Why did the Proclamation of 1763 lead to colonial dissatisfaction?

The Proclamation of 1763, issued by the British government, restricted colonial expansion westward beyond the Appalachian Mountains to appease Native American tribes and avoid further conflicts. Colonists, eager for land and economic opportunities, felt their rights to explore and settle new territories were being unjustly limited. This perceived overreach by the British government fueled resentment and contributed to growing tensions between the colonies and Britain, ultimately sowing the seeds of revolution.
