Which historical conflict provides the main setting for Assassin's Creed Unity?

The French Revolution provides the main historical setting for Assassin's Creed Unity.

The game begins in 1789 and follows Arno Dorian through Paris during the upheaval that transformed France. Players encounter locations and events associated with the Revolution, including political factionalism, popular unrest, and the fall of the Bastille-era social order.

Unity is set primarily in Paris, unlike Assassin's Creed III, which focuses on the American Revolution. It also differs from Assassin's Creed Odyssey, whose story takes place during the Peloponnesian War in ancient Greece. Arno's personal investigation of his adoptive father's murder is interwoven with the changing political landscape, but the game is a fictional adventure rather than a complete historical reconstruction.
