Which colonial group was established around 1770 in order to colonists participate in boycotts against british goods?

After the French and Indian War, Britain was the premier colonial power in North America. The Treaty of Paris (1763) more than doubled British territories in North America and eliminated the French as a threat. In efforts to keep peace with the Native Americans, the British government established the Proclamation Line in 1763, barring colonial settlement west of the Allegheny Mountains in Pennsylvania. The Proclamation declared that colonists already settled in this region must remove themselves, negating colonists’ claims to the West and thus inhibiting colonial expansion.
