 James E. Lindsay also argues that the concept of an Arab identity itself did not exist until modern times.With the Umayyad Caliphate's conquest of Hispania, Muslim Arabs and Berbers overthrew the previous Visigothic rulers and created Al-Andalus, which contributed to the Golden age of Jewish culture, and lasted for six centuries.It was followed by the centuries-long "Reconquista", terminated under the Catholic monarchs Ferdinand V and Isabella I.
