Explanation: The Third (and final) Jewish-Roman War occurred when the Emperor Hadrian had just finished deifying his then-dead 19-year old boytoy a few months before (problematic in its own right considering Hadrian’s age, but the past is a shitty place). The Emperor Hadrian was also infamous for his short-temper and his… direct approach to threats.
For obvious reasons, the Third Jewish-Roman War did not end well for the Iudeans.
Other issues could have contributed to the outbreak: a heavy-handed, culturally insensitive Roman administration; tensions between the landless poor and incoming Roman colonists privileged with land-grants
A heavy-handed security presence over an indigent people, while divvying up their land to be occupied… where have I heard this before??
The full history of it is darker and more complex.
Roman cultural insensitivity was legendary though. “Why do we need to understand the barbarians? It’s not like they have anything useful to say” Roman governor after Roman governor says, after moving statues of the gods into Jewish holy places, and then being utterly confused as to why the Jews are ungrateful for the gift honoring the gods.
It helps if it’s not the third one, too.
