The situation of France, which was serious before, now became desperate; for the Girondins, escaping from their arrest, called the departments to arms against Paris. Normandy, Bordeaux, Marseilles, Lyons, rose in insurrection against the tyranny of the Mountain, and the Royalists of the south and west threw themselves into a civil war which they hoped to turn to their own advantage. But a form of government had now arisen in France well fitted to cope with extraordinary perils. It was a form of government in which there was little trace of the constitutional tendencies of 1789, one that had come into being as the stress of conflict threw into the background the earlier hopes and efforts of the Revolution. In the two earlier Assemblies it had been a fixed principle that the representatives of the people were to control the Government, but were not to assume executive powers themselves. After the overthrow of Monarchy on the 10th August, the Ministers, though still nominally possessed of powers distinct from the representative body, began to be checked by Committees of the Convention appointed for various branches of the public service; and in March, 1793, in order to meet the increasing difficulties of the war, a Committee of Public Safety was appointed, charged with the duty of exercising a general surveillance over the administration. In this Committee, however, as in all the others, the Gironde were in the majority; and the twenty-four members who composed it were too numerous a body to act with effect. The growing ascendancy of the Mountain produced that concentration of force which the times required. The Committee was reduced in April to nine members, and in this form it ultimately became the supreme central power. It was not until after the revolt of Lyons that the Committee, exchanging Danton's influence for that of Robespierre, adopted the principle of Terror which has made the memory of their rule one of the most sinister in history. Their authority steadily increased. The members divided among themselves the great branches of government. One directed the army, another the navy, another foreign affairs; the signature of three members practically gave to any measure the force of law, for the Convention accepted and voted their reports as a matter of course.
