Why did the british government issue the proclamation of 1763?

The Proclamation of 1763 was announced at the conclusion of the Indian and French War. There is some deliberation as to specifically why King George III and Britain may have announced the promulgation, but the principal cause for the announcement was that it was deemed to preserve both the colonials and the Native Westerns. The British administration did not desire American settlers traversing the Appalachian Mountains and forming anxiety with the French and Native Westerners there. The solution appeared unaffected. They originated the Royal Proclamation of 1763, which represented the beginnings of the thirteen colonists as the Appalachian Mountains.
