The Torah has always been the general law of the Jews, being the moral and civil base of the whole development of that society, which has always remained united around these principles. The Jewish beginning came near the lands of Jerusalem, when they were expelled from there by the Romans came to occupy the regions of Turkey, Egypt, Greece, and south of the Italian peninsula. After that period it occupied the regions to the northwest of Africa, as well as the south of Spain, France and, at the end of the Roman period already it was possible to find Jews to the north of France and even in Great Britain.
Hope this helps.
