Émile Zola's J'accuse…! exposes the Dreyfus affair.

Émile Édouard Charles Antoine Zola was a French novelist, journalist, playwright, the best-known practitioner of the literary school of naturalism, and an important contributor to the development of theatrical naturalism. He was a major figure in the political liberalization of France and in the exoneration of the falsely accused and convicted army officer Alfred Dreyfus, which is encapsulated in his renowned newspaper opinion headlined J'Accuse...!  Zola was nominated for the first and second Nobel Prizes in Literature in 1901 and 1902.

"J'Accuse...!" is an open letter, written by Émile Zola in response to the events of the Dreyfus affair, that was published on 13 January 1898 in the newspaper L'Aurore. Zola addressed the president of France, Félix Faure, and accused his government of antisemitism and the unlawful jailing of Alfred Dreyfus, a French Army General Staff officer who was sentenced to lifelong penal servitude for espionage, and sent to the penal colony on Devil's Island in French Guiana. Zola pointed out judicial errors and lack of serious evidence during Dreyfus' trial. The letter was printed on the front page of the newspaper, and caused a stir in France and abroad. Zola was prosecuted for libel and found guilty on 23 February 1898. To avoid imprisonment, he fled to England, returning home in June 1899.

The Dreyfus affair 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.
