I think you'd likely see this Orthodox Yugoslavia ending up rejected by the Catholic South Slavs in favor of forming their own Illyrian Kingdom, which the Austrians would likely support as a way to both keep the Catholic Slavs in the empire out of fear of Yugoslavia and to weaken the Hungarians...
If Stalin doesn't get him later, the CIA probably assassinates him.
If he manages to survive he might indeed be able to attract some of the support that in OTL went to Maoism. Possibly negates OTL Trotskyism's development into little more than particularly aggressive pamphlet-pushers by giving...
Anything with the Balts and Slavs. Especially if they adopt or create an organized religion that is not Christianity, perhaps with some equivalent to Muhammad or them adopting something from the east rather than Christianity from the west. Especially good if the Balts, West Slavs, and East Slavs...
I've made a map - here, with frontier regions colored brighter than less vulnerable regions - illustrating what I personally view as the ideal division of the Roman Empire, which is technically a tripartite split though with different borders than OP's version. I wouldn't have it be divided into...
Neapolis near Carthage (what is Nabeul, Tunisia nowadays), or another site on the Cap Bon peninsula, would be the best fit for a Constantinople-like capital. Like Constantinople, it is on a small peninsula which is only approachable from land in one direction. This makes it very defensible...
Very interesting timeline. I especially appreciate the Info Posts.
I have to wonder how a Romanized Rashidun Caliphate, and the effects of that on Islam, would influence Christian views of Muslims. I imagine it would continue to be viewed as a relative of Christianity, like Judaism or...
The United States of America would not exist, full stop. The elites behind the (first) American War of Independence would not be given the chance to start a second one any time soon if the British are even halfway competent at colonialism, which they definitely are. They also probably wouldn't...
If I had to pick which to build and train my army, I'd go for Phillip. If I had to pick which to lead it, I'd go for Alexander. Having both of them, one right after the other, is ideal and the accomplishments of Alexander are so tied to the army built by Phillip that I can't separate them enough...
Very good point with a Chinese Australia using the Clipper route. Head east to South America through southern winds (the Roaring Forties, ideally), head west to home through the winds off Peru. Almost a perfect inverted mirror of the Spanish heading west through the Canaries to Caribbean route...
