Which historical event forms the setting of Assassin's Creed Unity?

The French Revolution forms the historical setting of Assassin's Creed Unity.

Released in 2014, Assassin's Creed Unity follows Arno Dorian in Paris during the period of the French Revolution. The game begins in 1789, when political unrest and social upheaval intensify across France.

Arno becomes an Assassin and investigates a conspiracy connected to the death of his adoptive father. The story includes real figures and events associated with revolutionary Paris, while its fictional characters operate within the historical backdrop.

Unity is distinct from Assassin's Creed III, which is set mainly during the American Revolution. It is also separate from Assassin's Creed Rogue, whose story overlaps the mid-eighteenth-century conflict in North America. Unity's cooperative missions allow multiple players to take part in selected activities as Assassins.
