The Tea Act of 1773 imposed new taxes on tea imported to the American colonies by the British East India Company, sparking protests by colonists like the Boston Tea Party. The Act gave the East India Company a monopoly on tea sales in the colonies and was one of several measures that increased colonial opposition to British rule and contributed to the start of the American Revolutionary War. Colonists objected to being taxed by the British and disliked having to buy tea from only one company.
