This video is really good to watch if you are studying about American Revolution. This video is about the Boston Tea Party which happened in 16th December 1773.
The Boston Tea Party is referred to "the destruction of the tea." It's the reaction from the tea tax. The Sons of Liberty disguised as Mohawk Indians, then they threw the King's tea boxes into the sea.The colonies didn't expect England to react so strongly. England isolated Boston and takes it as threat to British rule.
The Boston Tea Party is actually held quietly, unlike the video. The men that were disguised as Mohawk Indians threw the tea boxes into the sea as the town people gathered around to watch them.
