Datta (2005) shows that, following the collapse of militaristic Boulangism in the late 1880s, the Napoleonic legend was divorced from party politics and revived in popular culture. Concentrating on two plays and two novels from the periodVictorien Sardou's Madame Sans-Gene (1893), Maurice Barres's Les Deracines (1897), Edmond Rostand's L'Aiglon (1900), and Andre de Lorde and Gyp's Napoleonette (1913) Datta examines how writers and critics of the Belle Epoque exploited the Napoleonic legend for diverse political and cultural ends.
