After winning the French & Indian War, Great Britain passed the Proclamation of 1763 which made the colonists angry because

it did not allow them to settle on land west of the Appalachian mountains.

Explanation:

The French and Indian War was developed between 1754 and 1763. The fight was Great Britain against the French and the different tribes of native Americans. They were fighting for the expansion of their territories.  

The war was won by Great Britain after the signing of the Treaty of Paris, France ceded various territories to Great Britain, and a new territorial disposition of the lands of France, Spain and Great Britain was created.

However, for the colonists the war did not have favorable consequences; despite fighting for Great Britain they were not allowed to continue their expansion towards the newly conquered lands, taxes were also increased (due to the high economic cost that the war had), and a compensation for the colonists was not recognized. Therefore, later the colonists revolting against Great Britain and declaring a war of independence.
