The Dreyfus Affair, 1894 to 1906

What happened

Alfred Dreyfus was born in Mulhouse, in Alsace, on October 9, 1859, the youngest of nine children of a textile manufacturer. ¹ The family moved to Paris in 1871, after the Franco-Prussian War. ¹ He graduated from the École Polytechnique in 1880, made lieutenant in 1885 and captain in 1889, and by 1893 he was the only Jew serving on the French Army's General Staff. ¹

In 1894 French intelligence recovered a handwritten memo, the bordereau, offering French military secrets to the German embassy in Paris. ¹ A French spy at the embassy found the torn-up note in a wastebasket, and the handwriting was said to resemble Dreyfus's. ⁵ He was arrested on October 15, 1894, and court-martialed. ¹ The tribunal saw secret documents that his lawyer was never allowed to review, some of them forged. ¹ He was convicted and sentenced to life imprisonment. ¹

On January 5, 1895, the army stripped him of rank in public. ¹ His insignia were torn off and his sword broken in front of a crowd that shouted "Death to Judas, death to the Jew." ⁵ Dreyfus called out that they were degrading an innocent man, and then "Long live France! Long live the army!" ¹ Édouard Drumont's antisemitic paper La Libre Parole had been driving the story and stoking the hostility of the crowds. ¹ Dreyfus was shipped to a penal colony on Devil's Island, off the coast of French Guiana. ¹

In March 1896, Lieutenant Colonel Georges Picquart, the army's new intelligence chief, established that the bordereau had been written by Major Ferdinand Walsin Esterhazy. ¹ The army transferred Picquart to North Africa and later imprisoned him. ⁵ Esterhazy was court-martialed in 1898, acquitted, and left France. ⁵

The novelist Émile Zola then forced the case into the open. On January 13, 1898, the newspaper L'Aurore published his open letter to President Félix Faure under the title "J'Accuse...!" ² Zola named officers and officials and accused them of conspiring to keep an innocent man convicted, describing the case as a crime that hid behind antisemitism. ² It sold 200,000 copies in Paris. ³ Zola was prosecuted for libel, convicted, and went to England. ^{2 5}

The evidence collapsed in the summer of 1898, when the forgeries were exposed. ¹ One central document was found to be, in the words used at the time, a clumsy forgery, and Colonel Henry, the officer behind it, killed himself in prison. ³ Dreyfus was brought back for a second court-martial at Rennes in August and September 1899. ¹ The court convicted him again and cut his sentence. ¹ President Émile Loubet pardoned him on September 20, 1899. ¹

A pardon is not an acquittal, and the difference took another seven years to close. ³ On July 12, 1906, Dreyfus was officially exonerated, reinstated as a major, and made a knight of the Legion of Honor. ¹ He served in the French army in the First World War and was promoted to lieutenant colonel at the end of it. ¹ He died on July 12, 1935, at 75. ¹

Why it still matters

The case split France into two camps. The Dreyfusards were writers, artists, scientists, and anticlerical republicans who held that a state convicting a man on secret evidence had stopped being a republic. ² The anti-Dreyfusards were the military hierarchy, the Catholic Church, and the monarchists, whose strongest argument was that reopening the case would break public confidence in an army France believed it needed. ² Their weakest argument ran in the Catholic paper La Croix, which called for expelling Jews from France. ² Our view: the army had a real interest in its own credibility, and it spent that credibility keeping an innocent officer on a prison island.

The political consequences ran for years. René Waldeck-Rousseau became prime minister in 1899, and his government passed the 1901 Law of Associations, requiring state authorization for religious teaching orders. ² In 1905 parliament passed the Law of Separation of the Churches and the State, ending the 1801 Concordat that had given certain confessions official standing. ² French secularism took much of its present shape in the years the affair was being fought out. ²

Dreyfus was an assimilated French Jew and a career officer of the republic. The affair shocked Jewish communities well beyond France. It showed that assimilation was no protection against antisemitism. ³ Theodor Herzl witnessed the affair. He published Der Judenstaat in 1896 and convened the first Zionist Congress in Basel in 1897. ^{1 4}

The line from Dreyfus to Zionism is real, and it is also argued over. The conventional account credits the 1894 trial with converting Herzl. ⁴ Later scholars have argued that his shift came earlier, and that he emphasized Dreyfus afterward because it made a more persuasive story for the movement he was building. ⁴ That dispute concerns Herzl's own timeline. It does not change what the rest of European Jewry took from the case, which was a French officer convicted on a forgery while a Paris crowd shouted about Judas. ^{3 5}

France has kept returning to the case. On November 17, 2025, President Emmanuel Macron and Prime Minister Sébastien Lecornu signed into law a bill posthumously promoting Dreyfus to brigadier general, published in the Official Journal the next day. ⁶ The statute reads: "The French nation posthumously promotes Alfred Dreyfus to the rank of brigadier general." ⁶ The lower house had approved it unanimously in June 2025 and the Senate that November. ⁶ It passed while antisemitic hate crimes were rising against the largest Jewish community in Europe. ⁶
