. The evidence against him would have covered every major category of Nazi wartime and criminal activity examined at Nuremberg: concentration camps, forced labor, deportations, persecution, mass killings, racial policies, and the systematic murder of millions.
The outcome of a trial that never happened can never be known with absolute certainty. But with Heinrich Himmler, the likely result is very clear. He spent years building and leading the SS, which committed enormous crimes across Europe. His own speeches proved his knowledge of mass murder. For all of this, Heinrich Himmler would certainly have been executed.
