Why did attitudes toward jews change in medieval europe?

Increased economic competition: As the European economy grew and became more complex in the Middle Ages, Jews began to play an increasingly important role in trade and finance. This led to resentment and competition from other groups, such as the Christian merchant class.

Religious intolerance: The spread of Christianity in Europe led to increased religious intolerance, and Jews were often seen as outsiders and heretics. This was exacerbated by the fact that Jews had their own distinct religion and culture, which made them easy targets for discrimination.

Political instability: The Middle Ages was a time of great political instability, and Jews were often used as scapegoats for social and economic problems. For example, during the Black Death, Jews were accused of poisoning wells and spreading the disease, and many were killed as a result.

Expulsions: As a result of these factors, Jews were often expelled from European countries. The first major expulsion occurred in England in 1290, and other countries followed suit in the centuries that followed. These expulsions had a devastating impact on Jewish communities and led to further persecution and discrimination.
