France had approximately 300,000 Jews, divided between the German-occupied north and the unoccupied collaborationist southern areas under the Vichy regime. The occupied regions were under the control of a military governor, and there, anti-Jewish measures were not enacted as quickly as they were in the Vichy-controlled areas.[163] In July 1940, the Jews in the parts of Alsace-Lorraine that had been annexed to Germany were expelled into Vichy France.[164] Vichy France's government implemented anti-Jewish measures in French Algeria and the two French Protectorates of Tunisia and Morocco.[165] Tunisia had 85,000 Jews when the Germans and Italians arrived in November 1942. An estimated 5,000 Jews were subjected to forced labor.[166]
The Nazis regarded the Slavs as subhuman, or Untermenschen.[426] In a secret memorandum dated 25 May 1940, Himmler stated that it was in German interests to foster divisions between the ethnic groups in the East. He wanted to restrict non-Germans in the conquered territories to schools that would only teach them how to write their own name, count up to 500, and obey Germans.[427][y] In November 1939 German planners called for "the complete destruction" of all Poles[430] and resettlement of the land by German colonists.[431] The Polish political leadership was the target of a campaign of murder (Intelligenzaktion and AB-Aktion).[432] Between 1.8 and 1.9 million non-Jewish Polish citizens perished at German hands during the course of the war; about four-fifths were ethnic Poles and the rest Ukrainians and Belarusians.[410] At least 200,000 died in concentration camps, around 146,000 in Auschwitz. Others died in massacres or in uprisings such as the Warsaw Uprising, where 120,000–200,000 were killed.[433] During the occupation, the Germans adopted a policy of restricting food and medical services, as well as degrading sanitation and public hygiene.[434] The death rate rose from 13 per 1000 before the war to 18 per 1000 during the war.[435] Around 6 million of World War II victims were Polish citizens; half the death toll were Jews.[436] Over the course of the war Poland lost 20 percent of its pre-war population.[436] Over 90 percent of the death toll came through non-military losses, through various deliberate actions by Germany and the Soviet Union.[433] Polish children were also kidnapped by Germans to be "Germanized", with perhaps as many as 200,000 children stolen from their families.[437]

German-occupied Denmark rescued most of its own Jews by spiriting them to Sweden by sea in October 1943. This was possible partly because the German presence in Denmark was relatively small. Moreover, while anti-Semitism in the general population of many other countries led to collaboration with the Germans, Jews were an integrated part of Danish culture. Under these unique circumstances, Danish humanitarianism flourished.

As a temporary measure, while the top leadership considered long-term options, German authorities established ghettos in the Generalgouvernement (that part of German-occupied Poland not directly annexed to Germany, attached to German East Prussia or incorporated into the German-occupied Soviet Union) and in the District Wartheland, commonly called the Warthegau (an area of western Poland directly annexed to the German Reich). From late 1939, German SS and police authorities deported Polish, German, Austrian, and Czech Jews to these ghettos.

Chiune Sugihara (1 January 1900 – 31 July 1986) was a Japanese diplomat, serving as Vice Consul for the Japanese Empire in Lithuania. During World War II, he helped several thousand Jews leave the country by issuing transit visas to Jewish refugees so that they could travel to Japan. Most of the Jews who escaped were refugees from German-occupied Poland or residents of Lithuania. Sugihara wrote travel visas that facilitated the escape of more than 6,000 Jewish refugees to Japanese territory, risking his career and his family's life.

On April 17, 1944, Anne began writing in what turned out to be her final diary notebook. On the first page she wrote about herself: "The owner's maxim: Zest is what man needs!" A few months later, she and the other inhabitants of the annex celebrated the Allied invasion of France, which took place on June 6, 1944. They were certain the war would soon be over.
At the same time, the Germans set about liquidating the ghettos in occupied Poland. July 22, 1942, when the deportation of Jews from Warsaw to the death camp in Treblinka began, is regarded as a symbolic date. A decided majority of the Polish Jews were killed in a little over half a year, after which the SS began liquidating the Aktion Reinhard camps. However, the last great death camp—Auschwitz—remained in existence until the beginning of 1945. It was mainly Jews from Western and Southern Europe, from the liquidated labor camps, and the ghettos in Sosnowiec and Łódź, who died in the gas chambers there.
The ideology of Nazism brought together elements of antisemitism, racial hygiene, and eugenics, and combined them with pan-Germanism and territorial expansionism with the goal of obtaining more Lebensraum (living space) for the Germanic people.[16] Nazi Germany attempted to obtain this new territory by attacking Poland and the Soviet Union, intending to deport or kill the Jews and Slavs living there, who were considered by the Nazis to be inferior to the Aryan master race.[17]
