Abstract: While Germaine de Staël completes the Considérations, in the end of 1816, the Ultra-royalists represent the biggest opposition to the French constitutional monarchy. Yearning to go back to the Ancien Régime, willing for the Catholic Church to regain her influence, the Ultra-royalists generate Staël’s downright hostility. This paper intends to explore Staël’s criticism of the Ultra-royalists religious system and the rhetorical tools she uses to prove the relevance of her position.
