Romantic nationalism
In his essay "De la France, de son génie et de ses destinées" (1847) he sought to give the French a sense of their essentially national destiny within the framework of Romantic nationalism. Other minor works included "Daniel Manin" (1860), "La Russie et l'Europe" (1866), "Etudes d'archéologie celtique" (1872), and "Les Napoléon et les frontières de la France" (1874).
