Explain the positive or negative impact of the proclamation of 1763

After the conclusion of the French and Indian War in America, the British Empire began to tighten control over its rather autonomous colonies. In response to Pontiac’s Rebellion, a revolt of Native Americans led by Pontiac, an Ottawa chief, King George III declared all lands west of the Appalachian Divide off-limits to colonial settlers.

This royal proclamation, issued on October 7, 1763, closed down colonial expansion westward beyond Appalachia. It was the first measure to affect all thirteen colonies. The edict forbade private citizens and colonial governments alike from buying land or making any agreements with natives; the empire would conduct all official relations. Furthermore, only licensed traders would be allowed to travel west or deal with Indians. Theoretically protecting colonists from Indian rampages, the measure was also intended to shield Native Americans from increasingly frequent attacks by white settlers. The proclamation also established three new mainland colonies: Quebec, West Florida and East Florida, while extending Georgia’s southern border and granting land to soldiers who had fought in the Seven Year's War.
