The Boston Tea Party

After creating a tea boycott, to but only smuggled tea and not British tea, things went bad. Well bad for the British anyway. It was making the worse for the financial state of the Britsh East India Company. So Parliament allowed the company to sell the tea directly to the colonies. This would make it much cheaper than the smuggled tea.
The colonists said that this wasn't right. They protested that Parliament was only trying to trick them into buying their tea and paying their taxes. So they continued buying the smuggled tea.

The night of December 16th, 1773, some patriots dressed up as indians and boarded the three ships that contained the British tea and they dumped the tea into the harbor.
This event was later on calles The Boston Tea Party.
