French culture was part of French hegemony. In the early part of the century French painters had to go to Rome to shed their provinciality (Nicolas Poussin, Claude Lorrain), but Simon Vouet brought home the taste for a classicized baroque that would characterise the French Baroque, epitomised in the Académie de peinture et de sculpture, in the painting of Charles Le Brun and the sculpture of François Girardon. With the Palais du Luxembourg, the Château de Maisons and Vaux-le-Vicomte, French classical architecture was admired abroad even before the creation of Versailles or Perrault's Louvre colonnade. Parisian salon culture set standards of discriminating taste from the 1630s, and with Pascal, Descartes, Bayle, Corneille, Racine and Molière, France became the cultural center of Europe. In an effort to prevent the nobility from revolting and challenging his authority, Louis implemented an extremely elaborate system of court etiquette with the idea that learning it would occupy most of the nobles' time and they could not plan rebellion. By the start of the 18th century, the nobility in France had been effectively neutered and would never again have more power than the crown. Also, Louis willingly granted titles of nobility to those who had performed distinguished service to the state so that it did not become a closed caste and it was possible for commoners to rise through the social ranks. The king sought to impose total religious uniformity on the country, repealing the Edict of Nantes in 1685. The infamous practice of dragonnades was adopted, whereby rough soldiers were quartered in the homes of Protestant families and allowed to have their way with them. Scores of Protestants fled France, costing the country a great many intellectuals, artisans, and other valuable people. Persecution extended to unorthodox Catholics like the Jansenists, a group that denied free will and had already been condemned by the popes. Louis was no theologian and understood little of the complex doctrines of Jansenism, satisfying himself with the fact that they threatened the unity of the state. In this, he garnered the friendship of the papacy, which had previously been hostile to France because of its policy of putting all church property in the country under the jurisdiction of the state rather than of Rome.
