The Dreyfus affair (French: affaire Dreyfus, pronounced [afɛːʁ dʁɛfys]) was a political scandal that divided the Third French Republic from 1894 until its resolution in 1906. The scandal began in December 1894 when Captain Alfred Dreyfus, a 35-year-old Alsatian French artillery officer of Jewish descent, was wrongfully convicted of treason for communicating French military secrets to the German Embassy in Paris. He was sentenced to life imprisonment and sent overseas to the penal colony on Devil's Island in French Guiana, where he spent the following five years imprisoned in very harsh conditions.
In 1896, evidence came to light—primarily through the investigations of Lieutenant Colonel Georges Picquart, head of counter-espionage—that identified the real culprit as a French Army major named Ferdinand Walsin Esterhazy. High-ranking military officials suppressed the new evidence, and a military court unanimously acquitted Esterhazy after a trial lasting only two days. The Army laid additional charges against Dreyfus, based on forged documents. Subsequently, writer Émile Zola's open letter "J'Accuse...!" in the newspaper L'Aurore stoked a growing movement of political support for Dreyfus, putting pressure on the government to reopen the case.
