Paris is densely covered by a metro system, the Métro, as well as by a large number of bus lines. This interconnects with a high-speed regional network, the RER, and also the train network: commuter lines, national train lines, and the TGV (or derivatives like Thalys or Eurostar for specific destinations). There are two tangential tramway lines in the suburbs: Line T1 runs from Saint-Denis to Noisy-le-Sec, line T2 runs from La Défense to Issy. A third line along the southern orbital road is currently under construction.
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.
Algeria gained its independence in 1962 and over 700,000 French colonists and pro-French Algerians migrated to the mother country, many to Paris. In response, the government built huge new residential suburbs - the now-notorious banlieues of Paris - which rapidly gained a reputation for soulless architecture, deprivation, racial tension and crime.
The city's escape from Attila proved a short-lived reprieve, as it was attacked and overrun in 464 by Childeric I (Childeric the Frank). His son Clovis I made the city his capital in 506 and was buried there on his death in 511, alongside St. Geneviéve.
Under Roman rule, the town was thoroughly Romanised and grew considerably. It was, however, not the capital of its province, Lugdunensis Senona - that role was played by Agedincum (modern Sens, Yonne). It was Christianised in the 3rd century when St Denis became the city's first bishop. The process was not entirely peaceful - in about 250 St Denis and two companions were arrested and decapitated on the hill of Mons Mercurius, thereafter known as Mons Martis (Martyrs' Hill, now Montmartre).
The name of the city comes from the name of a Gallic tribe (parisis) inhabiting the region at the time of the Roman conquest. The historical heart of Paris is the Île de la Cité, a small island largely occupied by the huge Palais de Justice and the Cathedral of Notre Dame de Paris. It is connected with the smaller Ile Saint-Louis (another island) occupied by elegant houses built in the 17th and 18th centuries.
The next four years saw an increasingly brutal occupation regime imposed on the city. On the surface, things continued much as before - the "City of Light" was an extremely popular assignment for German forces and a favourite destination for those with time off.
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 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!").
Under Napoleon's rule, Paris became the capital of an empire and military superpower. He crowned himself Emperor in a ceremony held in Notre-Dame on 18 May 1804. Like his royal predecessors, he saw Paris as a "new Rome" and set about building public monuments befitting the capital of an empire. Some of these were conscious copies of great Roman buildings, such as the Église de la Madeleine.
Chirac also suffered problems, although he was lucky that the worst of these did not emerge until after his election as President in May 1995. He was soon embroiled in a number of corruption scandals, many dating from his period as mayor when - allegedly - corrupt "favours" for relatives and party supporters were granted.
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.
A new wall was built around Paris in 1785, this time to create a customs barrier for taxation purposes. Not surprisingly, this was a very unpopular innovation. The disastrous harvest of 1788 brought matters to a head, with widespread hunger across France and food riots in Paris.
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.
