When was the National Convention established in France?
National Convention
The National Convention (French: Convention nationale) was the first government of the French Revolution, following the two-year National Constituent Assembly and the one-year Legislative Assembly. Created after the great insurrection of 10 August 1792, it was the first French government organized as a republic, abandoning the monarchy altogether. The Convention sat as a single-chamber assembly from 20 September 1792 to 26 October 1795 (4 Brumaire IV under the Convention's adopted calendar).
Orchestre National de France
The orchestra was founded as the "Orchestre national" by decree on 18 February 1934, by the French minister of Posts Jean Mistler, as an ensemble of 80 musicians, with Désiré-Emile Inghelbrecht as musical director. The orchestra musicians were under exclusive engagements, prohibiting them to play with other orchestras as the orchestra of the Opera. Their first concert occurred at the Conservatoire de Paris on 13 March 1934. The main conductors in the orchestra's early years were Inghelbrecht, Roger Désormière and Eugène Bigot, as well as Inghelrecht's assistant conductor at the time, Manuel Rosenthal.
