German-occupied Europe in the context of "Adolf Hitler's directives"

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.

Antisemitism, the prejudice or discrimination against Jews, has had a long history since the ancient times. While antisemitism had already been prevalent in ancient Greece and the Roman Empire, its institutionalization in European Christianity after the destruction of the ancient Jewish cultural center in Jerusalem caused two millennia of segregation, expulsions, persecutions, pogroms, genocides of Jews, which culminated in the 20th-century Holocaust in Nazi German-occupied European states, where 67% of all European Jews were murdered.

The yellow badge, also known as the yellow patch, the Jewish badge, or the yellow star (German: Judenstern, lit. 'Jew's star'), was an accessory that Jews were required to wear in certain non-Jewish societies throughout history. A Jew's ethno-religious identity, which would be denoted by the badge, would help to mark them as an outsider. Legislation that mandated Jewish subjects to wear such items has been documented in some Middle Eastern caliphates and in some European kingdoms during the medieval period and the early modern period. The most recent usage of yellow badges was during World War II, when Jews living in Nazi Germany and German-occupied Europe were ordered to wear a yellow Star of David to keep their Jewish identity disclosed to the public in the years leading up to the Holocaust.

The Convention on the Prevention and Punishment of the Crime of Genocide (CPPCG), or the Genocide Convention, is an international treaty that criminalizes genocide and obligates state parties to pursue the enforcement of its prohibition. It was the first legal instrument to codify genocide as a crime and the first human rights treaty unanimously adopted by the United Nations General Assembly on 9 December 1948, during the third session of the United Nations General Assembly. The Convention entered into force on 12 January 1951 and has 153 state parties as of February 2025.

The Genocide Convention was conceived largely in response to World War II, which saw atrocities such as the Holocaust that lacked an adequate description or legal definition. Polish-Jewish lawyer Raphael Lemkin, who had coined the term genocide in 1944 to describe Nazi policies in occupied Europe and the Armenian genocide, campaigned for its recognition as a crime under international law. Lemkin also linked colonialism with genocide, mentioning colonial genocides outside of Europe in his writings. In a 1946 resolution, the General Assembly recognized genocide as an international crime and called for the creation of a binding treaty to prevent and punish its perpetration. Subsequent discussions and negotiations among UN member states resulted in the CPPCG.

Nazi Germany discriminated against and persecuted people on the basis of their race or ethnicity (actual or perceived), religious affiliation, political beliefs, sexual orientation, and, where applicable, mental or physical disabilities. Discrimination was institutionalized through legislation under the Nazi Party and perpetrated at an industrial scale, culminating in the Holocaust. Men, women, and children who were deemed mentally or physically unfit for society were subject to involuntary hospitalization, involuntary euthanasia, and forced sterilization.

The vast majority of the Nazi regime's victims were Jewish, Romani, or Slavic. Jews, along with some Romani populations, were deemed unfit for society on racial or ethnic grounds and largely confined to ghettos, then rounded up and deported to concentration or extermination camps. The beginning of World War II marked a colossal escalation in the Nazis' efforts to eliminate "inferior" communities across German-occupied Europe, with methods including: non-judicial incarceration, confiscation of property, forced labour (and extermination through hard labour), sexual slavery, human experimentation, malnourishment, and execution by death squads. For Jews, in particular, the Nazis' goal was total extermination—the genocide of the Jewish people, first in Europe and eventually in other parts of the world. This was presented by Adolf Hitler as the "Final Solution" to the Jewish question.

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.

Beginning with the invasion of Poland during World War II, the Nazi regime set up ghettos across German-occupied Eastern Europe in order to segregate and confine Jews, and sometimes Romani people, into small sections of towns and cities furthering their exploitation. In German documents, and signage at ghetto entrances, the Nazis usually referred to them as Jüdischer Wohnbezirk or Wohngebiet der Juden, both of which translate as the Jewish Quarter. There were several distinct types including open ghettos, closed ghettos, work, transit, and destruction ghettos, as defined by Holocaust historians. In a number of cases, they were the place of Jewish underground resistance against the German occupation, known collectively as the ghetto uprisings.

The Final Solution or the Final Solution to the Jewish Question was a plan orchestrated by Nazi Germany during World War II for the genocide of individuals they defined as Jews. The "Final Solution to the Jewish question" was the official code name for the murder of all Jews within reach, which was not restricted to the European continent. This policy of deliberate and systematic genocide starting across German-occupied Europe was formulated in procedural and geopolitical terms by Nazi leadership in January 1942 at the Wannsee Conference held near Berlin, and culminated in the Holocaust, which saw the murder of 90% of Polish Jews, and two-thirds of the Jewish population of Europe.

The nature and timing of the decisions that led to the Final Solution is an intensely researched and debated aspect of the Holocaust. The program evolved during the first 25 months of war leading to the attempt at "murdering every last Jew in the German grasp". Christopher Browning, a historian specializing in the Holocaust, wrote that most historians agree that the Final Solution cannot be attributed to a single decision made at one particular point in time. "It is generally accepted the decision-making process was prolonged and incremental." In 1940, following the Fall of France, Adolf Eichmann devised the Madagascar Plan to move Europe's Jewish population to the French colony, but the plan was abandoned for logistical reasons, mainly the Allied naval blockade. There were also preliminary plans to deport Jews to Palestine and Siberia. Raul Hilberg wrote that, in 1941, in the first phase of the mass-murder of Jews, the mobile killing units began to pursue their victims across occupied eastern territories; in the second phase, stretching across all of German-occupied Europe, the Jewish victims were sent on death trains to centralized extermination camps built for the purpose of systematic murder of Jews.

The use of slave and forced labour in Nazi Germany (German: Zwangsarbeit) and throughout German-occupied Europe during World War II took place on an unprecedented scale. It was a vital part of the German economic exploitation of conquered territories. It also contributed to the mass extermination of populations in occupied Europe. The Germans abducted approximately 12 million people from almost twenty European countries; about two thirds came from Central Europe and Eastern Europe.

Many workers died as a result of their living conditions – extreme mistreatment, severe malnutrition and abuse were the main causes of death. Many more became civilian casualties from enemy (Allied) bombing and shelling of their workplaces throughout the war. At the peak of the program, the forced labourers constituted 20% of the German work force. Counting deaths and turnover, about 15 million men and women were forced labourers at one point during the war. Besides Jews, the harshest deportation and forced labor policies were applied to the populations of Belarus, Ukraine, and Russia. By the end of the war, half of Belarus's population had been either killed or deported.
