By the 15th century, Christians, Jews and Muslims had lived side by side in Spain for centuries. The Muslims controlled a large region of modern Spain, as did the Christians. But the Jews continued to get massacred in periodic pogroms. However, there were also many rich Jews, among them the financiers who enjoyed royal favor. Then it all fell apart with Queen Isabella when she became aware of the existence of Crypto-Judaism – Jews pretending to be Christians. Jesus hates a faker.
