Most studies of medieval Jews focus on Jewish-Christian relations or follow a "decline towards persecution and expulsion" narrative. Ray's mission is to focus on Jewish life for its own sake. He discusses how Jewish communities thrived and suffered in the wake of the Christian conquest of Iberia. Most importantly, Ray takes us inside the communities themselves to show how they governed, disagreed, fought bitterly, cooperated, splintered, took risks, and worked oppressive systems to their advantage. He's even able to show differences between religious scholars' legal decisions and the day-to-day actions of elite and common members of Jewish society.
