The city of Paris is itself a département of France (Paris, 75), part of the Ile-de-France région. Paris is divided into twenty numerically arranged districts, the arrondissements. These districts are numbered in a spiral pattern with the 1er arrondissement at the center of the city.
During the 11th century the city spread to the Right Bank. In the 12th and 13th centuries, which included the reign of Philip II Augustus (1180-1223), the city grew strongly. Main thoroughfares were paved, the first Louvre was built as a fortress, and several churches, including the Cathedral of Notre-Dame, were constructed or begun.
The persecution of Jews in Paris began within 48 hours of the city's fall, when they were required to register with police. On 14 May 1941 the Vichy police began deporting Parisian Jews, rounding them up at the Velodrome d'Hiver.
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).
Henri III had nominated Henri of Navarre, a Protestant, as his heir. The new king, Henri IV, converted to Catholicism in 1594 with the declaration that "Paris is well worth a mass," thus convincing the Parisians to accept him as their king. He undertook a number of major public works in the city but faced constant danger from religious fanatics on both sides, particularly after granting religious tolerance to Protestants under the Edict of Nantes. After surviving at least 23 assassination attempts, he fell victim to a Catholic fanatic on 14 May 1610.
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 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.
Administratively speaking, the public transportation networks of the Paris region are coordinated by the Syndicat des transports d'Île-de-France (STIF), formerly Syndicat des transports parisiens (STP). official site (http://www.stif-idf.fr/) Members of the syndicate include the RATP, which operates the Parisian and some suburban busses, the Métro, and sections of the RER; the SNCF, which operates the rest of the RER and the suburban train lines; and other operators.
When Hitler invaded France on 14 May 1940 it took the German army only a month to reach Paris, invading through neutral Belgium around the Maginot Line, where the French defenses were massed. Paris fell with virtually no resistance on 14 June. Much of the city's population fled, with 1.6 million of its 3.5 million people leaving between May and June 1940.
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 inhabitants of Paris are known as Parisians in English, as Parisiens in French, and as Parigots in French slang.
Royalist France achieved its greatest heights under Louis XIV, the "Sun King." His minister of finance Jean-Baptiste Colbert undertook lavish building projects in Paris in an effort to make it a "new Rome" fit for the Sun King. The king himself, however, detested Paris, preferring instead to rule France from his vast chateau at Versailles. The city had by this time grown far beyond its medieval boundaries, with some 500,000 inhabitants and 25,000 houses by the mid-17th century.
