Was the Jewish population expelled from the Jerusalem after the siege of 70 AD or after the Bar Kokhba revolt?

Question

The Wikipedia article on Bar Kokhba revolt says :

and Jews were forbidden from entering it, except on the day of Tisha B'Av.

I was under the impression that the Jewish population had already been expelled after the siege of 70 AD. Or was it, that they were heavily persecuted, but not expelled in 70AD ?

Answer 1

The Jewish population was not expelled in 70. At least Josephus, our the main source on that war does not say this. Jerusalem was destroyed, and the Temple was robbed, burned and closed (closed few years after the siege). He also mentions that lands belonging to the Jews were confiscated. But he does not say that population was expelled.

Answer 2

According to Josephus's account Jerusalem was razed to the ground & most of those who didn't perish from starvation in the seige were killed defending the Temple.

From what Josephus writes it seems like there was:

1. No Jerusalem. It suffered a similar fate to Carthage by being utterly destroyed.
2. There weren't many Jews left to expel. We know many were taken as slaves back to Rome & also this conquest of Judaea funded the building of the Flavian ampitheatre, the Colosseum.
