Pourquoi hitler est il emprisoné en 1923 ? Quel est le nom de son parti

C'était à cause d'un coup d'État raté.

Explanation:

Hitler was imprisoned due to a failed coup d'état on the Feldherrnhalle. Approximately two thousand Nazis marched on the Feldherrnhalle, in the city centre, but were confronted by a police cordon, and this resulted in sixteen deaths of Nazi Party members and four police officers. Wounded during the clash Hitler escaped immediate arrest and spirited off to safety in the countryside, though after two days, he and found and arrested. He was charged with treason and sentenced to five years in Landsberg Prison. He was released though after only serving nine months. When he was released, Hitler redirected his focus towards obtaining power through legal means rather than by revolution or force, and accordingly changed his tactics, further developing Nazi propaganda.

sitting in that one chair where he could get shot at was his worst decision.
