what event in boston harbor in part sparked the american revolution

The event in Boston Harbor that partly sparked the American Revolution was the Boston Tea Party. On December 16, 1773, American colonists, many belonging to the Sons of Liberty, boarded British ships in Boston Harbor and dumped 342 chests of tea into the water as a protest against British taxation without colonial representation. This act of defiance led to severe British retaliation, including the closing of Boston Harbor under the Intolerable Acts, and helped unite the colonies in their resistance against British rule, eventually sparking the Revolutionary War.
