Suddenly, when Mazarin's government appeared most firmly rooted, there was an explosion which threatened to change the whole face of France. An outcry arose for placing restrictions upon rights of the crown, for establishing constitutional and individual liberties. The Fronde, as the party which uttered the cry was called, did its best to imitate the English Long Parliament whose deeds were then ringing through the world. But there were no elements in France upon which to establish constitutional government. The Parliament of Paris, which wished itself to be considered the chief organ of that government, was a close corporation of lawyers, who had bought or inherited judicial places; and of all governments, a government in the hands of a close corporation of lawyers is likely, in the long run, to be the most narrow-minded and unprogressive of all possible combinations; for it is the business of a lawyer to administer the law as it exists, not to modify it in accordance with the new facts which rise constantly to the surface of social and political life. Nor were the lawyers of the parliament fortunate in their supporters. The Paris mob, combined with a knot of intriguing courtiers, could form no firm basis for a healthy revolution. It was still worse when Condé, quarrelling on a personal question with Mazarin, raised the standard of aristocratic revolt, and threw himself into the arms of the Spanish invader. Mazarin and the young king represented the nation against aristocratic selfishness and intrigue; and when they obtained the services of Turenne, the issue was hardly doubtful. In 1652 Lewis XIV. entered Paris in triumph. In 1653 Condé, in conjunction with a Spanish army, invaded France, and pushed on hopefully for Paris. But Turenne was there with a handful of troops; and if Condé was the successor of Gustavus in the art of fighting battles, Turenne was Wallenstein's successor in the art of strategy. Condé could neither fight nor advance with effect. The siege and reduction of Rocroy was the only result of a campaign which had been commenced in the expectation of reducing France to submission. [Sidenote: § 4. The war with Spain.] In 1654 Condé and the Spaniards laid siege to Arras, whilst the French were besieging Stenay. Stenay was taken; Arras was relieved. In 1655 further progress was made by the French on the frontier of the Netherlands; but in 1656 they failed in the siege of Valenciennes. [Sidenote: § 5. France, Cromwell, and Spain.]
