The Boston Tea Party took place on the night of December 16, 1773. During this event, about 60 American colonists, disguised as Native Americans, boarded ships in Boston Harbor and dumped 342 chests of tea into the water as a protest against British taxation without representation and the monopoly of the East India Company. This act of defiance was a significant precursor to the American Revolution, which began a couple of years later in 1775.
