British close boston harbor and station troops in city

British closed Boston harbor and station troops in the city because Colonists dumped tea at the ocean to protest new taxes.

Explanation:

This event is known as the Boston Tea Party. It was a political rebellion that occurred at Griffin's Wharf in Boston. American colonists were angry at the British for imposing taxation without representation, so they dumped approximately 341 chests of tea, which were imported by the British East India Company.

It influenced the ongoing tension between Britain and America.

The British closed Boston Harbor until all chests were paid for. This measure was taken under the Intolerable Acts in 1774 and it's also considered as the main event for the Revolutionary War.
