Extreme right- and left-wing parties flourished, and on 5 February 1934 a mob of Fascist and other far-rightists attempted to storm the National Assembly in a botched coup attempt. In the ensuing violence, fifteen people were killed and another 1,500 wounded. In response, the Socialists and Communists united to form a Popular Front, which took power in 1936 but fell only a year later.
Civil war broke out in France after the assassination of Louis of Valois, Duke of Orléans by the Burgundian John the Fearless. In the ensuing chaos, the English captured Paris in 1420. In 1422, Henry V of England died at the Chateau de Vincennes, just outside the city.
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.
His grandson Louis IX, renowned for his extreme piety (and later canonised as St Louis) established the city as a major centre of pilgrimage in the 13th century with the construction of the cathedral of Notre Dame de Paris, the Basilica of St Denis and the Sainte-Chapelle on the Ile de la Cité. The latter was one of the finest medieval Gothic religious buildings ever constructed and was built to house Louis' most precious possession - the (alleged) Crown of Thorns, purchased from the bankrupt Byzantine Empire at an extortionate price.
His great-grandson Louis XV became king at the age of only five, with Philip of Orleans serving as regent. The Court returned to Paris, with the new king installed in the Palais-Royal. Philip quickly gained a reputation for corruption and debauchery. His involvement in the financial scandal of the South Sea Bubble in 1720 greatly discredited him, freeing Louis XV to move the court back to Versailles.
Prior to 1968, département 75 was the Seine département, which contained the city of Paris and its immediate suburbs. The splitting up of the Seine département resulted in the creation of four new départements: Paris proper (75), and three départements (Hauts-de-Seine, Seine-Saint-Denis and Val-de-Marne) forming a ring around Paris, often called la petite couronne (i.e. the "small ring", as opposed to the "large ring" of the more distant suburbs of Paris).
Paris became the scene of revolutionary ferment, with political clubs taking over buildings for their headquarters. The uprising had, however, badly disrupted food supplies and in October an angry crowd marched to Versailles to protest - whereupon Marie Antoinette allegedly dismissed them with her famous remark, "let them eat cake."
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.
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.
Louis died in 1643, leaving the throne to his five-year-old heir Louis XIV. The new king and his family were forced to flee the city in 1648 by a rebellion, known as the Fronde, against royal authoritarianism and excessive taxes. Rebel rule proved considerably worse, however, and the king returned to a hero's welcome in 1653.
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.
The town sided with the rebels and was said to have contributed 8,000 men to Vercingetorix's army. It was garrisoned by Vercingetorix's lieutenant Camulogenus, whose army camped on the Mons Lutetius (where the Panthéon is now situated). The Romans crushed the rebels at nearby Melun and took control of Lutetia.
It was under Napoleon's rule that Paris in its modern form was created. In 1853 he appointed Baron Haussmann as Prefect, charged with modernising the city. This Haussmann did to a drastic extent, demolishing much of the old city and replacing it with a network of wide, straight boulevards and radiating circuses.
