Collaboration with Nazi Germany and Fascist Italy in the context of "Holocaust denial"

The Holocaust (/ˈhɒləkɔːst/ HOL-ə-kawst), known in Hebrew as the Shoah (/ˈʃoʊə/ SHOH-ə; Hebrew: שּׁוֹאָה, romanized: Shoah, IPA: [ʃoˈʔa], lit. 'Catastrophe'), was the genocide of European Jews during World War II. From 1941 to 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe, around two-thirds of Europe's Jewish population. The murders were committed primarily through mass shootings across Eastern Europe and poison gas chambers in extermination camps, chiefly Auschwitz-Birkenau, Treblinka, Belzec, Sobibor, and Chełmno in occupied Poland. Separate Nazi persecutions killed millions of other non-Jewish civilians and prisoners of war (POWs); the term Holocaust is sometimes used to include the murder and persecution of non-Jewish groups.

The Nazis developed their ideology based on racism and pursuit of "living space", and seized power in early 1933. Meant to force all German Jews to emigrate, regardless of means, the regime passed anti-Jewish laws, encouraged harassment, and orchestrated a nationwide pogrom known as Kristallnacht in November 1938. After Germany's invasion of Poland in September 1939, occupation authorities began to establish ghettos to segregate Jews. Following the June 1941 invasion of the Soviet Union, 1.5 to 2 million Jews were shot by German forces and local collaborators. By early 1942, the Nazis decided to murder all Jews in Europe. Victims were deported to extermination camps where those who had survived the trip were killed with poisonous gas, while others were sent to forced labor camps where many died from starvation, abuse, exhaustion, or being used as test subjects in experiments. Property belonging to murdered Jews was redistributed to the German occupiers and other non-Jews. Although the majority of Holocaust victims died in 1942, the killing continued until the end of the war in 1945.

The French Resistance (French: La Résistance [la ʁezistɑ̃s]) was a collection of groups that fought the Nazi occupation and the collaborationist Vichy regime in France during the Second World War. Resistance cells were small groups of armed men and women (called the Maquis in rural areas) who conducted guerrilla warfare and published underground newspapers. They also provided first-hand intelligence information, and escape networks that helped Allied soldiers and airmen trapped behind Axis lines. The Resistance's men and women came from many parts of French society, including émigrés, academics, students, aristocrats, conservative Roman Catholics (including clergy), Protestants, Jews, Muslims, liberals, anarchists, communists, and some fascists. The proportion of the French people who participated in organized resistance has been estimated at from one to three percent of the total population.

The French Resistance played a significant role in facilitating the Allies' rapid advance through France following the invasion of Normandy on 6 June 1944. Members provided military intelligence on German defences known as the Atlantic Wall, and on Wehrmacht deployments and orders of battle for the Allies' invasion of Provence on 15 August. The Resistance also planned, coordinated, and executed sabotage acts on electrical power grids, transport facilities, and telecommunications networks. The Resistance's work was politically and morally important to France during and after the German occupation. The actions of the Resistance contrasted with the collaborationism of the Vichy régime.

Crimes against humanity are certain 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 (where universal jurisdiction is recognized).

The first prosecution for crimes against humanity took place during the Nuremberg trials and Subsequent Nuremberg trials against defeated leaders of Nazi Germany and collaborators. Crimes against humanity have been prosecuted by other international courts (such as the International Criminal Tribunal for the former Yugoslavia, the International Criminal Tribunal for Rwanda, the Special Court for Sierra Leone, the Extraordinary Chambers in the Courts of Cambodia, and the International Criminal Court) as well as by domestic courts. The law of crimes against humanity has primarily been developed as a result of the evolution of customary international law. Crimes against humanity are not codified in an international convention, so an international effort to establish such a treaty, led by the Crimes Against Humanity Initiative, has been underway since 2008.

Henri Philippe Bénoni Omer Joseph Pétain (French: [filip petɛ̃]; 24 April 1856 – 23 July 1951), better known as Marshal Pétain (French: maréchal Pétain, [maʁeʃal petɛ̃]), was a French military officer who commanded the French Army in World War I and later became the head of the collaborationist regime of Vichy France, from 1940 to 1944, during World War II.

