I was reading the Byzantine Empire Timeline Cliches To Avoid thread, and I figured it might be fruitful to create a similar thread for Roman Imperial timelines. I am not presently planning on writing any timeline (though I'm always toying with ideas), but nevertheless there are a lot of cliches that are bandied about. What are some that you think happen way too often or are too unrealistic? Here's a couple I came up with-they aren't exclusive to timelines, but also more generally are some "bad history" tropes about understanding the empire and how it fell.
The " One Bad Emperor" Theory of Change: The timelines where you remove an emperor like Nero or Commodus or whatever emperor you personally blame for a lot of Rome's troubles, and Rome is in a significantly better position. Particularly popular to halt the Third Century Crisis, the favorite emperor for these What Ifs is always Commodus, who create a convenient break between the last "good" emperor Marcus Aurelius and the start of all Rome's troubles heading into the Third Century. Ignoring that Commodus's "Level of Badness" for lack of a better term is often over exaggerated (he kept in place many of Marucs Aurelius's own men and his foreign policy was pretty sound, at least early on), it ignores or downplays the many structural factors that were causing the crisis-namely climate change, plague, increased and more intense threats along all of Rome's frontiers, monetary supply issues and all the imperial management issues this in turn created.
The Inevitable Principate: Even if Octavian Augustus is not the one who creates the principate, the transition from Republic to empire follows the same logic using the same terms (I am also guilty of this). It creates a sense of inevitability, that either the Caesar model or the Augustus model had to win out, even though much of Augustus's own consolidation of authority and imperial ideology was created haphazardly and on an ad hoc basis as dictated by the needs of his circumstances.
