The Tea Act was an Act of the Parliament of Great Britain in 1773, allowing the East India Company to ship tea to the American colonies directly from India. This made the tea much less expensive, increasing the East India Company's profits and hopefully preventing the colonists from trying to smuggle less cheap Dutch tea.

However, the colonists objected, believing the Act was a trick to make them pay tax despite their lack of representation in Parliament. Philadelphia and New York turned away the East India Company's ships, but Thomas Hutchinson, governor of Massachusetts, allowed the ships to stay in Boston Harbor; angry citizens led by Samuel Adams staged a protest known as the Boston Tea Party, dumping the tea into the sea.

The Colonial Assassins Ratonhnhaké:ton and Stephane Chapheau participated in the Boston Tea Party to undermine the Templar William Johnson, who was smuggling tea off the ships to gain money for the purchase of the Iroquois' land. The Assassins staged subsequent protests in New Jersey and Maryland.
