Adolf Hitler (1889-1945), chairman of the Nazi party, led an abortive attempt to overthrow the republican government of Germany. On November 8, 1923, his storm troopers invaded a large political meeting in a Munich beer hall and coerced Bavarian leaders into proclaiming loyalty to the Nazis. But the leaders escaped and quickly mobilized the German army against the coup. Upon realizing that he lacked the support of the army, Hitler fled but was soon arrested. During his nine months' imprisonment in the Landsberg fortress, he dictated Mein Kampf, which became the bible of National Socialism. The putsch, though a fiasco, brough Hitler to national prominence, making him a hero to many Germans.
