Deprived of authority and in fact a prisoner, Louis had for many months acquiesced in the decrees of the Assembly however distasteful. But the civil constitution of the clergy wounded him in his conscience as well as in his pride. From the autumn of 1790 onwards he began to scheme for his liberation. Himself incapable of strenuous effort, he was spurred on by Marie Antoinette, who keenly felt her own degradation and the curtailment of that royal prerogative which her son would one day inherit. The king and queen failed to measure the forces which had caused the Revolution. They ascribed all their misfortunes to the work of a malignant faction, and believed that, if they could escape from Paris, a display of force by friendly powers would enable them to restore the supremacy of the crown. But no foreign ruler, not even the emperor Leopold II., gave the king or queen any encouragement. Whatever secrecy they might observe, the adherents of the Revolution divined their wish to escape. When Louis tried to leave the Tuileries for St Cloud at Easter 1791, in order to enjoy the ministrations of a nonjuring priest, the National Guards of Paris would not let him budge. Mirabeau, who had always dissuaded the king from seeking foreign help, died on the 2nd of April. Finally the king and queen resolved to fly to the army of the East, which the marquis de Bouille had in some measure kept under discipline. Sheltered by him they could await foreign succour or a reaction at home. On the evening of the 20th of June they escaped from the Tuileries. Louis left behind him a declaration complaining of the treatment which he had received and revoking his assent to all measures which had been laid before him while under restraint. On the following day the royal party was captured at Varennes and sent back to Paris. The king's eldest brother, the count of Provence, who had laid his plans much better, made his escape to Brussels and joined the _emigres_.
