Initially, La Marais, or The Plain, a moderate, amorphous group, controlled the Convention.
 At the first session, held on 20 September 1792, the elder statesman Philippe Rühl presided over the session.
The following day, amidst profound silence, the proposition was put to the assembly, "That royalty be abolished in France"; it carried, with cheers.
On the 22nd came the news of the Republic's victory at the Battle of Valmy.
On the same day, the Convention decreed that "in future, the acts of the assembly shall be dated First Year of the French Republic".
Three days later, the Convention added the corollary of "the French republic is one and indivisible", to guard against federalism.

The following men were elected for two-week terms as Presidents, or executives, of the Convention.

At the end of May 1793, an uprising of the Parisian sans culottes, the day-laborers and working class, undermined much of the authority of the moderate Girondins.
 At this point, although Danton and Hérault de Séchelles both served one more term each as Presidents of the Convention, the Girondins had lost control of the Convention: in June and July compromise after compromise changed the course of the revolution from a bourgeois event to a radical, working class event.
Price controls were introduced and a minimum wage guaranteed to workers and soldiers.
Over the course of the summer, the government became truly revolutionary.
