In Assassin's Creed III, which historical event does the opening sequence portray in Boston?

In Assassin's Creed III, the opening sequence portrays the Boston Massacre.

The event occurred on March 5, 1770, when British soldiers fired on a crowd in Boston, killing five colonists. In the game, the sequence is presented through the perspective of the Templar character Haytham Kenway during the opening chapters.

The historical incident became important propaganda for the American revolutionary cause. Paul Revere's famous engraving, based partly on an earlier design by Henry Pelham, helped shape the event's public image even though it simplified the circumstances.

The Boston Massacre is often mixed up with the Boston Tea Party, which occurred in 1773, three years later. Assassin's Creed III also depicts other Revolutionary-era events, but its opening Boston historical sequence specifically centers on the 1770 shooting.
