It was the "Sons of Liberty" that was the organization that specifically promoted support for the war against the British among the american people, mainly due to grievances over taxation.
The proclamation of 1763 forbade colonists from crossing the appalachian mountains, because Great Britain decided that if the colonists took too much land, the Indians would attack, and Britain did not want to be at war with the Indians, especially after the costly fight with France, which left their coffers (money) empty
