The arrival in Paris of the Industrial Revolution prompted the city's breakneck growth, with migrant workers arriving from the countryside on newly-constructed railway lines. By now its population was over 900,000 people, making it one of the largest cities in Europe and far surpassing any other city in France (the next largest, Lyon and Marseille, had only about 115,000 each).
Lutetia was a prosperous place and occupied a very strategic position on the river, controlling shipping in both directions. It came under Roman control after the revolt of 52 BC when Vercingetorix led a Celtic uprising against the Romans under Caesar.
The French Revolution began with the storming of the Bastille on July 14, 1789. Many of the conflicts in the next few years were between Paris and the outlying rural areas.
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.
Louis' reign saw major changes to the face of Paris; his mother commissioned the Palais du Luxembourg, while Cardinal Richelieu built the Palais Royal and rebuilt the Sorbonne. He also commissioned a number of major Baroque churches as a statement of the Catholic Counter-Reformation.
With the recapture of the city, the Valois monarchs and French nobility sought to impose their authority on the city through the construction of various grandiose ecclesiastical and secular monuments, including churches and mansions. Over the following century the city's population more than tripled. Francois I had probably the greatest impact of any Valois monarch, transforming the Louvre and establishing a glittering court including such notables as Leonardo da Vinci and Benvenuto Cellini.
The powers of the monarchy were in theory confined by a Charter of Liberties but in practice both Louis and Charles ran an authoritarian regime reliant on Church support. On 25 July 1830 Charles issued the repressive Ordinances of St-Cloud, abolishing the freedom of the press, dissolving the Chamber of Deputies and restricting voting rights to the landed gentry only.
The government agreed an armistice with the invaders and moved south to Vichy, while Paris remained - along with two thirds of France - under German occupation. Hitler himself arrived on 23 June to inspect his latest conquest and, in a famous piece of film footage, seem to dance a triumphant jig below the Eiffel Tower (this effective piece of Allied propaganda was created by film maker John Grierson, who looped a few frames of Hitler stomping his foot once in delight, making the dictator appear to dance).
Louis and those who supported an agreement with the monarchy were accused by the radical Jacobins of being the stooges of foreign powers, and on 10 August 1792 a mob demanded that the National Assembly depose the king. When the demand was refused, the mob attacked the Tuilleries and seized the royal family. Power now passed to the radical Commune de Paris, led by Georges Danton, Marat and Robespierre.
Under Louis XVI, Paris reached new heights of prestige as a centre of the arts, sciences and philosophy. It was in Paris that the Montgolfier brothers made their historic balloon ascents in 1783. However, the French state was by now virtually bankrupt, its finances drained by the Seven Years' War and the French intervention in the American War of Independence.
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".
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.
