Quick summary of a story in Tacitus, Annales 6

A tyrant is removed from Mesopotamia thanks to the intervention of a western empire, escaping with a select bodyguard to parts unknown, but those left out of the new regime stir up the populace against the new leader, at first welcomed eagerly, but because he has lived in the west for many years he is criticized as too foreign and a puppet. And so the tyrant returns to power.

I'm just saying.
