Final answer:
The British Proclamation of 1763 was designed to prevent bloodshed and costly wars with Native American tribes by forbidding British colonists from settling west of the Appalachian Mountains, fueling colonial discontent in the aftermath of the Seven Years' War.
Step-by-step explanation:
Reasons for the British Proclamation Limiting Westward Expansion
The British government issued the Proclamation of 1763 to limit westward expansion and mitigate tensions on the frontier. This proclamation established the Proclamation Line along the Appalachian Mountains, restricting British colonists from settling west of this boundary. One overarching reason was to prevent bloodshed and costly wars with Native American tribes who lived west of the Appalachians. Additionally, the aftermath of the Seven Years' War left Britain eager to avoid further military expenses and to appease Native American allies by protecting their lands from colonial encroachment. Many colonists were frustrated by the proclamation as they had anticipated the opportunity to expand westward after Britain's victory over France, thus contributing to rising dissatisfaction with British rule and laying the groundwork for the American Revolution.
