Hitler's vitriolic beer-hall speeches began attracting regular audiences. Early followers included army captain Ernst Rohm, the head of the Nazi paramilitary organization, the Sturmabteilung (SA), which protected meetings and frequently attacked political opponents.
On November 8, 1923, Hitler and the SA stormed a public meeting of 3,000 people at a large beer hall in Munich. Hitler announced that the national revolution had begun and declared the formation of a new government. After a short struggle including 20 deaths, the coup, known as the "Beer Hall Putsch," failed.
Hitler was arrested three days later and tried for high treason. He served a year in prison, during which time he dictated most of the first volume of Mein Kampf ("My Struggle") to his deputy, Rudolf Hess. The book laid out Hitler's plans for transforming German society into one based on race.
The Great Depression in Germany provided a political opportunity for Hitler. Germans were ambivalent to the parliamentary republic and increasingly open to extremist options. In 1932, Hitler ran against Paul von Hindenburg for the presidency. Hitler came in second in both rounds of the election, garnering more than 35 percent of the vote in the final election. The election established Hitler as a strong force in German politics. Hindenburg reluctantly agreed to appoint Hitler as chancellor in order to promote political balance.
