Boston Tea Party:

After the repealing of the Townshend Acts, the tax on British Tea was left as a way for Britian to show that they still had some control over the colonies. Unfortunately Boston was also suffering economically, which was only further aggravated by troops taking low-paying, off duty jobs.

Because of the official boycott on British Tea, Dutch tea was being smuggled in at much cheaper prices. The merchants were suffering and tons of Tea was being left to rot. In order to ensure that the Tea got into port Britain sent troops into Boston. In December 1773, as a ship carrying British Tea came into port, the Sons of Liberty boarded and threw overboard thousands of pounds of tea into the harbor. Britain responded with the Coercive Acts, further inflaming the colonists and leading to war.
