I'm pretty sure the British Empire colonised America, then some little knacker upstarts decided they didn't wanna pay the Crown anymore.
Essentially, America was founded by tax defaulters who owned slaves.
Our independence mostly comes down to our GOD GIVEN RIGHT TO SMUGGLE, to avoid paying taxes on goods after the Seven Years War.
Colonial courts were very forgiving to suspected smugglers, the sugar act of 1764 actually took away the jurisdiction of colonial courts in these cases, crown courts carried out trails for smuggling. Colonial courts were lenient on smugglers, who doesn't like super cheap goods? Taxes on molasses from .06¢ to .03¢ per gallon, VERY OPPRESSIVE. This angered people enough because they started enforcing the taxes and began actually jailing smugglers.
Then came the stamp act. Then that repealed quickly. Declatory act, HAHAHA!
Then Towenshend Acts, can't have that, interferes with our smuggling again.
'Whelp, I guess we should all get drunk and start a war. I need to get back to smuggling, let's make it quick!'
MURICA! Fuck taxes! . . . Until we need to pay for a war. A bit like a teenager who is going through a rough time, body is changing, thinks his Dad George doesn't spend enough time with him. We start sneaking about and acting out. Daddy neglected us too long after we started sneaking out of the house. He didn't treat us like an adult, how could he? We were acting like assholes, but he didn't need to be so firm.
Also, it makes no sense for an isle to govern a continent.
