The United States is the historical nation whose revolution forms Assassin’s Creed III’s main setting.
The game is set during the American Revolution, primarily between 1754 and 1783, and follows Ratonhnhaké:ton, commonly called Connor. Connor is a Kanien'kehá:ka man who becomes involved with the Assassin Brotherhood while seeking to protect his community and oppose Templar influence. His story intersects with figures including George Washington, Benjamin Franklin, and Charles Lee.
Major playable locations include Boston, New York, and the Frontier. The Frontier is a large wilderness area rather than a separate country, and the game also includes naval sequences along the Atlantic coast. Historical events are adapted for the fictional Assassin–Templar conflict, so the game is not a documentary account of the revolution.
The title’s modern political context is the formation of the United States, although the colonies were still British before independence was secured. That distinction explains why “United States” identifies the game’s national setting while “British America” describes much of the colonial context.
