In the aftermath of the Franco-Prussian War of 1870–71, a defeated and humiliated France split into cultural factions that ranged from those who embraced modernity to those who championed the restoration of throne and altar. This polarization—to which such iconic monuments as the Sacre-Coeur and the Eiffel Tower bear witness—intensified with a succession of grave events over the following decades: the crash of an investment bank founded to advance Catholic interests; the failure of the Panama Canal Company; the fraudulent charge of treason brought against a Jewish officer, Alfred Dreyfus, which resulted in a civil war between his zealous supporters and fanatical antagonists.
