Adolf Hitler is sentenced to five years fortress confinement for his participation in the "Beer Hall Putsch" but spends only nine months in jail.

Adolf Hitler was an Austrian-born German politician who was the dictator of Germany during the Nazi period from 1933 until his suicide in 1945. He rose to power as the leader of the Nazi Party, becoming the chancellor in 1933 and then taking the title of Führer und Reichskanzler in 1934. His invasion of Poland on 1 September 1939 marked the start of the Second World War. He was closely involved in military operations throughout the war and was central to the perpetration of the Holocaust: the genocide of about six million Jews and millions of other victims.

Festungshaft was a privileged custodial sentence in Germany from the 16th century until 1970. It also existed in some neighbouring territories and states.

The Beer Hall Putsch, also known as the Munich Putsch, was a failed coup d'état by Nazi Party leader Adolf Hitler, Erich Ludendorff and other Kampfbund leaders in Munich, Bavaria, on 8–9 November 1923, during the period of the Weimar Republic. Inspired by Mussolini's March on Rome, Hitler's goal was to use Munich as a base for a march against Germany's national government in Berlin.
