In Assassin's Creed III, which historical event opens the Boston Massacre sequence?

The Boston Massacre opens the historical sequence featuring young Haytham Kenway in Assassin's Creed III.

The event occurred on March 5, 1770, when British soldiers fired on civilians in Boston, killing five people. The game uses the incident as an early dramatic setting before shifting its focus to Haytham's son, Ratonhnhaké:ton, also known as Connor.

Assassin's Creed III is set during the American Revolution and presents both fictional characters and real historical figures. The Boston Massacre was a key piece of Patriot propaganda, although historians describe the confrontation in the context of escalating tension between residents and British troops.

The Boston Tea Party is another major event depicted later in the game, which makes the two episodes easy to confuse. The opening historical sequence is specifically tied to the Boston Massacre.
