Hello this is social studies its about the proclamation 1763. ultimately, why do you think this proclamation was written?

The major purpose of the Proclamation of 1763 was to maintain good relations between the British and the Native Americans. We can also speculate that a secondary purpose was to exert British control over the colonists. Neither purposewas achieved to any great degree.   

also in other wordsIn 1763, at ethe end of the French and Indian War, the British issued aproclamation,mainly intended to conciliate the Indians by checking the encroachment of settlers on their lands. In the centuries since the proclamation, it has become one of the cornerstones of Native American law in the United States and Canada.

hope i helped!
