The rise to power of Adolf Hitler, dictator of Germany during the Nazi era from 1933 until his suicide in 1945, began in the newly established Weimar Republic in September 1919, when Hitler joined the Deutsche Arbeiterpartei (DAP; German Workers' Party). He quickly rose to a place of prominence and became one of its most popular speakers. In an attempt to more broadly appeal to larger segments of the population and win over German workers, the party name was changed to the Nationalsozialistische Deutsche Arbeiterpartei (NSDAP; National Socialist German Workers' Party), commonly known as the Nazi Party, and a new platform was adopted. Hitler was made the party leader in 1921 after he threatened to otherwise leave. By 1922, his control over the party was unchallenged. The Nazis were a right-wing party, but in the early years they also had anti-bourgeois elements. Hitler later initiated a purge of these elements and reaffirmed the Nazi Party's support for collaboration with German businesses. This included killings of Hitler's critics within the party during the Night of the Long Knives, which also served as a tool to secure power.
In 1923, Hitler attempted a coup in Bavaria, known as the Beer Hall Putsch. He was arrested and put on trial, which garnered him national fame. He was sentenced to five years in fortress confinement, but served only nine months. During this time, he wrote Mein Kampf, which became the handbook of his ideology of Nazism. Once released, Hitler switched tactics, opting to instead seize power through legal and democratic means. During the 1920s, he and the Nazis ran on a platform of anti-communism, antisemitism, and ultranationalism. Party leaders vociferously criticized the ruling democratic government and the Treaty of Versailles, while promising to turn Germany into a world power. Most Germans were indifferent to Hitler's rhetoric as the German economy began to recover, in large part due to loans from the United States under the Dawes Plan. The German political landscape was dramatically affected by the Wall Street crash of 1929. The Great Depression brought the German economy to a halt and further polarized German politics. During this tumultuous time, the German Communist Party also began campaigning and called for a revolution. Some business leaders, fearful of a communist takeover, began supporting the Nazi Party.
