In Assassin's Creed Unity, which major historical event frames the story in Paris?

Assassin's Creed Unity is framed by the French Revolution in Paris.

The story begins in 1789, when political and social upheaval overturns the established order in France. Arno Dorian becomes involved with the Parisian Assassin Brotherhood after the death of his adoptive father, François de la Serre. His personal investigation unfolds alongside major revolutionary events and the struggle between rival factions.

Unity features locations and figures connected with the period, including the Bastille, the Palace of Versailles, Maximilien Robespierre, and Napoleon Bonaparte. The French Revolution is distinct from the Industrial Revolution, which provides the setting for Assassin's Creed Syndicate in 19th-century London. It is also earlier than the July Revolution of 1830 and the Paris Commune of 1871. The title “Unity” refers to the game's themes and cooperative multiplayer, not to a separate historical revolution.
