The Coup of 30 Prairial Year VII (Coup d'État du 30 prairial an VII), also known as the Revenge of the Councils (revanche des conseils) was a bloodless coup in France that occurred on 18 June 1799—30 Prairial Year VII by the French Republican Calendar. It left Emmanuel-Joseph Sieyès as the dominant figure of the French government, and prefigured the coup of 18 Brumaire that brought Napoleon Bonaparte to power.
