Answer: Proclamation at the end of the French and Indian wars.
Step-by-step explanation:
The proclamation of 1763 took place at the end of the French and Indian wars. The British authorities thus intended to draw a line of demarcation between the colonies and the Indian country. The created border separated the colonies on the Atlantic coast from the countries inhabited by American natives west of the Appalachian Mountains. The reason for this move of the colonial government lies in response to the revolts of the native population and the efforts to raise the security in the colonies to a higher level.
