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 city emerged into an energetic but restless interwar period, enlivened by the arrival of glamorous émigrés such as Josephine Baker. It was a troubled political period, however, especially when the Great Depression hit Paris.
The city of Paris also comprises two forests: the Bois de Boulogne on the west and the Bois de Vincennes on the east.
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 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.
The river Seine is well known for its tree-lined quais (walks along the river banks), open-air bookstalls and historic bridges that connect the Right and Left banks. Paris is also famous for its tree-lined boulevards such as the Champs-Élysées, and for its many architectural gems.
Roman rule had ceased by 508, when Clovis the Frank made the city the capital of the Merovingian dynasty of the Franks. Viking invasions during the 800s forced the Parisians to build a fortress on the Ile de la Cité. On March 28, 845 Paris was sacked by Viking raiders, probably under Ragnar Lodbrok, who collected a huge ransom in exchange for leaving.
Chirac also suffered problems, although he was lucky that the worst of these did not emerge until after his election as President in May 1995. He was soon embroiled in a number of corruption scandals, many dating from his period as mayor when - allegedly - corrupt "favours" for relatives and party supporters were granted.
Under the rule of Philippe Auguste, who became king in 1180, a number of major building works were carried out in Paris. He built a new city wall and began the construction of the Louvre Palace, as well as paving streets and establishing a covered market at Les Halles (where it would remain until 1969).
The Bois de Boulogne and the Bois de Vincennes were both transformed into large public parks. Although Haussmann was forced to resign in 1869 after financial irregularities, his scheme is largely responsible for the present-day look and layout of Paris.
A concentration camp was established in the Parisian suburb of Drancy to serve as a waystation en route to Auschwitz. Some 70,000 people passed through the camp. Contrary to later assertions by postwar French governments, the camp was run by the French authorities on behalf of the Nazis until July 1943, and the roundups were orchestrated by the Vichy French police. This was only acknowledged by the French government in 1995 and memorialised only as recently as 2001.
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.
