Why did england pass the proclamation of 1763?

because the small british army could not fight the war and keep settlers out of the new territory
to provide for orderly settlement of new territories
to establish peace with the native tribes

To establish peace with native tribes is the correct answer.

Explanation:

The proclamation act of 1763 was issued by the King George Third on 7th October 1763 when the British acquired French territories in North America when the French and Indian wars ended. The proclamation act cancelled all the land grants which were given to the British who fought for the crown and also disallowed to settlements on the west of Appalachian mountains. The west of the Appalachian mountains was declared Indian reserves. The act angered the colonialists and led to Pontiac's rebellion. The act gave the crown monopoly on all future land purchases from the American Indians.
