How did British attempt to reform the American Empire contribute to the growth of the Revolutionary movement?

In the immediate aftermath the French and Indian War, which resulted in massive territorial gains but also enormous expense for the British government, the British determined to maintain tighter control over the colonies. This involved significant alterations in the colonial relationship. First, the British attempted to regulate trade more tightly through the Sugar Act of 1764. This angered many colonists, especially merchants that had become quite wealthy through violating the requirements of the old Navigation Acts (essentially acting as smugglers in the process). Second, the British attempted to tighten control of the territorial expansion of the colonies by establishing a barrier at the Appalachian Mountains with the Proclamation of 1763. This upset many colonists, from ordinary settlers to influential land speculators. Finally, Parliament, seeking to recoup some of the expense of the French and Indian War, passed the Stamp Act in 1765. This was a direct tax on the colonists, and marked a significant change in the relationship between the colonies and the mother country, one which angered almost everyone and sparked such vehement and violent protest that it was repealed a little over a year later. These three reforms in the immediate aftermath of the French and Indian War were aimed at exerting more power over the colonies. They would prove a disastrous failure.
