Announced -and probably soon to be here:
1500 year old Jewish town found near Beersheva - in the 6th century CE.
Archaeologists uncovered two ritual baths and two public buildings with platforms on the Jerusalem-facing walls, indicating that they were either synagogues or Talmud schools.
It appears that the town was evacuated around the time of the Muslim invasion.
Indeed, it seems that the land of Israel had a significant - if not majority - Jewish population for centuries after the Roman conquest until the Muslim hordes came.
That was an act caused by ethnic cleansing, whether by force or economic deprivation.
So, Jews were indeed a constant demographic element in this land.
