On December 22, 1894, a closed military court-martial in Paris convicted Captain Alfred Dreyfus of treason and sentenced him to deportation for life. Dreyfus, a 35-year-old artillery officer of Alsatian Jewish descent, was accused of passing French military secrets to the German Embassy.

The case rested on flimsy and partly forged evidence, kept secret even from the defense. Dreyfus was publicly stripped of his rank and shipped to the brutal penal colony of Devil’s Island in French Guiana, where he spent nearly five years.

The verdict split France for more than a decade. The injustice mobilized writers and reformers, most famously novelist Émile Zola, whose 1898 open letter J’Accuse…! accused the army of a cover-up. Mounting proof of Dreyfus’s innocence finally led to his exoneration in 1906. The affair laid bare the antisemitism running through French institutions and remains a touchstone for debates about justice.
