I want to know the answer to the following question:
What year was Victorien Sardou's Madame Sans-Gêne written?
All the background I'm provided with is that "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.". Is that enough to answer the question?
Answer: no
