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.
The original Latin name of Paris was Lutetia, known in French as Lutèce. The name was later changed into Paris, based on the name of the Gallic parisi tribe.
A general uprising in Paris followed with three days of fighting between loyalists and rebels, including whole regiments of the Paris garrison. The king was forced to abdicate, being replaced by the more acceptable Louis-Philippe.
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.
Louis XIII became king at the age of only eight, with political power exercised by his mother Marie de Médicis in the role of regent. Although Louis took over when he reached the age of majority, at 15, the real power was exercised by the brilliant but ruthless Cardinal Richelieu, who greatly expanded royal power.
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.
In March 2001, Paris voted for a left-wing mayor for the first time since 1871. Bertrand Delanoë made history not only as the first left-wing mayor for 130 years, but for the fact that he is the first openly gay man to hold such a high public position in France. His election was widely seen as a rejection by the electorate of the corruption of the Chirac era. His manifesto promised to tackle the city administration's corruption and inefficiency, as well as reducing crime and improving education - all while keeping taxation stable.
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.
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!").
In June 1944, Allied forces (including the Free French under General Charles de Gaulle) invaded Normandy. Two months later they broke through German lines and advanced rapidly across France. An uprising broke out in Paris on 19 August, led by the Resistance and the city's Police.
