In 885 the city was faced with a massive Viking invasion force, said to have numbered 700 ships and 30,000 men. Its inhabitants sought the assistance of Robert the Strong, Count of Anjou, and his son Odo, Count of Paris. Odo led the defence of the city in opposition to a ten-month Viking siege in 885 and became co-ruler of the Empire with Charles the Simple. His son Hugh Capet was elected King of France (or Francia - literally the land of the Franks) in 987. He made Paris his capital and founded a long-lasting dynasty, the Capetians.
During the latter half of the 18th century, Paris became the intellectual and cultural capital of the Western world. It became a centre of the Enlightenment with its salons becoming the centre of the new thinking of the "Age of Reason." This was positively encouraged by the state, with Louis' mistress Madame de Pompadour supporting the city's intellectuals and prompting the king to construct striking new monuments.
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.
The combination of social unrest and a somewhat authoritarian, though democratic, government under de Gaulle proved explosive and in early May 1968 an uprising duly broke out, led by Parisian students and factory workers. The evenements (events) fizzled out amidst violence between police and demonstrators, but had a significant long-term effect, eventually forcing the retirement of de Gaulle and the overdue social liberalisation of the country. Many of the leaders of the May 1968 demonstrations went on to play significant roles in local and national politics.
With other European powers mobilising to crush the Revolution, which they saw as threatening their own monarchies, the political climate in Paris worsened as rumours of foreign plots and invasions took hold.
The new rulers organised themselves into a five-man Directoire but had only a shaky grip on power. In 1795 they were saved from a royalist revolt by a young army officer named Napoleon Bonaparte, who dispersed a hostile Parisian mob by the simple expedient of firing into it with cannons at point-blank range.
Known worldwide as the City of Light (la Ville Lumière), Paris has been a major tourist destination for centuries. The city is renowned for the beauty of its architecture, its urban perspectives and avenues, as well as the wealth of its museums. Built on an arc of the River Seine, it is divided into two parts: the Right Bank to the north and the smaller Left Bank to the south.
By this time, Paris was a typically crowded early medieval city with timber buildings alongside surviving Roman remains. According to the chronicler Geoffrey of Tours, it suffered a disastrous fire in 585. The city grew beyond the boundaries of the Ile, with suburbs being established on both banks of the river.
Royalist France achieved its greatest heights under Louis XIV, the "Sun King." His minister of finance Jean-Baptiste Colbert undertook lavish building projects in Paris in an effort to make it a "new Rome" fit for the Sun King. The king himself, however, detested Paris, preferring instead to rule France from his vast chateau at Versailles. The city had by this time grown far beyond its medieval boundaries, with some 500,000 inhabitants and 25,000 houses by the mid-17th century.
As running battles were fought in the streets of Paris, Hitler ordered the city's commandant, von Choltitz, to destroy the capital. Von Choltitz, however, stalled. When General Leclerc's 2nd Armoured Division arrived on the outskirts of the city, von Choltitz ordered his forces to retreat, leaving the city open and largely intact with only stragglers from the garrison and dead-end resisters from the Vichy regime left to offer resistance. De Gaulle and Leclerc entered the city to a jubilant reception, establishing a temporary military government that lasted until 1946.
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.
Napoleon's military campaigns against the British, Austrians and Russians initially met with great success but hubris, overconfidence and poor planning caused the annihilation of his army in 1813 in the depths of a Russian winter. Russian and Austrian armies invaded France in 1814 and on 31 March 1814, Paris fell to the Russians - the first time in 400 years that the city had been conquered by a foreign power.
The town sided with the rebels and was said to have contributed 8,000 men to Vercingetorix's army. It was garrisoned by Vercingetorix's lieutenant Camulogenus, whose army camped on the Mons Lutetius (where the Panthéon is now situated). The Romans crushed the rebels at nearby Melun and took control of Lutetia.
The area of modern Paris has been inhabited since at least the fourth millennium BC, although little is known about these early inhabitants. The first known permanent settlement on the site was founded about 250 BC by a Celtic tribe called the Parisii, who established a fishing village on the Seine island that was later to become the Ile de la Cité. This was known as Lutetia, a name first recorded by Julius Caesar in his Gallic Wars.
Paris' history in the 14th century was thus punctuated by outbreaks of plague, political violence and popular uprisings. In January 1357, Étienne Marcel, the Provost of Paris, led a merchants' revolt in a bid to curb the power of the monarchy and obtain privileges for the city and the Estates General, which had met for the first time in Paris in 1347. After initial concessions by the Crown, the city was retaken by royalist forces in 1358 and Marcel and his followers were killed.
