Final answer:
The Proclamation Line of 1763 was issued by the British to prevent further conflicts between colonists and Native Americans and to keep colonists east of the Appalachian Mountains. It followed Britain's debt from the Seven Years' War and was seen as a temporary peacekeeping measure.
Step-by-step explanation:
The British Government issued the Proclamation Line of 1763 primarily to prevent more wars between the colonists and Native Americans by making it illegal to move past the Appalachian Mountains. The intention was to keep the colonists on the eastern seaboard, avoid further conflicts, and reduce the costs of defending the frontier, especially since Britain was already struggling with debt from the Seven Years' War.
This strategy was seen as part of a temporary measure to pacify the Native Americans and set the stage for a more permanent policy. However, the colonists, expecting to expand westward after the Seven Years' War, viewed the Proclamation as an act of tyranny, leading to growing dissatisfaction with British rule.
