Why was justifying the American Revolution important?

I was always taught that a revolution was one in which its people rise up and depose the king and his leaders by either execution ( as in the French & Russian revolutions), or exile. Ours was a War for Independence, in which we separated from the "mother country,"! So, to answer your question, the justification for separation was necessary for a myriad of reasons. One being taxation without representation. ( stamp act, intolerable acts, etc..) SHS
