The French Revolution (1789-1799) was a period of radical social and political upheaval in French and European history. 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 liberal political groups and the masses on the streets. Old ideas about hierarchy and tradition succumbed to new Enlightenment principles of 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 witnessed 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 conservative monarchy intent on thwarting major reforms. A republic was proclaimed in September 1792 and King Louis XVI was executed the next year.
External threats also played a dominant role in the development of the Revolution. The French Revolutionary Wars started in 1792 and ultimately featured spectacular French victories that facilitated the conquest of the Italian peninsula, the Low Countries, and most territories west of the Rhine" achievements that had defied previous French governments for centuries. Internally, popular sentiments radicalized the Revolution significantly, culminating in the brutal Reign of Terror from 1793 until 1794. After the fall of Robespierre and the Jacobins, the Directory assumed control of the French state in 1795 and held power until 1799, when it was replaced by the Consulate under Napoleon Bonaparte.
