Britain shut down the Boston harbor until the East India company tea was paid for. There was 342 chest that had to be paid for until the harbor to open again.
This made the colonist angry about the new laws.So they dressed up like Native Americans as a disguise and dumped over the tea.
Then Britain's soldiers came up and found the colonist even them dressed up. After that Britain was no happy so they tried making new rules but the colonist didn't agree to that.So that's when the American Revolution comes in.
