Paris' party continued virtually until the eve of the outbreak of the First World War on 2 August 1914. Like other French cities, Paris initially welcomed the war as an opportunity to gain revenge for the defeat of 1870. Within a month, however, the city was full of refugees and the Germans were just 15 miles from the city. The government was evacuated to Bordeaux in the expectation that Paris would again fall to German forces.
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.
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.
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.
France's political divisions were a major factor in its ill-preparedness for the outbreak of the Second World War on 3 September 1939. Some of the Catholic Right were openly hostile to parliamentary democracy, Socialism and Communism, and welcomed the possibility of a fascist regime, even imposed by foreign forces.
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.
The area of modern Paris has been inhabited since at least the fourth millennium BC, although little is known about these early inhabitants. The first known permanent settlement on the site was founded about 250 BC by a Celtic tribe called the Parisii, who established a fishing village on the Seine island that was later to become the Ile de la Cité. This was known as Lutetia, a name first recorded by Julius Caesar in his Gallic Wars.
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.
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.
Napoleon's rule came to an abrupt end when he declared war on Prussia in 1870, only to be defeated and captured at Sedan. He abdicated on 4 September, with a Third Republic proclaimed that same day in Paris. On 19 September the Prussian army arrived at Paris and besieged the city. Major city landmarks were pressed into military service, with the Louvre being turned into an arms factory, the Gare d'Orleans (now the Gare d'Austerlitz) into a balloon workshop and the Gare de Lyon into a cannon foundry.
