Book excerpt: Fifteen papers from a conference held at the University of Notre Dame in 1996 which explore the tensions that characterised the relationship between Jews and Christians across Europe during the 12th century. The movement of Jews into Slavic territories and into Anglo-Norman England also led to the creation of their own global language. Subjects include the Jewish Renaissance of the 12th century, changing perceptions of the Christian-Jewish conflict, conversion, expulsions, Christian and Jewish religious and secular texts, Jews in France and England.
