After World War I, Jewish writers began articulating a new, cultural definition of what it meant to be a Jew within the context of French Third Republic universalism.

Given their connection to France, Fleg's family expressed a strong loyalty to the emancipatory values of the French Revolution when Jews were granted full citizenship.

As French-identified Jews, Fleg's parents found the principles of Judaism as they understood them to be identical with the liberal ideals of the French revolution: tolerance, equality, and freedom.

[5] He began his formal education, first, in Paris at the Lycée Louis Le Grand and then at École Normale Supérieure.

His work was influenced by the disturbances caused by the Dreyfus affair, by his participation in the Third Zionist Congress in Basel and by the reports of pogroms.

His 1960 work Vers le Monde qui vient gave his message of hope with which he wanted to build a bridge to Christianity.

[8] Edmond Fleg's writing can be divided into three main categories: religious poetry, biographical works, and autobiographical and other essays on Jewish themes.

Considered to be one of France's leading writers, he authored countless essays, 17 plays and operas, 10 books of poetry and four novels.