Pétain was admitted to the Saint-Cyr Military Academy in 1876 and pursued a career in the military, achieving the rank of colonel by the outbreak of World War I. He led the French Army to victory at the nine-month-long Battle of Verdun, for which he was called "the Lion of Verdun" (French: le lion de Verdun). After the failed Nivelle Offensive and subsequent mutinies, he was appointed Commander-in-Chief and succeeded in restoring control. Pétain remained in command for the rest of the war and emerged as a national hero. During the interwar period, he was head of the peacetime French Army, commanded joint Franco-Spanish operations during the Rif War and served twice as a government minister. During this time he was known as le vieux Maréchal ("the Old Marshal").

Vichy France (French: Régime de Vichy, lit. 'Vichy regime'; 10 July 1940 – 9 August 1944), officially the French State (État français), was a French rump state headed by Marshal Philippe Pétain during World War II, established as a result of Germany victory in the Battle of France. It was named after its seat of government, the city of Vichy.

Officially independent, but with half of its territory occupied under the harsh terms of the 1940 armistice with Nazi Germany, it adopted a policy of collaboration. Though Paris was nominally its capital, the government established itself in Vichy in the unoccupied "free zone" (zone libre). The occupation of France by Germany at first affected only the northern and western portions of the country. In November 1942, the Allies occupied French North Africa, and in response the Germans and Italians occupied the entirety of Metropolitan France, ending any pretence of independence by the Vichy government.

Between 1933 and 1945, a large number of Jews emigrated from Nazi Germany and German-occupied Europe. This exodus was triggered by the militaristic antisemitism perpetrated by the Nazi Party and by Germany's collaborators, ultimately culminating in the Holocaust. However, even before the genocide itself, which began during World War II, the Nazis had widely sponsored or enforced discriminatory practices—by legislation, in many cases—against Jewish residents, such as through the Nazi boycott of Jewish-owned businesses. Although Adolf Hitler and the German government were initially accepting of voluntary Jewish emigration from the country, it became difficult to find new host countries, particularly as the 1930s were marked by the Great Depression, as the number of Jewish migrants increased. Eventually, the Nazis forbade emigration; the Jews who remained in Germany or in German-occupied territory by this point were either murdered in the ghettos or relocated to be systematically exploited and murdered at dedicated concentration camps and extermination camps throughout the European continent.

Paris-soir (French pronunciation: [paʁi swaʁ]) was a French newspaper founded in 1923 and published until 1944 when it was banned for having been a collaborationist newspaper during the war.

The Reichskommissariat Ostland (RKO; lit. 'Reich Commissariat of Eastland') was an administrative entity of the Reich Ministry for the Occupied Eastern Territories of Nazi Germany from 1941 to 1945. It served as the German civilian occupation regime in Lithuania, Latvia, Estonia, and the western part of the Byelorussian SSR during the Eastern Front of World War II.

Ostland was established after the success of the Wehrmacht's Baltic operation and an initial period of military administration by Army Group North Rear Area based on the equivalent Reichskommissariat Baltenland in German planning documents. It was divided into Generalbezirk Estland (Estonia), Generalbezirk Lettland (Latvia), Generalbezirk Litauen (Lithuania), and Generalbezirk Weißruthenien (Belarus) each with its own Nazi collaborationist government and Auxiliary Police under the control of a German Generalkommissar. Hinrich Lohse served as the Reichskommissar from 1941 to 1944 and Erich Koch from 1944 to 1945.

The Government of Vichy France was the collaborationist ruling regime or government in Nazi-occupied France during the Second World War. Of contested legitimacy, it was finally headquartered in the town of Vichy in occupied France, but it initially took shape in Bordeaux under Marshal Philippe Pétain as the successor to the French Third Republic in June 1940. The government remained in Vichy for four years, but was escorted to Germany in September 1944 after the Allied invasion of France. It then operated as a government-in-exile until April 1945, when the Sigmaringen enclave was taken by so-called Free French forces. Pétain was permitted to travel back to France (through Switzerland), by then under control of the technically illegal Provisional French Republic, and subsequently put on trial for treason.
