Answer:The TREATY OF PARIS, which marked the end of the French and Indian War, granted Britain a great deal of valuable North American land. But the new land also gave rise to a plethora of problems.
The ceded territory, known as the Ohio Valley, was marked by the APPALACHIAN MOUNTAINS in the east and the Mississippi River in the west.

Despite the acquisition of this large swath of land, the British tried to discourage American colonists from settling in it. The British already had difficulty administering the settled areas east of the Appalachians. Americans moving west would stretch British administrative resources thin.
Further, just because the French government had yielded this territory to Britain did not mean the Ohio Valley's French inhabitants would readily give up their claims to land or trade routes. Scattered pockets of French settlers made the British fearful of another prolonged conflict. The war had dragged on long enough, and the British public was weary of footing the bill.

Even after Britain issued the Royal Proclamation of 1763, Daniel Boone continued to settle areas west of the Appalachian Mountains. This 1851 painting, Daniel Boone Leading Settlers through the Cumberland Gap, depicts the popular image of a confident Boone leading the early pioneers fearlessly into the West.
Moreover, the Native Americans, who had allied themselves with the French during the Seven Years' War, continued to fight after the peace had been reached. Pontiac's Rebellion continued after the imperial powers achieved a ceasefire.
The last thing the British government wanted were hordes of American colonists crossing the Appalachians fueling French and Native American resentment.
The solution seemed simple. The ROYAL PROCLAMATION OF 1763 was issued, which declared the boundaries of settlement for inhabitants of the 13 colonies to be Appalachia.
