When the stock market in the United States crashed on 24 October 1929, the effect in Germany was dire. Millions were thrown out of work and several major banks collapsed. Hitler and the NSDAP prepared to take advantage of the emergency to gain support for their party. They promised to strengthen the economy and provide jobs. Many voters decided the NSDAP was capable of restoring order, quelling civil unrest, and improving Germany's international reputation. After the federal election of 1932, the NSDAP was the largest party in the Reichstag, holding 230 seats with 37.4 percent of the popular vote.
During the era of Imperial Germany, Völkisch nationalism was overshadowed by both Prussian patriotism and the federalist tradition of its various component states. The events of World War I, including the end of the Prussian monarchy in Germany, resulted in a surge of revolutionary Völkisch nationalism. The Nazis supported such revolutionary Völkisch nationalist policies and they claimed that their ideology was influenced by the leadership and policies of German Chancellor Otto von Bismarck, the founder of the German Empire. The Nazis declared that they were dedicated to continuing the process of creating a unified German nation state that Bismarck had begun and desired to achieve. While Hitler was supportive of Bismarck's creation of the German Empire, he was critical of Bismarck's moderate domestic policies. On the issue of Bismarck's support of a Kleindeutschland ("Lesser Germany", excluding Austria) versus the Pan-German Großdeutschland ("Greater Germany") which the Nazis advocated, Hitler stated that Bismarck's attainment of Kleindeutschland was the "highest achievement" Bismarck could have achieved "within the limits possible at that time". In Mein Kampf (My Struggle), Hitler presented himself as a "second Bismarck".
The Franks realized that conditions in Germany were only going to get worse and decided to leave the country. Otto traveled to Amsterdam, the Netherlands, that summer believing that his family would be safer there than in Germany. In September he established an independent branch of Opekta Werk, which made fruit pectin for jams and jellies, and a few years later, Pectacon, which made meat spices. When Otto left for Amsterdam, Edith and the girls went to stay with Grandmother Holländer, Edith’s mother, in Aachen, Germany. In December, Edith and Margot joined Otto in Amsterdam and Anne followed in February 1934. In March 1939, Grandmother Holländer joined them also.

In July 1942, when transports from the Westerbork transit camp to Auschwitz began, the family went into hiding together with the van Pels family and Fritz Pfeffer. The hiding place of these eight people was an attic at 263 Prisengracht Street in Amsterdam, the building that contained Otto’s business. For two years, from June 1942, when Anne received a diary for her thirteenth birthday, until she was about fifteen, Anne wrote in her diary nearly every day. Once the hiding place was discovered on August 4, 1944, the diary entries stopped.
The Republic of Czechoslovakia was home to a substantial minority of Germans, who lived mostly in the Sudetenland. Under pressure from separatist groups within the Sudeten German Party, the Czechoslovak government offered economic concessions to the region. Hitler decided to incorporate not just the Sudetenland but all of Czechoslovakia into the Reich. The Nazis undertook a propaganda campaign to try to generate support for an invasion. Top German military leaders opposed the plan, as Germany was not yet ready for war.
Between May 15 and July 9, 1944, some 438,000 Hungarian Jews were shipped on 147 trains to Birkenau, stretching the camp’s resources for killing beyond all limits. Because the crematoria were overcrowded, bodies were burned in pyres fueled partly by the victims’ own fat. Just prior to the deportation of Hungarian Jewry, two prisoners escaped with plans of the camp. They met with resistance leaders in Slovakia and compiled a detailed report including maps. As this report made its way to Western intelligence services in the summer of 1944, there were requests to bomb Auschwitz. Although the industrial complex adjacent to Auschwitz was bombed, the death camp and its crematoria were left untouched, a subject of controversy more than 50 years later. (See Why Wasn’t Auschwitz Bombed?)
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. 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, while the Jewish Virtual Library estimates that the number of Nazi camps was closer to 15,000 in all of occupied Europe and that many of these camps were run for a limited amount of time before they were closed. 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.
