- The Tea Act lowered taxes on tea shipped by the British East India Company, undercutting prices of smuggled Dutch tea and angering many colonists.
- In December 1773, a group of colonists dressed as Native Americans boarded ships in Boston Harbor and threw hundreds of chests of British East India Company tea overboard, an event known as the Boston Tea Party.
- In response, Britain passed the Intolerable Acts to punish Boston and close its port, further increasing tensions between Britain and the colonies. This led the colonies to form the First Continental Congress and begin organizing militias in preparation for conflict with Britain.
