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!").
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.
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.
Louis died in 1643, leaving the throne to his five-year-old heir Louis XIV. The new king and his family were forced to flee the city in 1648 by a rebellion, known as the Fronde, against royal authoritarianism and excessive taxes. Rebel rule proved considerably worse, however, and the king returned to a hero's welcome in 1653.
Lutetia was renamed Paris in 212, after the local tribe, but the rest of the 3rd and 4th century was wracked by war and civil unrest. The city came under attack from barbarian invaders, prompting the construction of a defensive city wall. In 357 the Emperor Constantine's nephew Julian arrived in Paris to become the city's new governor. Although his uncle was famously the emperor who declared Christianity the official religion of the Empire, Julian "the Apostate" strove to roll back its advance. He became emperor in 361 but died in battle only two years later.
The discontented Parisian population was ripe for an uprising, and on 22 February 1848 it duly came when troops fired on demonstrators. Louis Philippe abdicated and was replaced by a Second Republic. Nationwide elections returned a conservative government which opposed any reforms. The Parisian workers rose again only to be massacred by General Cavaignac, with some 5,000 people being killed in the fighting and subsequent reprisals. Fresh elections were held at the end of 1848.
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.
The Merovingian kings died out in 751, to be replaced by the Carolingians. Pépin was proclaimed king of the Franks in 751, to be succeeded by Charlemagne, who moved the capital of his Holy Roman Empire from Paris to Aachen.
France's political divisions were a major factor in its ill-preparedness for the outbreak of the Second World War on 3 September 1939. Some of the Catholic Right were openly hostile to parliamentary democracy, Socialism and Communism, and welcomed the possibility of a fascist regime, even imposed by foreign forces.
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 city was saved, however, by a desperate French effort to reinforce their lines and by a German failure to press home the attack. In the most famous incident of the "miracle on the Marne", as it became known, thousands of Parisian taxis were commandeered to carry soldiers to the front lines. The Germans were pushed back to the Oise some 75 miles away from the city.
The following month, more than 2,000 people were massacred in Paris as revolutionary mobs hunted down and killed anyone seen as an opponent of the new order. The monarchy was formally abolished on 22 September 1792, "Day I of Year I of the French Republic."
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.
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.
