Paris is the primary historical setting of Assassin's Creed Unity.
The game takes place during the French Revolution, beginning in 1789 and continuing through the upheavals that followed. Players control Arno Dorian, who becomes an Assassin and investigates a Templar conspiracy amid political violence and social change.
Paris is represented through landmarks and districts, including Notre-Dame, the Tuileries, and the Bastille area. The dense city supports Unity's emphasis on vertical movement, crowds, interiors, and cooperative missions.
Assassin's Creed games use several European capitals, which can cause setting mix-ups. Syndicate is centered on London during the Industrial Revolution, while Brotherhood focuses on Rome during the Italian Renaissance. Unity's defining city and historical backdrop are Paris and the French Revolution.
