I just hope that the Romans don't go down the same road as France when it comes to cultural homogenization. Wiping out minority languages to make everyone a Constantinopolitan doesn't sit right with me, at all.
That's where the State can intervene with tax money. Instead of the Wild West type of unrestricted development and risky behaviors that free market capitalism leads to, the Roman Empire can pick and choose what to invest in and get the best returns. State Capitalism ho!
First credit unions appeared in the mid 19th century in our history. Seems like the Romans will have a healthy middle class come Industrial Revolution.
Roman Empire not owning Rome will be an endless thorn in the side of Roman Nationalism, because the western Europeans will just point at the place and say that those guys are the actual Romans.
It should be kept as part of the Empire just for that reason.
EDIT: Also on another note, is the...
Some form of divisions of power presumably, making the empire a hell of a lot more legalistic and formalized. An autocrat at the center but with clearly defined for civil servants and soldiers. Constitutional Autocracy?
I feel Gyranos will turn on Constantinople, perhaps following the example of the end of the War of Five Emperors.
A weak possibility since his opponent just gave up land to the Ottomans, but still.
Easiest way (well, "easy") would be for the Romans to pay off the Russians and Japanese and make Koreans a Roman ally or client state or something, with the understanding that Korea will not be used by either side to undermine the other while keeping it in friendly hands.
There was a future snippet posted in the last thread from the perspective of a Triune American historian. If that was representative of what Triune Americans become, then the North American natives are going to be gone by the time 1900 rolls around.
Catherine the Great got started like this. Her husband was an imbecile who actively sabotaged Russia because he was a fan of Frederick the Great of Prussia, so she led a palace coup against him and took over.
Whatever else, I think the Imperial Family will start very strongly vetting any affairs that the family members have. And maybe start pushing for harsh laws against grooming and marriages with significant gaps in age.
If USSR survives then the cheap Soviet chemical fertilizer aid to North Korea will continue, and the Arduous March won't take place. Not suffering a mass famine and breakdown of the entire economy would certainly improve the place.
