Why were the colonists upset about the proclamation of 1763

Te proclamation of 1763 by the British parliament was aimed to create a separating line between the Native Americans and white settlers and Appalachian Mountain was set as the separating line. They called all the white settlers west of the mountain to move East and to pay for the war debt of the French and Indian war. These efforts to tighten their control on the white settlers and to tax them for the war dept resulted in the resentment of the colonists and later for revolution.
