Sons of Liberty were a groups of patriots who worked to oppose British rule before the American Revolution. Disguised as Mohawk native Americans boarded 3 ships carrying tea made by the East Indian Company and dumped tea into The Boston Harbor, on December 16, 1773. , protesting against British rule and high taxes. They were not officially justified because they acted according to their own beliefs and often did violent acts. Still, some think that what they did was an patriotic act.
