Nice idea, I think that surviving Latin Empire is very underused TL, mainly thanks to the dominance of Romano-/Byzantinophilia on this forum.
I've had my thoughts on this scenario before and I think that the most fitting PoD would be rather making the emperor Boniface of Montferrat, not...
All of the Southern Colonies were quite neutral during American Revolutionary War. Although their assemblies decided to join the revolution, local population wasn't enthusiastic. The same thing with the Middle Colonies, e.g. New York was viewed as a loyalist stronghold. Even in New England there...
However they were ultimately struck down by the political expansion of European settlers. If there were some actual Indian states, independent from the US, then the natives would have a chance to endure. Maybe a US-screw scenario, in which the British Indian Reserve develops into a confederacy...
With the PoD after Columbus expedition what can be done to improve the OTL situation of the indigenous inhabitant of North America (Aztecs and other Mexican tribes excluded)? Forming their own states and keeping traditional culture (Meiji-like style) would be most welcome.
More successful Spring of Nations. The Magyars are victorious and the Prussian king accepts the imperial crown, forming the German Reich which includes Austria and Bohemia. Later on it expands into Switzerland, maybe dividing it between Germany, Italy and France.
I agree, the establishment of Papal State was a crucial point. Other means we can take would be... creating another patriarchate in the West. Maybe somewhere in Gaul?
Hellenistic monarchies are more successful, the Hellenistic civilization develops onwards eventually dominating the Mediterranean world. We don't have the stagnation of late Roman Empire and future collapse of the Dark Ages. Thus Europe is more advanced a few centuries earlier and so successful...
Soviet-Platonic similarities were mostly superficial and incidental. E.g. Bolshevism didn't segregate the people into three main classes but rather tried to build mono-class society. I would rather suspect real plans to build platonic Politeia in Renaissance or even in Enlightenment (new, ideal...
Well, Plato's philosophy definitely wasn't ignored, but I don't know any serious attempts to organize society according to his ideal Politeia. And it surely has a potential to be misrepresented...
I wasn't referring only to Romans, in general other Italics and Etruscans (especially their social elites), although waging wars against Magna Grecia, were likely to adopt many elements of Greek culture. So if the Central Italy would be conquered by a Hellenistic ruler I suspect a quick...
It is possible. But it's also possible that one of the Greek states (Epirus, Syracuse or other polis) would achieve dominance over the region and establish a long-living power in Italy, spreading Greek culture up north. And do not underestimate the attractiveness of Greek culture in the eyes of...
Kind of. I was thinking about something to suppress Rome when it was still a minor player in Italy, and thus let the Greeks from Magna Grecia to live on and develop freely.
