Rilicon Sure people can leave, but emigration from established Zvlokiquix territory as shown on the map above to a brand new area would be borderline suicide. They would have no support system from the government of the country they are leaving, there isn’t currently a country to give them assistance, there would be little they could take with them, and surrounding countries would be easier immigration options. There wouldn’t be a large enough population on “Japan” that would go across the sea to start a brand new country. Sure, the majority of my population is there, but I have a lot of Pacific islands that would feel more of a disconnection from the government that I am already trying to unify.
I guess, long story short: people are allowed to leave, they could be a miniscule part of the country Rilicon, but I wouldn’t say Zvlokiquix lost a rebellion for the territory you want.
