The Dreyfus Affair : a political scandal, a symbol of a judicial error that lasted twelve long years (from 1894 to 1906); France divided into two opposing camps, the Dreyfusards and the Anti-Dreyfusards ; a manifestation of anti-Semitism and nationalism ; the exemplary role of a political writer like Zola with "J'accuse".
 The National Library has archived illustrated newspapers, enabling us to follow the different phases of the trial as it happened and grasp the social and political disruption through caricatures. This also demonstrates the power of the press.
