Which of these was one of the reasons this proclamation was created?

Answer: The Missouri Compromise

Britain issued this proclamation of 1763 against the chief of Ottawa because of his various attacks.

Explanation:

Ottawa Chief Pontiac drove various assaults against British and pilgrim development and settlement and his savage hostility is one explanation Britain gave the proclamation of 1763. Pilgrim blood had been shed to battle the French and Indians, not to surrender land to them.

The declaration of 1763 was given by King Georg|| and prohibited provinces from settling land west of the Applachian mountain. The stamp demonstration was the primary direct expense by parliament on the American provinces.
