military personnel in exchange for giving Russia military technology. This was against the Treaty of Versailles, which limited Germany to 100,000 soldiers and no conscription, naval forces of 15,000 men, twelve destroyers, six battleships, and six cruisers, no submarines or aircraft. However, Russia had pulled out of the First World War against the Germans as a result of the 1917 Russian Revolution and was excluded from the League of Nations. Thus, Germany seized the chance to make an ally. Walther Rathenau, the Jewish Foreign Minister who signed the treaty, was assassinated two months later by two ultra-nationalist army officers. Further pressure from the political right came in 1923 with the Beer Hall Putsch (aka Munich Putsch), a failed power seizure staged by the Nazi Party under Adolf Hitler in Munich. In 1920, the German Workers' Party had become the National Socialist German Workers' Party (NSDAP), or Nazi Party, which would eventually become a driving force in the collapse of Weimar. Hitler named himself as chairman of the party in July 1921. On 8 November 1923, the Kampfbund, in a pact with Erich Ludendorff, took over a meeting by Bavarian prime minister Gustav von Kahr at a beer hall in Munich. Ludendorff and Hitler declared that the Weimar government was deposed and that they were planning to take control of Munich the following day. But the 3,000 rebels were no match yet for the Bavarian authorities. Hitler was arrested and sentenced to five years in prison for high treason, the minimum sentence for the charge. However, Hitler served less than eight months, in a comfortable cell, receiving a daily stream of visitors, until his release on 20 December 1924. While in jail, Hitler dictated Mein Kampf, which laid out his ideas and future policies. Hitler now decided to focus on legal methods of gaining power. Golden Era (1924–1929) Gustav Stresemann was Reichskanzler for 100 days in 1923, and served as foreign minister from 1923 to 1929, a period of relative stability for the Weimar Republic, known in Germany as Goldene Zwanziger ("Golden Twenties"). Prominent features of this period were a growing economy and a consequent decrease in civil unrest. Once civil stability had been restored, Stresemann began stabilising the German currency, which promoted confidence in the German economy and helped the recovery that was so greatly needed for the German nation to keep up with their reparation repayments, while at the
