Antisemitism in France is the expression through words or actions of an ideology of hatred of Jews on French soil.
Jews were present in Roman Gaul, but information is limited before the fourth century. As the Roman Empire became Christianized, restrictions on Jews began and some emigrated to Gaul. In the Middle Ages, France was a center of Jewish learning, but over time, persecution increased, including multiple expulsions and returns.
The history of the Jews in France deals with Jews and Jewish communities in France since at least the Early Middle Ages. France was a centre of Jewish learning in the Middle Ages, but persecution increased over time, including multiple expulsions and returns. During the French Revolution in the late 18th century, on the other hand, France was the first European country to emancipate its Jewish population. Antisemitism still occurred in cycles and reached a high in the 1890s, as shown during the Dreyfus affair, and in the 1940s, under Nazi occupation and the Vichy regime.
Before 1919, most French Jews lived in Paris, with many being very proud to be fully assimilated into French culture, and they comprised an upscale subgroup. A more traditional Judaism was based in Alsace-Lorraine, which was recovered by The German Empire in 1871 and taken by France in 1918 following World War I. In addition, numerous Jewish refugees and immigrants came from Russia and eastern and central Europe in the early 20th century, changing the character of French Judaism in the 1920s and 1930s. These new arrivals were much less interested in assimilation into French culture. Some supported such new causes as Zionism, the Popular Front and communism, the latter two being popular among the French political left.
Alfred Dreyfus (9 October 1859 – 12 July 1935) was a French Army officer best known for his central role in the Dreyfus affair. In 1894, Dreyfus fell victim to a judicial conspiracy that eventually sparked a major political crisis in the French Third Republic when he was wrongfully accused and convicted of being a German spy due to antisemitism. Dreyfus was arrested, cashiered from the French army and imprisoned on Devil's Island in French Guiana. Eventually, evidence emerged showing that Dreyfus was innocent and the true culprit was fellow officer Ferdinand Walsin Esterhazy.
Gradual revelations indicated that the internal investigation conducted by the French army was biased; Dreyfus was an ideal scapegoat due to being a Jew, and military authorities were aware of his innocence but chose to cover up the affair and leave him imprisoned rather than lose face. A political scandal subsequently erupted, shaking French political life and highlighting antisemitism in the French army and government. After numerous judicial and political developments, the publication of Émile Zola's manifesto J'Accuse...! in 1898 brought new momentum to Dreyfus' cause. Zola accused French military and political leadership of covering up the affair. Dreyfus was eventually exonerated, rehabilitated and reinstated in the French army, although at a lower rank than his seniority would have warranted.
