Gustav Ritter von Kahr (born the November 29th 1862 with Weißenburg in Bavaria and deceased the June 30th 1934 with Dachau) was a German Politician , president of the Bavaria of the March 16th 1920 with the September 11th 1921.

Gustav von Kahr made studies in right and became an eminent lawyer. Its sympathies of right-hand side push it to form in a brewery of Munich a “faction”. At the time when Adolf Hitler emerges in policy, he is elected president of the Bavaria. At the time, there was ten factions of right-hand side in Germany, but two more popular were those of the clan von Kahr and that of NSDAP directed by Adolf Hitler.

One day, the main leaders of the factions of right-hand side met to take part in a putsch, but one hid in Hitler the date planned for the Coup d'etat. The future Führer was furious to hear mouth of his/her collaborator Ernst Röhm whom it had been rejected by the other chiefs.

The November 8th 1923, at a meeting of the clan von Kahr, Adolf Hitler, Ernst Röhm, Hermann Göring and Rudolf Hess make irruption in the brewery Bürgerbräukeller with a hundred SA. They take as an hostage the chiefs of right-hand side and oblige them, with the point of rifle, to accept that Adolf Hitler is indicated chief of the armies at the time of the coup d'etat. Gustave Von Kahr, most influential, accepts. But when Hitler goes on Munich at the time of this “Putsch of the brewery”, von Kahr prevents the army that Hitler and its SA wants to seize the power. Result: imprisonment of Hitler and its partisans.

With the Nazi chief in prison, the disciples of Hitler court von Kahr. Not wanting to rub with their policy anti-semite, he resigned in 1924. Gustav von Kahr was stopped at the time of the Nuit of the Long Knives the June 30th 1934 and was assassinated.
