Gave the president power to rule by decree without the consent of the Reichstag.
Ebert used article 48 during the crisis of 1919-24. He used it on 136 occasions.
He defeated threats to the Weimar Republic from the left, such as the Ruhr uprising of March 1920, and protected Weimar democracy during the first highly unstable few years.
He used it in a way that would have a destabilising effect in the late 1920s and early 1930s.
He used it to fight threats from the left; he did not tend to use emergency powers against the right.
He used it on occasion where there was no emergency, in order to bypass opposition in the Reichstag.
He established the precedent that the president could use Article 48 outside of emergencies and that the government viewed the left as a greater threat than the right.
