J'Accuse

Émile Zola wrote an open letter, "J'Accuse...!", published in the newspaper L'Aurore on January 13, 1898, which accused the French government of antisemitism and the unlawful jailing of Alfred Dreyfus, a French Army General Staff officer. Zola pointed out judicial errors and lack of serious evidence in Dreyfus's conviction for espionage, which was largely based on handwriting analysis and confidential testimony. The letter caused a stir in France and abroad, leading to Zola's prosecution for libel and his eventual exile to England, but ultimately contributed to the annulment of Dreyfus's conviction and his exoneration in 1906.learn more on wikipedia
