The minister-president of Austria was the head of government of the Austrian Empire from 1848, when the office was created in the course of the March Revolution. Previously, executive power rested with an Austrian State Council, headed by the emperor himself, from 1821 under the chairmanship of State Chancellor Prince Klemens von Metternich. The office of minister-president was not refilled from 1852, when Emperor Franz Joseph resumed control of the government affairs, and was replaced by a coordinating chairman of the Austrian Minister's Conference.
