Adolf Hitler is arrested in Munich for high treason for his role in the Beer Hall Putsch.

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.

Munich is the capital and most populous city of Bavaria, Germany. As of 30 November 2024, its population was 1,604,384, making it the third-largest city in Germany after Berlin and Hamburg. Munich is the largest city in Germany that is not a state of its own, and it ranks as the 11th-largest city in the European Union.

Treason is the crime of attacking a state authority to which one owes allegiance. This typically includes acts such as participating in a war against one's native country, attempting to overthrow its government, spying on its military, its diplomats, its officials, or its secret services for a hostile foreign power, or attempting to kill its head of state. A person who commits treason is known in law as a traitor.

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.
