Which event that occurred between 1763 and 1776 was the most significant cause of the American Revolution?

In 1763, Britain was in debt as a result of the Seven Year's War. In an attempt to pay this, and obtain more money for troops, the Crown imposed on the 13 colonies a series of laws and taxes.

People resented and rejected them actively, through protests and riots, because they thought that was just the introduction to worse, more controlling policies in the future, and they weren't willing to let that happen.

Some of the Acts were:

The Sugar Act (1764) The Currency Act (1764) The Stamp Act (1765) The Townshend Act (1767) The Tea Act (1773) The Coercive or Intolerable Acts (1774)
