<P> On 20 Prairial (8 June) was celebrated across the country the Festival of the Supreme Being, which was part of the Cult of the Supreme Being, a deist national religion . On 22 Prairial (10 June), the National Convention passed a law proposed by Georges Couthon, known as the Law of 22 Prairial, which simplified the judicial process and greatly accelerated the work of the Revolutionary Tribunal . With the enactment of the law, the number of executions greatly increased, and the period from this time to the Thermidorian Reaction became known as "The Grand Terror". </P> <P> On 8 Messidor (26 June), the French army won the Battle of Fleurus, which marked a turning point in France's military campaign and undermined the necessity of wartime measures and the legitimacy of the Revolutionary Government . </P> <P> The fall of Robespierre was brought about by a combination of those who wanted more power for the Committee of Public Safety (and a more radical policy than he was willing to allow) and the moderates who completely opposed the revolutionary government . They had, between them, made the Law of 22 Prairial one of the charges against him, so that, after his fall, to advocate terror would be seen as adopting the policy of a convicted enemy of the republic, putting the advocate's own head at risk . Between his arrest and his execution, Robespierre may have tried to commit suicide by shooting himself, although the bullet wound he sustained, whatever its origin, only shattered his jaw . Alternatively, he may have been shot by the gendarme Merda . The great confusion that arose during the storming of the municipal Hall of Paris, where Robespierre and his friends had found refuge, make it impossible to be sure of the wound's origin . In any case, Robespierre was guillotined the next day . </P> <P> The reign of the standing Committee of Public Safety was ended . New members were appointed the day after Robespierre's execution, and limits on terms of office were fixed (a quarter of the committee retired every three months). The Committee's powers were gradually eroded . </P>
