Former Nazi leader Adolf Eichmann was sentenced to death after being found guilty on fifteen criminal charges, including war crimes and crimes against humanity.

Otto Adolf Eichmann was a German-Austrian official of the Nazi Party, an officer of the Schutzstaffel (SS), and one of the major organisers of the Holocaust. He participated in the January 1942 Wannsee Conference, at which the implementation of the genocidal Final Solution to the Jewish Question was planned. Following this, he was tasked by SS-Obergruppenführer Reinhard Heydrich with facilitating and managing the logistics involved in the mass deportation of millions of Jews to Nazi ghettos and Nazi extermination camps across German-occupied Europe. He was captured and detained by the Allies in 1945, but escaped and eventually settled in Argentina. In May 1960, he was tracked down and apprehended by Israel's Mossad intelligence agency, and put on trial before the Supreme Court of Israel. The highly publicised Eichmann trial resulted in his conviction in Jerusalem, following which he was executed by hanging in 1962.

A war crime is a violation of the laws of war that gives rise to individual criminal responsibility for actions by combatants in action, such as intentionally killing civilians or intentionally killing prisoners of war, torture, taking hostages, unnecessarily destroying civilian property, deception by perfidy, wartime sexual violence, pillaging, and for any individual that is part of the command structure who orders any attempt to committing mass killings, the granting of no quarter despite surrender, the conscription of children in the military, and flouting the legal distinctions of proportionality and military necessity.

Crimes against humanity are certain serious crimes committed as part of a large-scale attack against civilians. Unlike war crimes, crimes against humanity can be committed during both peace and war and against a state's own nationals as well as foreign nationals. Together with war crimes, genocide, and the crime of aggression, crimes against humanity are one of the core crimes of international criminal law and, like other crimes against international law, have no temporal or jurisdictional limitations on prosecution.
