The Holocaust, the systematic genocide of six million Jews and millions of others by Nazi Germany during World War II, involved key perpetrators at the highest levels of the Nazi regime. Adolf Hitler, as Führer, set the ideological foundation and authorized the "Final Solution." Heinrich Himmler, head of the SS, oversaw the implementation through concentration and extermination camps.

Nazi Leadership Core

Reinhard Heydrich, Himmler's deputy, chaired the 1942 Wannsee Conference that coordinated the mass murder and managed early extermination efforts in occupied Poland until his assassination. Adolf Eichmann organized the logistics of deporting Jews across Europe to death camps like Auschwitz. Other SS figures like Reinhard Heydrich and Josef Mengele (Auschwitz "Angel of Death") directly supervised killings and horrific experiments.

SS and Einsatzgruppen Roles

  • Heinrich Himmler directed the SS and Einsatzgruppen mobile killing squads, responsible for over a million shootings in Eastern Europe.
  • Paul Blobel led massacres like Babi Yar, where 33,000 Jews were murdered in two days.
  • Karl Jäger documented killing 137,000 in Lithuania via his report.
  • Friedrich Jeckeln ordered over 100,000 deaths in Ukraine and Ostland.

These units escalated from shootings to industrialized gassing after 1941.

Collaborators and Officials

Beyond Germans, local collaborators in occupied nations aided deportations. Vojtech Tuka, Slovak Prime Minister, facilitated sending 70,000 Jews to camps. Ferdinand von Sammern-Frankenegg oversaw Warsaw Ghetto liquidation, deporting 250,000+ to Treblinka. Allies like Hungary's under Ferenc Szálasi deported 400,000 Jews late in the war.

Broader Involvement

Ordinary Germans, police battalions, and Wehrmacht soldiers participated through complicity or direct action, as explored in USHMM resources on bystanders and collaborators. Companies like IG Farben supplied Zyklon B gas; railways enabled transports. Post-war trials like Nuremberg held thousands accountable, revealing widespread bureaucratic zeal.

This dark chapter, from 1941-1945, underscores how ideology, obedience, and hatred converged—no single person, but a machinery of evil.

TL;DR: Primarily Nazi leaders (Hitler, Himmler, Heydrich, Eichmann), SS units, and collaborators; millions enabled it through action or silence.
