In Assassin's Creed Unity, which major 18th-century revolution forms the game's historical backdrop?

In Assassin's Creed Unity, the French Revolution forms the game's historical backdrop.

Unity follows Arno Dorian in Paris during the late 18th century. The story begins before the revolution's most dramatic events and continues through a period of political upheaval, violence, and changing power. Arno's personal search for answers becomes entangled with Assassin and Templar activity.

The game recreates recognizable Parisian locations and references historical figures and events, including the storming of the Bastille and the rise of revolutionary factions. Its characters and secret conflict are fictionalized, so the game should be read as historical fiction rather than a documentary account.

The American Revolution is the setting of Assassin's Creed III, and the Russian Revolution appears in other franchise stories and media. Unity is specifically identified with the French Revolution and revolutionary Paris.
