Rishonim
In medieval Paris, under the rule of French kings whose authority grew steadily from the early twelfth century onward, a thriving Jewish community occupied the Rue de la Juiverie on the Île de la Cité, their quarter lying in the shadow of Notre-Dame. The Jews of Paris were merchants, moneylenders, and above all scholars—the city became a vital center of Tosafist learning, where rabbis engaged in the intricate, argumentative methodology of textual analysis that defined Ashkenazi Judaism. Rabbeinu Yehiel of Paris, the towering figure of the thirteenth century, led a flourishing yeshiva whose students traveled from across northern Europe to study with him, and his Tosafot—glosses challenging and refining the interpretations of earlier authorities—circulated widely in manuscript. Yet this golden age of intellectual ferment was shadowed by persecution: Jews faced conversion pressures, violent accusations of ritual murder, and royal expulsions and readmissions that made their tenure always precarious. The Great Disputation of 1240, in which Yehiel publicly defended Judaism against Christian charges in the royal court itself, became legendary—a moment when Paris's Jewish scholars could still imagine they might argue their way to safety through reason and eloquence.
