From all the different civilizations, cultures, identities and religions present in Spanish history, the one with the longest presence in time is Judaism. This also applies to Jewish identity today. The contribution to Judaism made by the Iberian Jewish community during its Golden Age either under Muslim or Christian rulers is very significant. Jewish identity would not be as rich and diverse as it is today without the philosophy, religious poetry, literature, liturgy and science developed by Jews in Spanish Middle Ages. It is also relevant that although life for religious minorities was sometimes very challenging, we cannot find in history a similar cultural exchange between Jewish, Christian and Muslim intellectuals. A better understanding of this heritage and of the coexistence of people of different faith can be an inspiration for us today.
