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 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-lyses, and for its many architectural gems.
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.
Louis XIII became king at the age of only eight, with political power exercised by his mother Marie de Mdicis 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.
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.
The French Crown initially controlled little more than Paris and the surrounding region, the Ile de France, but over the centuries steadily expanded its territory and power. Paris itself developed an increasing degree of importance as a royal capital, a centre of learning and an ecclesiastical centre.
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.
As running battles were fought in the streets of Paris, Hitler ordered the city's commandant, von Choltitz, to destroy the capital. Von Choltitz, however, stalled. When General Leclerc's 2nd Armoured Division arrived on the outskirts of the city, von Choltitz ordered his forces to retreat, leaving the city open and largely intact with only stragglers from the garrison and dead-end resisters from the Vichy regime left to offer resistance. De Gaulle and Leclerc entered the city to a jubilant reception, establishing a temporary military government that lasted until 1946.
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.
Fierce fighting broke out a few days later as government troops retook the city district by district. It only ended on 29 March, by which time an estimated 4,000-5,000 people on both sides had been killed. In the aftermath, another 10,000 Communards were shot, 40,000 were arrested and 5,000 were deported.
Known worldwide as the City of Light (la Ville Lumire), Paris has been a major tourist destination for centuries. The city is renowned for the beauty of its architecture, its urban perspectives and avenues, as well as the wealth of its museums. Built on an arc of the River Seine, it is divided into two parts: the Right Bank to the north and the smaller Left Bank to the south.
Less positively and very controversially, the ancient market at Les Halles was demolished and replaced with a notoriously ugly underground shopping mall, and the 209m Tour Montparnasse skyscraper was built leading to fears that Paris would become overrun with American-style skyscrapers (a move strongly resisted ever since).
The history of Paris spans over 2,000 years, during which time the city grew from a small Celtic settlement to the multicultural capital of a modern European state.
