In 1631 there had been a great effervescence of the French feudal aristocracy against the royal authority. But Richelieu stood firm. In March the king's brother, Gaston Duke of Orleans, fled from the country. In July his mother, Mary of Medici, followed his example. But they had no intention of abandoning their position. From their exile in the Spanish Netherlands they formed a close alliance with Spain, and carried on a thousand intrigues with the nobility at home. The Cardinal smote right and left with a heavy hand. Amongst his enemies were the noblest names in France. The Duke of Guise shrank from the conflict and retired to Italy to die far from his native land. The keeper of the seals died in prison. His kinsman, a marshal of France, perished on the scaffold. In the summer of the year 1632, whilst Gustavus was conducting his last campaign, there was a great rising in the south of France. Gaston himself came to share in the glory or the disgrace of the rebellion. The Duke of Montmorenci was the real leader of the enterprise. He was a bold and vigorous commander, the Rupert of the French cavaliers. But his gay horsemen dashed in vain against the serried ranks of the royal infantry, and he expiated his fault upon the scaffold. Gaston, helpless and low-minded as he was, could live on, secure under an ignominious pardon. [Sidenote: § 5. Richelieu did for France all that could be done.] It was not the highest form of political life which Richelieu was establishing. For the free expression of opinion, as a foundation of government, France, in that day, was not prepared. But within the limits of possibility, Richelieu's method of ruling was a magnificent spectacle. He struck down a hundred petty despotisms that he might exalt a single despotism in their place. And if the despotism of the Crown was subject to all the dangers and weaknesses by which sooner or later the strength of all despotisms is eaten away, Richelieu succeeded for the time in gaining the co-operation of those classes whose good will was worth conciliating. Under him commerce and industry lifted up their heads, knowledge and literature smiled at last. Whilst Corneille was creating the French drama, Descartes was seizing the sceptre of the world of science. The first play of the former appeared on the stage in 1629. Year by year he rose in excellence, till in 1636 he produced the 'Cid;' and from that time one masterpiece followed another in rapid succession. Descartes published his first work in Holland in 1637, in which he laid down those principles of metaphysics which were to make his name famous in Europe. [Sidenote: § 6. Richelieu and Germany.]
