Let me guess that most republics ITTL are going to be some flavor of post-colonial state or would that be a spoiler?
Well the way in which decolonization occurred in otl was never fated to happen after all as that was a consequence of both World Wars. The European powers bludgeoned each other so thoroughly that they couldn’t maintain their hold over their colonies.
The EIC's incompetent administration was the main cause of the revolt.
Fully agreed. It was getting to the point that a British takeover was all but inevitable. The Crown was already beginning to do so anyway, but the revolt really accelerated it further.
Through the revolt was mainly limited in its scope as many Indians still supported the British.
That’s also true. Though a good portion of this was more because they believed that the revolt was already doomed to failure sort of like with the Polish November Uprising of 1830. A good portion of the Polish peasantry were certainly sympathetic, but the general ineffectiveness of the rebel leadership, and the fact that defeat was all but inevitable turned them away from actively supporting the revolt. Plus a lot of the Indian Princes had been co-opted into the British/EIC’s administration. It was also why that the later Indian National Congress decided to cut the Gordon’s Knot on the whole thing and declared the Princely States abolished in favor of a Federal Republic in 1947.
I don't think that many republics would exist
Free City of Krakow: *chuckles* I’m in danger.
Napoleon II intends to integrate the colonies into his empire proper like how the Romans did with their subjects and you could see other European powers copying that kind of integration.
So maybe there won't be decolonisation.
Well there were French attempts to integrate their colonies. Initially many Algerian elites backed this idea of gaining some form of citizenship with the Algerian soldiers who fought in WW1. But when this didn’t materialize they began to move towards independence.
By the time France realized its mistake it was too late. Though I’d say the Fourth Republic had a stronger Constitution the French Union might have gotten off the ground possibly leading to something akin to a French version of the British Commonwealth of Nations.
Well I think it is going to develop into paternal autocracy with the monarch who cares for the people as his children.
This was basically how Kaiser Franz I operated. Despite how overlooked he was compared to other figures like Tsar Alexander or Napoleon, he was quite a consequential figure for Austria. With his popularity among the masses, he was able to keep his Empire together despite facing off against Napoleon. The Hungarians supported him to the hilt like they did with his grandmother Empress Maria-Theresa. When the HRE was declared dissolved riots broke out as the people thought there was some sort of conspiracy against the Emperor. And in Tyrol when Bavaria tried to occupy/govern it after Austria was forced to cede it, rebel groups emerged in favor of Austrian rule. It was so bad that the Bavarians requested French assistance in dealing with it.
Kaiser Franz also operated a highly effective surveillance apparatus against domestic threats as well. Under capable leadership Austria thrived. Where things really went wrong was where Kaiser Ferdinand took the throne. He was actually intelligent but his physical defects and frequent seizures prevented him from actually ruling. The regency council put in place was stagnant with the government essentially paralyzed for decades allowing minor issues to snowball until it emerged as the 1848 revolution.
The French Republic in this TL was shown as a period of anarchy and how Napoleon I saved the French from it by crowning himself.
Funny how history often repeats itself.
This might deter other future republics and even republics develop you might see a strongman transform into a monarchy like Napoleon I.
You could possibly have juntas simply proclaim themselves a monarchy as to try and legitimize their position rather than relying on the veil of a Republican system. Though as to how stable these “monarchies” would be is debatable as demonstrated by Iturbide’s First Mexican Empire in otl.
However the Qing are fairly doomed. If the Taiping succeed on the other hand they had a very different view at court being at least open to some western ideas (though the whole quasi-Christian cult thing would take precedence)
This is honestly quite an interdisciplinary idea to think about. If a few things change from otl you might have a “Christian” Chinese Empire emerge. Though as for how the new Emperor would reconcile things like the Emperor’s title being “the Son of Heaven” with Christian theology would be interesting. Perhaps Western ideas like Divine right might be combined with the Chinese concept of the “Mandate of Heaven” or something.
