The French Revolution (French: Révolution française; 1789–1799), was a period of radical social and political upheaval in France that had a major impact on France and indeed all of Europe. The absolute monarchy that had ruled France for centuries collapsed in three years. French society underwent an epic transformation, as feudal, aristocratic and religious privileges evaporated under a sustained assault from radical left-wing political groups, masses on the streets, and peasants in the countryside. Old ideas about tradition and hierarchy – of monarchy, aristocracy and religious authority – were abruptly overthrown by new Enlightenment principles of equality, citizenship and inalienable rights.

The French Revolution began in 1789 with the convocation of the Estates-General in May. The first year of the Revolution saw members of the Third Estate proclaiming the Tennis Court Oath in June, the assault on the Bastille in July, the passage of the Declaration of the Rights of Man and of the Citizen in August, and an epic march on Versailles that forced the royal court back to Paris in October. The next few years were dominated by tensions between various liberal assemblies and a right-wing monarchy intent on thwarting major reforms.
