It incited a famous 18th-century "party"

TEAACT

This event involved colonists disguised as Native Americans and a shipment of leaves in Boston Harbor. Think of a two-word action that became a protest symbol.

This clue refers to the Boston Tea Party, the 18th-century protest where American colonists dumped tea into the harbor. The answer "TEAACT" combines "TEA" (the drink at the center of the event) with "ACT" (the action of protesting). It’s a clever way to hint at the historical incident while playing with the words involved.
