he 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.\nThe 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.\nA 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.\nInternally, popular sentiments radicalized the Revolution significantly, culminating in the rise of Maximilien Robespierre and the Jacobins and virtual dictatorship by the Committee of Public Safety during the Reign of Terror from 1793 until 1794 during which between 16,000 and 40,000 people were killed. After the fall of the Jacobins and the execution of Robespierre, 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.\nAfter the Napoleonic Wars and ensuing rise and fall of Napoleon's First French Empire, a restoration of absolutist monarchy was followed by two further successful smaller revolutions (1830 and 1848). This meant the 19th century and process of modern France taking shape saw France again successively governed by a similar cycle of constitutional monarchy (1830–48), fragile republic (Second Republic) (1848–1852), and empire (Second Empire) (1852–1870). The modern era has unfolded in the shadow of the French Revolution. The growth of republics and liberal democracies, the spread of secularism, the development of modern ideologies and the invention of total war all mark their birth during the Revolution.
