The Beer Hall Putsch was a failed coup d'état in Munich, Germany between the evening of 8 November and the morning of 9 November 1923.
During the Putsch, the Nazi Party under Adolf Hitler tried to take over the government of Bavaria, a state in Germany. They took several hundred people hostage in a beer hall (a large building where people got together to drink beer and sometimes listen to political speeches).
Several Nazis died when they got into a gun fight with police officers in another part of Munich. Hitler went to prison for eight months and wrote his manifesto Mein Kampf during that time.
