The summer of 1791 is the critical period in the fortunes of the rival parties. When the majority lost in Mirabeau their strongest leader, Robespierre, the chief of the new party, came to the front. It is difficult to resist the conclusion that at this time the future was still undecided, and the Jacobin triumph by no means secured. Had the party in power possessed a few men of practical vigour and wisdom, it seems just possible that the Revolution might have paused, and might have been guided into the path of ordered freedom. But they had no organisation. They did not see their danger. They had no experience to help them, and Mirabeau was dead. The King's unfortunate flight to Varennes in June, and the manifesto in which he set forth his grave complaints against the Revolution, played into the hands of the advanced party. It greatly increased the difficulties of the majority, who desired to keep Louis on the throne. It was followed by an outbreak of Jacobin activity, which, however, displayed many varieties of view. Danton and the Cordeliers, Brissot and Desmoulins boldly demanded the establishment of a republic, but their opinions were not shared by all their party. Marat proposed the appointment of a Dictator to put all his enemies to death. The partisans of the Duke of Orleans declared for Louis' deposition, with the object of securing the throne for the Duke. But the declarations of the Jacobin Club were curiously uncertain. They demanded Louis' deposition, but they hesitated to propose the abolition of the throne. On the 1st of July, at a session of the Club, Billaud-Varennes was not allowed even to speak on behalf of a republic. Some days later, on the evening of the 13th, influenced possibly by the reaction in the Assembly, Robespierre came forward and declared that he personally was not a republican, and that 'the word republic did not signify any particular form of government'; while even Danton avoided the question and confined himself to attacks upon the inviolability of the king.
