Huh? I have to be reading this wrong. There is no way anyone believes the colonies did not know they were under British control considering, oh I don't know, the founding colonial charters pretty much spelled it out with ink.
My bad, Mr. Huskerblitz. Probably I did not make myself clear. English is not my first language and I make grammatical errors here and there.
The 13 American colonies did not signed up for royal charters like at their will, did they? They were 'granted' a right to be a colony. Is it correct to assume that it was an entirely different process with ratifying a constitution that those colonies did later on? Therefore, American Revolution was not unilateral secession, but more of rebellion against the Crown.
