The French Revolution effectively began in Paris, which the king had garrisoned with foreign troops to quell any unrest. On 13 July 1789 a hitherto unknown lawyer named Camille Desmoulins sparked the revolt when he jumped on a café table in the Palais-Royal and denounced Louis XVI's dismissal of his minister, Jacques Necker, who was widely seen as the only honest man in the government. Desmoulins ended his speech with the call "Aux armes!" ("To arms!").
His grandson Louis IX, renowned for his extreme piety (and later canonised as St Louis) established the city as a major centre of pilgrimage in the 13th century with the construction of the cathedral of Notre Dame de Paris, the Basilica of St Denis and the Sainte-Chapelle on the Ile de la Cité. The latter was one of the finest medieval Gothic religious buildings ever constructed and was built to house Louis' most precious possession - the (alleged) Crown of Thorns, purchased from the bankrupt Byzantine Empire at an extortionate price.
Under Louis XVI, Paris reached new heights of prestige as a centre of the arts, sciences and philosophy. It was in Paris that the Montgolfier brothers made their historic balloon ascents in 1783. However, the French state was by now virtually bankrupt, its finances drained by the Seven Years' War and the French intervention in the American War of Independence.
As early as the 12th century, the distinctive character of the city's districts was emerging. The Ile de la Cité, on which the Cathedral of Notre Dame de Paris was built in 1163, was the centre of government and religious life; the Left Bank was the centre of learning, focusing on the various Church-run schools established there; and the Right Bank was the centre of commerce and finance. A league of merchants, the so-called Hanse Parisienne, was established and quickly became a powerful force in the city's affairs.
An invading Prussian army heading for Paris was defeated shortly afterwards, clearing the way for the bloodiest phase of the Revolution. A guillotine was erected in what is now the Place de la Concorde and was used on 21 January 1793 to execute Louis XVI. Marie Antoinette followed in October 1793.
Prior to 1968, département 75 was the Seine département, which contained the city of Paris and its immediate suburbs. The splitting up of the Seine département resulted in the creation of four new départements: Paris proper (75), and three départements (Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne) forming a ring around Paris, often called la petite couronne (i.e. the "small ring", as opposed to the "large ring" of the more distant suburbs of Paris).
The following day, 14 July the mob seized the arsenal at the Invalides, acquiring thousands of guns, and stormed the Bastille. A brief battle ensued in which 87 revolutionaries were killed before the fortress surrendered. This event marked the first real manifestation of the Revolution, and is still marked in France as Bastille Day.
In 1900 Paris hosted the 1900 Summer Olympics. In late August 1944 after the battle of Normandy, Paris was liberated when the German general Dietrich von Choltitz surrendered after skirmishes to the French 2nd Armoured Division commanded by Philippe de Hauteclocque backed by the Allies.
A revolt broke out on 18 March when government forces were driven out of Montmartre. The government regrouped at Versailles, while on 26 March the Commune of Paris - effectively a miniature socialist republic - was proclaimed in the city.
His great-grandson Louis XV became king at the age of only five, with Philip of Orleans serving as regent. The Court returned to Paris, with the new king installed in the Palais-Royal. Philip quickly gained a reputation for corruption and debauchery. His involvement in the financial scandal of the South Sea Bubble in 1720 greatly discredited him, freeing Louis XV to move the court back to Versailles.
When Hitler invaded France on 14 May 1940 it took the German army only a month to reach Paris, invading through neutral Belgium around the Maginot Line, where the French defenses were massed. Paris fell with virtually no resistance on 14 June. Much of the city's population fled, with 1.6 million of its 3.5 million people leaving between May and June 1940.
At the same time, Paris acquired a less savoury reputation as the "sin capital of Europe", with hundreds of brothels, revues and risqué cabarets such as the famous Moulin Rouge. The city also acquired its metro system, opened in 1900.
The city was neglected by the Empire and suffered grievously from Viking raiders who repeatedly sailed upriver to attack it. On March 28, 845 Paris was sacked by Viking raiders, probably under Ragnar Lodbrok, who collected a huge ransom in exchange for leaving. The weakness of the late Carolingian kings led to the gradual rise in power of the Counts of Paris.
Paris' party continued virtually until the eve of the outbreak of the First World War on 2 August 1914. Like other French cities, Paris initially welcomed the war as an opportunity to gain revenge for the defeat of 1870. Within a month, however, the city was full of refugees and the Germans were just 15 miles from the city. The government was evacuated to Bordeaux in the expectation that Paris would again fall to German forces.
