For two years, they lived in a secret attic apartment behind the office of the family-owned business at 263 Prinsengracht Street, which Anne referred to in her diary as the Secret Annex. Otto Frank’s friends and colleagues, Johannes Kleiman, Victor Kugler, Jan Gies and Miep Gies, had previously helped to prepare the hiding place and smuggled food and clothing to the Franks at great risk to their own lives.
The existing legal system provides appropriate tools for the effective protection and management of the property. The Museum Council, whose members are appointed by the Minister of Culture and National Heritage, supervises the performance of the Museum’s duties regarding its collections, in particular the execution of its statutory tasks. In addition, the International Auschwitz Council acts as a consultative and advisory body to the Prime Minister of the Republic of Poland on the protection and management of the site of the former Auschwitz Birkenau camp and other places of extermination and former concentration camps situated within the present territory of Poland.
As the German leader (Führer) of Nazi Germany, Hitler began moving Nazi armies into neighboring countries. When Germany attacked Poland, World War II started. Western countries like France, Belgium, and the Netherlands were occupied and to be treated by Germany as colonies. However, in Eastern countries, such as Poland and the Soviet Union, the Nazis planned to kill or enslave the Slavic peoples, so that German settlers could take their land.
A week after they had gone into hiding, the Franks were joined by Otto’s business associate Hermann van Pels (1898-1944), along with his wife Auguste (1900-45) and their son Peter (1926-45), who were also Jewish. A small group of Otto Frank’s employees, including his Austrian-born secretary, Miep Gies (1909-2010), risked their own lives to smuggle food, supplies and news of the outside world into the secret apartment, whose entrance was situated behind a movable bookcase. In November 1942, the Franks and Van Pels were joined by Fritz Pfeffer (1889-1944), Miep Gies’ Jewish dentist.
After the failure of the Beer Hall Putsch in 1923, and his subsequent trial and imprisonment, Hitler decided that the way for the Nazi Party to achieve power was not through insurrection, but through legal and quasi-legal means. This did not sit well with the brown-shirted stormtroopers of the SA, especially those in Berlin, who chafed under the restrictions that Hitler placed on them, and their subordination to the party. This resulted in the Stennes Revolt of 1930-31, after which Hitler made himself the Supreme Commander of the SA, and brought Ernst Röhm back to be their Chief of Staff and keep them in line. The quashing of the SA's revolutionary fervor convinced many businessmen and military leaders that the Nazis had put aside their insurrectionist past, and that Hitler could be a reliable partner 
On 15 September 1935, the Reichstag passed the Nuremberg Laws, prohibiting marriages between Jews and people of Germanic extraction, extramarital relations between Jews and Germans, and the employment of German women under the age of 45 as domestic servants in Jewish households. The Reich Citizenship Law defined as citizens those of "German or kindred blood". Thus Jews and other minorities were stripped of their citizenship. By the start of World War II in 1939, around 250,000 of Germany's 437,000 Jews had emigrated to the United States, Palestine, the United Kingdom, and other countries.
The Frank sisters were excelling in their studies and had many friends, but with the introduction of a decree that Jews could attend only Jewish schools, they were enrolled at the Jewish Lyceum. Anne became a friend of Jacqueline van Maarsen in the Lyceum. In April 1941, Otto took action to prevent Pectacon from being confiscated as a Jewish-owned business. He transferred his shares in Pectacon to Johannes Kleiman and resigned as director. The company was liquidated and all assets transferred to Gies and Company, headed by Jan Gies. In December, Otto followed a similar process to save Opekta. The businesses continued with little obvious change and their survival allowed Otto to earn a minimal income, but sufficient to provide for his family.
There are many self-reflective passages where Anne laments being picked on by the adults in the annex, wondering if she will live up to the expectations they have for her, hoping she can reach her goals. There is a thread of hope apparent even in her most depressing writings. I think these are the parts I think teens find most relate-able because all teens want to achieve things, please their parents, and find hope in their moments of despair.
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.
