History of Jews in Spain - A Brief Timeline
"2nd Century: Romans settle the Iberian peninsula and find some Jewish families already there, some claiming to be descendants of King David who arrived after the destruction of the first Temple or during the time of Solomon and Nebuchadnezzar. Synagogues are built in the Empire's major cities. Castile is used for pastureland, as it will be used by the Visigoths and Muslims until the Christian conquest ends the wars and agriculture can be practiced safely."
