Germany's war in the East was based on Hitler's long-standing view that Jews were the great enemy of the German people and that Lebensraum was needed for Germany's expansion. Hitler focused his attention on Eastern Europe, aiming to conquer Poland and the Soviet Union.[182][183] After the occupation of Poland in 1939, all Jews living in the General Government were confined to ghettos, and those who were physically fit were required to perform compulsory labour.[317] In 1941 Hitler decided to destroy the Polish nation completely; within 15 to 20 years the General Government was to be cleared of ethnic Poles and resettled by German colonists.[318] About 3.8 to 4 million Poles would remain as slaves,[319] part of a slave labour force of 14 million the Nazis intended to create using citizens of conquered nations.[183][320]

One could call this a simple mistake, except that it echoed a similar incident the previous year, when visitors noticed a discrepancy in the museum’s audioguide displays. Each audioguide language was represented by a national flag—with the exception of Hebrew, which was represented only by the language’s name in its alphabet. The display was eventually corrected to include the Israeli flag.
The Nazis contested elections to the national parliament (the Reichstag) and to the state legislature (the Landtage) from 1924, although at first with little success. The "National-Socialist Freedom Movement" polled 3% of the vote in the December 1924 Reichstag elections and this fell to 2.6% in 1928. State elections produced similar results. Despite these poor results and despite Germany's relative political stability and prosperity during the later 1920s, the Nazi Party continued to grow. This was partly because Hitler, who had no administrative ability, left the party organisation to the head of the secretariat, Philipp Bouhler, the party treasurer Franz Xaver Schwarz and business manager Max Amann. The party had a capable propaganda head in Gregor Strasser, who was promoted to national organizational leader in January 1928. These men gave the party efficient recruitment and organizational structures. The party also owed its growth to the gradual fading away of competitor nationalist groups, such as the German National People's Party (DNVP). As Hitler became the recognised head of the German nationalists, other groups declined or were absorbed.

The soldiers also found warehouses containing 836,525 items of women clothing, 348,820 items of men clothing, 43,525 pairs of shoes and vast numbers of toothbrushes, glasses and other personal effects. They found also 460 artificial limbs and seven tons of human hair shaved from Jews before they were murdered. The human hairs were used by the company “Alex Zink” (located in Bavaria) for confection of cloth. This company was paying the Nazi’s 50 pfennig per kilo of human hair.
The publication of the English-language critical/definitive edition in 1989 sparked a worldwide wave of research that focused on Anne Frank from different perspectives: the literary perspective; the diary as a historical document; the feminist angle; the diary’s Jewish aspect and its portrayal of Jewish life in central and western Europe; wartime adolescence; the adolescence of a promising writer, and more. In 1996, Jon Blair’s documentary Anne Frank Remembered won an Academy Award, and another exhibit, Anne Frank: A History for Today, prepared at the Anne Frank House went on tour. The exhibit immediately became a symbol of struggle, deprivation and suffering, discrimination against the individual and minorities, occupation and oppression. In every place it was shown, the need to educate against fascism and xenophobia, Holocaust denial and antisemitism was emphasized. The catalog stresses that “[T]he Anne Frank House tries to realize Anne’s ideals as she spoke of them in her diary by fighting prejudice, antisemitism and racism through fostering pluralistic and democratic society. The guiding principle of the House’s work is the Universal Declaration of Human Rights.” Eleanor Roosevelt, who as a member of the United States’s delegation to the United Nations had headed the committee that prepared the Declaration in the wake of World War II, wrote the foreword to the diary’s English edition shortly afterward.

In 1940, the Nazis used carbon monoxide gas in secret euthanasia programs at mental hospitals in Germany to eliminate mentally ill or disabled people. From there, it was but a small step to Zyklon B, a cyanide compound designed for delousing. In September 1941, Auschwitz guards herded hundreds of Soviet POWs and sick inmates into the crudely sealed basement of Block 11, the dreaded punishment barrack; a guard threw in pellets of Zyklon B and shut the doors. They were the first people gassed at Auschwitz.
In January 1923, France occupied the Ruhr industrial region as a result of Germany's failure to meet its reparations payments. This led to economic chaos, the resignation of Wilhelm Cuno's government and an attempt by the German Communist Party (KPD) to stage a revolution. The reaction to these events was an upsurge of nationalist sentiment. Nazi Party membership grew sharply to about 20,000.[65] By November, Hitler had decided that the time was right for an attempt to seize power in Munich, in the hope that the Reichswehr (the post-war German military) would mutiny against the Berlin government and join his revolt. In this, he was influenced by former General Erich Ludendorff, who had become a supporter—though not a member—of the Nazis.
During the Battle of Berlin (16 April 1945 – 2 May 1945), Hitler and his staff lived in the underground Führerbunker while the Red Army approached.[139] On 30 April, when Soviet troops were within two blocks of the Reich Chancellery, Hitler, along with his girlfriend and by then wife Eva Braun committed suicide.[140] On 2 May, General Helmuth Weidling unconditionally surrendered Berlin to Soviet General Vasily Chuikov.[141] Hitler was succeeded by Grand Admiral Karl Dönitz as Reich President and Goebbels as Reich Chancellor.[142] Goebbels and his wife Magda committed suicide the next day after murdering their six children.[143] Between 4 and 8 May 1945, most of the remaining German armed forces unconditionally surrendered. The German Instrument of Surrender was signed 8 May, marking the end of the Nazi regime and the end of World War II in Europe.[144]
After September 1939, with the beginning of the Second World War, concentration camps became places where millions of ordinary people were enslaved as part of the war effort, often starved, tortured and killed.[21] During the war, new Nazi concentration camps for "undesirables" spread throughout the continent. According to statistics by the German Ministry of Justice, about 1,200 camps and subcamps were run in countries occupied by Nazi Germany,[22] while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe[23][24] and that many of these camps were run for a limited amount of time before they were closed.[23] Camps were being created near the centers of dense populations, often focusing on areas with large communities of Jews, Polish intelligentsia, Communists or Romani. Since millions of Jews lived in pre-war Poland, most camps were located in the area of the General Government in occupied Poland, for logistical reasons. The location also allowed the Nazis to quickly remove the German Jews from within Germany proper.
