Royer-Collard himself, Jean Maximilien Lamarque and Maine de Biran had sat in the revolutionary Assemblies. Pasquier, the comte de Beugnot, the baron de Barante, Georges Cuvier, Mounier, Guizot and Decazes had been imperial officials, but they were closely united by political principle and also by a certain similarity of method. Some of them, notably Guizot and Maine de Biran, were theorists and commentators on the principles of government. The baron de Barante was an eminent man of letters. All were noted for the doctrinal coherence of their principles and the dialectical rigidity of their arguments. The object of the party as defined by the future duc Decazes was to "nationalize the monarchy and to royalize France". The king, who had been king of France during the Ancien Régime, ultimately became king of the French under the July Monarchy. This illustrated the change from the divine right of kings to national sovereignty as sovereignty was not derived from God anymore, but from the people.
