Küstrin Putsch

The Küstrin Putsch of 1 October 1923, also known as the Buchrucker Putsch after its leader, was a coup attempt against the Weimar Republic by units of the paramilitary Black Reichswehr under Bruno Ernst Buchrucker. It was launched in response to nationalist anger over the government's decision to end passive resistance against the French and Belgian occupation of the Ruhr. It failed both in Berlin and in the eastern German town of Küstrin when the colonel in charge of the Küstrin Fortress detained Buchrucker and called in the Reichswehr. Buchrucker was convicted of treason and sentenced to prison but was amnestied after serving four years of the ten-year sentence.
