Which political development greatly increased tensions between the american colonies and great britain in the years just before the american revolution?

The Proclamation of 1763

Explanation:

The Proclamation of 1763 was issued by King George III after the acquisition of French territory in North America. This was a consequence of the Seven Years' War. This document made it illegal to settle west of the Appalachian Mountains, as this was considered an Indian Reserve. This law made many colonists angry. The resentment that was created amoung the colonists is considered to have been a reason for the subsequent American Revolution.
