The Nazi Party's precursor, the Pan-German nationalist and antisemitic German Workers' Party, was founded on 5 January 1919. By the early 1920s the party was renamed the National Socialist German Workers' Party – to attract workers away from left-wing parties such as the Social Democrats (SPD) and the Communists (KPD) – and Adolf Hitler assumed control of the organization. The National Socialist Program or "25 Points" was adopted in 1920 and called for a united Greater Germany that would deny citizenship to Jews or those of Jewish descent, while also supporting land reform and the nationalization of some industries. In Mein Kampf ("My Struggle"; 1924–1925), Hitler outlined the anti-Semitism and anti-Communism at the heart of his political philosophy, as well as his disdain for representative democracy and his belief in Germany's right to territorial expansion.
Despite the spirit of freezing the site in time, some exhibits have been redesigned in recent years — the Russian Federation’s tells the story of Russian political prisoners here; those of the Netherlands and France and Belgium talk about the fate of their Jews; the exhibit dedicated to the Sinti and Roma present the often-neglected story of those peoples murdered here. The Polish exhibit is colored by the country’s Communist past.
Life for the eight people in the small apartment, which Anne Frank referred to as the Secret Annex, was tense. The group lived in constant fear of being discovered and could never go outside. They had to remain quiet during daytime in order to avoid detection by the people working in the warehouse below. Anne passed the time, in part, by chronicling her observations and feelings in a diary she had received for her 13th birthday, a month before her family went into hiding.
The first camp in Germany, Dachau, was founded in March 1933. The press announcement said that "the first concentration camp is to be opened in Dachau with an accommodation for 5,000 people. All Communists and – where necessary – Reichsbanner and Social Democratic functionaries who endanger state security are to be concentrated there, as in the long run it is not possible to keep individual functionaries in the state prisons without overburdening these prisons." Dachau was the first regular concentration camp established by the German coalition government of National Socialist Workers' Party (Nazi Party) and the Nationalist People's Party (dissolved on 6 July 1933). Heinrich Himmler, then Chief of Police of Munich, officially described the camp as "the first concentration camp for political prisoners."
