In Assassin's Creed III, which historical event begins Connor's main story in colonial America?

The Boston Massacre begins Connor's main story in colonial America in Assassin's Creed III.

The event occurred on March 5, 1770, when British soldiers fired on civilians in Boston, killing five colonists. In the game, Ratonhnhaké:ton—better known as Connor—becomes involved in a fictionalized version of the incident during the opening sequence of his colonial-era storyline.

Assassin's Creed III places Connor within the American Revolution, combining historical figures and events with the series' fictional Assassin-Templar conflict. The game later depicts locations including Boston, New York, and the frontier.

The Boston Tea Party and the Declaration of Independence also appear in the game's historical setting, but they are later events. The Boston Massacre is the specific event that starts Connor's central colonial narrative.
