The Boston Tea Party was an American political and mercantile protest on December 16, 1773, by the Sons of Liberty in Boston in colonial Massachusetts. The target was the Tea Act of May 10, 1773, which allowed the East India Company to sell tea from China in American colonies without paying taxes apart from those imposed by the Townshend Acts. The Sons of Liberty strongly opposed the taxes in the Townshend Act as a violation of their rights. In response, the Sons of Liberty, some disguised as Native Americans, destroyed an entire shipment of tea sent by the East India Company.
