The election of François Mitterrand in 1981 saw further major changes to the city's appearance and politics. The socialist Mitterrand frequently clashed with the powerful and abrasive Jacques Chirac, mayor of the city since 1977. Mitterrand undertook a number of grandiose grands projets to stamp his mark on the city.
The Capetian line died out in 1328, leaving no male heir. Edward II of England claimed the French throne by virtue of his descent (via his mother) from Philip IV of France. This was rejected by the French barons, who supported the rival claim of Philippe of Valois (Philip VI of France). The Hundred Years' War thus began, followed swiftly by the arrival of the Black Death.
Paris was occupied by a Gallic tribe until the Romans arrived in 52 BC. The invaders referred to the previous occupants as the Parisii, but called their new city Lutetia, meaning "marshy place". About fifty years later the city had spread to the left bank of the Seine, now known as the Latin Quarter, and had been renamed "Paris".
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.
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.
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.
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 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.
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.
The city's status was reflected in the construction of grandiose new monuments, such as the Arc de Triomphe and the Eglise du Dome in which Napoleon's body was interred. Much of the population, however, lived in appalling conditions in diseased slums; a cholera outbreak in 1831 killed over 19,000 people.
Roman rule in northern Gaul effectively collapsed in the 5th century. In 451 the region was invaded by Attila the Hun, prompting fears that Paris would be attacked. According to legend, the city was saved by the piety of Sainte Geneviève and her followers, whose prayers for relief were answered when Attila's march turned away from Paris to the south. Ste Geneviève remains Paris' patron saint to this day.
