pontiac rebellion or sons of liberty

Not to shatter any illusions, but one of the underlying motivations for the American Revolutionary War that cast off the yoke of British colonialism and set up a republic by and for the people in the face of monarchy—sorry San Marino, you apparently don’t count, before all that championing of the unreasonable nature of taxation without representation, was a touch less savoury.
Founding myths are important, obviously.  Proxy guerrilla warfare was staged against the British by competing powers in Europe—notably the French (spiraling debts incurred over these engagements led to France’s own revolution), the Spanish and the Netherlands who stood to gain with the UK tied up in internal conflicts—ensured that the conflict would continue, even after the concession of self-rule for the North American Colonies. Before these high-minded casus belli were discovered, however, it was the Crown’s irksome insistence to keep its word on treaties established with Native American tribes that was a sore point of agitation for settlers looking to expand their holdings. Because of growing tensions and potential exploitation of Indian lands, a series of royal proclamations decreed that there could be no private property deals between the colonists and Indians and that land corporations, like the Ohio and Illinois companies, would arbitrate the transactions—not that these companies were above suspicion themselves. Plantation owners seeing their aspirations mired in more bureaucracy rebelled for deed and title.
