In Assassin's Creed Unity, which historical event opens the game's main story in 1789?

The French Revolution opens the main historical story of Assassin's Creed Unity in 1789.

The game follows Arno Dorian, who becomes involved with the Parisian Assassin Brotherhood during a period of political upheaval. The opening sequence takes place at the Palace of Versailles before the story moves into revolutionary Paris.

The French Revolution began in 1789 and brought the fall of the Bastille, the abolition of feudal privileges, the establishment of a republic, and years of conflict. Unity uses real events and figures as the backdrop for Arno's fictional personal story.

The game should not be confused with Assassin's Creed III, whose historical storyline is set mainly during the American Revolution. Unity's Paris setting, crowds, and changing districts are designed around revolutionary France.
