How did attitudes toward Jews change in medieval Europe?

In medieval Europe, attitudes toward Jews shifted notably from initial coexistence to increasing hostility and discrimination. Early on, Jews were often seen as valuable for their roles in trade and finance, but growing religious fervor and economic competition led to widespread scapegoating. By the late medieval period, Jews faced violent persecution, forced conversions, and expulsions, exemplified by events like the Spanish Inquisition and the expulsion from Spain in 1492. This decline in tolerance marked a significant and tragic transformation in Jewish-European relations.
