During which historical conflict is Assassin's Creed Unity primarily set?

Assassin's Creed Unity is primarily set during the French Revolution.

The game takes place mainly in Paris beginning in 1789, the year commonly associated with the Revolution's outbreak. Its protagonist, Arno Dorian, becomes involved with the French Assassin Brotherhood while political unrest, violence, and changing power structures reshape the city.

The campaign includes recognizable historical places and events, including the storming of the Bastille and the Reign of Terror. The game uses these events as a backdrop for its fictional Assassin–Templar narrative rather than presenting a purely documentary account of the Revolution.

The American Revolution is the principal setting of Assassin's Creed III. The Napoleonic Wars occur later than the main revolutionary period, while the Hundred Years' War belongs to medieval France and England. Unity was released in 2014 and was designed for PlayStation 4, Xbox One, and Windows.
