Flavien Bertran de Balanda is a historian and associate researcher at the Centre d’histoire du xixe siècle (Center for 19th-Century History) at Sorbonne Université. His research primarily focuses on Louis de Bonald, to whom he devoted his dissertation and various publications. He has also worked on various projects for critical editions of his texts. This activity is part of a broader project entitled  “Violence(s) et légitimité(s). Redéfinitions conceptuelles du politique dans la France postrévolutionnaire 1796-1871,” which explores nineteenth-century political philosophy (Chateaubriand, Mme de Staël, etc.), and the process of legitimization as well as symbolic and discursive protest, especially as revealed by the question of censorship, its circumvention, and the polemical and satirical press. He co-founded the Society for Bonaldian Studies, and co-directs the Louis de Bonald/Maurice de Bonald archives conserved at the Monna family domain (Millau).
