The Dreyfus Affair (French: l'affaire Dreyfus, pronounced [la.fɛʁ dʁɛ.fys]) was a political scandal that divided the Third French Republic from 1894 until its resolution in 1906. The affair is often seen as a modern and universal symbol of injustice, and it remains one of the most notable examples of a complex miscarriage of justice. The major role played by the press and public opinion proved influential in the lasting social conflict.
The scandal began in December 1894 with the treason conviction of Captain Alfred Dreyfus, a young French artillery officer of Alsatian and Jewish descent. Sentenced to life imprisonment for allegedly communicating French military secrets to the German Embassy in Paris, Dreyfus was imprisoned on Devil's Island in French Guiana, where he spent nearly five years.
Evidence came to light in 1896—primarily through an investigation instigated by Georges Picquart, head of counter-espionage—identifying a French Army major named Ferdinand Walsin Esterházy as the real culprit. After high-ranking military officials suppressed the new evidence, a military court unanimously acquitted Esterházy after a trial lasting only two days. The Army then accused Dreyfus with additional charges based on falsified documents. Word of the military court's framing of Dreyfus and of an attempted cover-up began to spread, chiefly owing to J'accuse, a vehement open letter published in a Paris newspaper in January 1898 by famed writer Émile Zola. Activists put pressure on the government to reopen the case.
