What message did the Boston Tea Party send to the king?

The Boston Tea Party sent a clear message to King George III that American colonists would not tolerate taxation without representation. By dumping a large quantity of British tea into Boston Harbor, the colonists demonstrated their defiance against the Tea Act and British authority. This act of protest signified a growing sentiment for independence and unity among the colonies, challenging the king's control and policies. Ultimately, it escalated tensions between Britain and the colonies, paving the way for the American Revolution.
