Background: Adolf Hitler (German: ['adolf 'hItla] ( listen); 20 April 1889 - 30 April 1945) was a German politician who was the leader of the Nazi Party (Nationalsozialistische Deutsche Arbeiterpartei; NSDAP), Chancellor of Germany from 1933 to 1945 and Fuhrer ("Leader") of Nazi Germany from 1934 to 1945. As dictator, Hitler initiated World War II in Europe with the invasion of Poland in September 1939, and was central to the Holocaust. Hitler was born in Austria--then part of Austria-Hungary--and was raised near Linz. He moved to Germany in 1913 and was decorated during his service in the German Army in World War I.
Context: In 1923 Hitler enlisted the help of World War I General Erich Ludendorff for an attempted coup known as the "Beer Hall Putsch". The NSDAP used Italian Fascism as a model for their appearance and policies. Hitler wanted to emulate Benito Mussolini's "March on Rome" of 1922 by staging his own coup in Bavaria, to be followed by a challenge to the government in Berlin. Hitler and Ludendorff sought the support of Staatskommissar (state commissioner) Gustav Ritter von Kahr, Bavaria's de facto ruler. However, Kahr, along with Police Chief Hans Ritter von Seisser and Reichswehr General Otto von Lossow, wanted to install a nationalist dictatorship without Hitler.  On 8 November 1923 Hitler and the SA stormed a public meeting of 3,000 people organised by Kahr in the Burgerbraukeller, a beer hall in Munich. Interrupting Kahr's speech, he announced that the national revolution had begun and declared the formation of a new government with Ludendorff. Retiring to a back room, Hitler, with handgun drawn, demanded and got the support of Kahr, Seisser, and Lossow. Hitler's forces initially succeeded in occupying the local Reichswehr and police headquarters, but Kahr and his cohorts quickly withdrew their support. Neither the army, nor the state police, joined forces with Hitler. The next day, Hitler and his followers marched from the beer hall to the Bavarian War Ministry to overthrow the Bavarian government, but police dispersed them. Sixteen NSDAP members and four police officers were killed in the failed coup.  Hitler fled to the home of Ernst Hanfstaengl and by some accounts contemplated suicide. He was depressed but calm when arrested on 11 November 1923 for high treason. His trial before the special People's Court in Munich began in February 1924, and Alfred Rosenberg became temporary leader of the NSDAP. On 1 April, Hitler was sentenced to five years' imprisonment at Landsberg Prison. There, he received friendly treatment from the guards, and was allowed mail from supporters and regular visits by party comrades. Pardoned by the Bavarian Supreme Court, he was released from jail on 20 December 1924, against the state prosecutor's objections. Including time on remand, Hitler served just over one year in prison.  While at Landsberg, Hitler dictated most of the first volume of Mein Kampf (My Struggle; originally entitled Four and a Half Years of Struggle against Lies, Stupidity, and Cowardice) to his deputy, Rudolf Hess. The book, dedicated to Thule Society member Dietrich Eckart, was an autobiography and exposition of his ideology. The book laid out Hitler's plans for transforming German society into one based on race. Some passages imply genocide. Published in two volumes in 1925 and 1926, it sold 228,000 copies between 1925 and 1932. One million copies were sold in 1933, Hitler's first year in office.  Shortly before Hitler was eligible for parole, the Bavarian government attempted to have him deported back to Austria. The Austrian federal chancellor rejected the request on the specious grounds that his service in the German Army made his Austrian citizenship void. In response, Hitler formally renounced his Austrian citizenship on 7 April 1925.
