It was a fluke glory to the loyalists
iirc the war was originally about convincing britain to repeal the harsh taxes and policies on the american people, and the idea of independence didnt come about until later
Because russia didn't fuck their own colonies and didn't take everything they've had
Some decentralization bullshit where they make the colonies without knowledge of tribal wars, culture, relations, so war popped up often because the people were split, enemies were with enemies etc. So they left the colonies giving them "independence" but they are actually still controlled because they are entirely reliant, on the country that colonized them, in terms of money and other bullshit. Tbh idk what I'm talking about.
Different Ideologies or harshness/extortion imposed upon the colonies from the homeland is often the reason why.
