Answer:
It depends if you're referring to the American Revolution (and an incident in Boston during which colonists refused to pay taxes on tea (which were a result of the tea act) and subsequently dumped boatloads of tea into the Boston Harbor). If you're referring to that, as your categories might suggest, then no, it was an event in American history.
If you're referring to current American politics, the answer is still no. Although "Tea Party" members would like to consider themselves part of a party, they're really more of an ultra-conservative movement.
