In Assassin's Creed III, which historical event begins the game's 1775 setting?

Assassin's Creed III begins its 1775 setting during the American Revolution.

The game moves through the period when the Thirteen Colonies rebelled against British rule. Its historical backdrop includes Boston, New York, frontier regions, and major figures such as George Washington and Benjamin Franklin. The story combines this real political upheaval with the fictional Assassin–Templar conflict.

The year 1775 is significant because armed fighting between colonial forces and Britain began that year, including the battles of Lexington and Concord. The Declaration of Independence followed in 1776, so the game's opening period predates that declaration.

The Boston Tea Party occurred in 1773 and helped intensify tensions before the war. The French Revolution began in 1789, while the War of 1812 came later. These events can appear in general discussions of revolutionary history but do not identify Assassin's Creed III's opening setting.
