The Boston Tea Party was a symbolic protest by the Sons of Liberty in 1773 against the British Tea Act. Colonists boarded three ships in Boston Harbor at night and dumped all 342 chests of taxed tea from the British East India Company into the harbor over a period of three hours. This large act of destruction of private property in response to "taxation without representation" increased tensions between the colonies and Britain and was an important event leading toward the American Revolution.
