Émile Zola is imprisoned in France after writing J'Accuse…!, a letter accusing the French government of antisemitism and wrongfully imprisoning Captain Alfred Dreyfus.

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.

Antisemitism or Jew-hatred is hostility to, prejudice towards, or discrimination against Jews. A person who harbours it is called an anti-Semite. Whether antisemitism is considered a form of racism depends on the school of thought. Antisemitic tendencies may be motivated primarily by negative sentiment towards Jews as a people or negative sentiment towards Jews with regard to Judaism. In the former case, usually known as racial antisemitism, a person's hostility is driven by the belief that Jews constitute a distinct race with inherent traits or characteristics that are repulsive or inferior to the preferred traits or characteristics within that person's society. In the latter case, known as religious antisemitism, a person's hostility is driven by their religion's perception of Jews and Judaism, typically encompassing doctrines of supersession that expect or demand Jews to turn away from Judaism and submit to the religion presenting itself as Judaism's successor faith—this is a common theme within the other Abrahamic religions. The development of racial and religious antisemitism has historically been encouraged by anti-Judaism, which is distinct from antisemitism itself.
