Napoleon's brief return from exile in 1815 saw him pass through Paris, en route to destiny at Waterloo on 18 June. His replacements, the restored Bourbon monarchs Louis XVIII (1814, 1815-1824) and Charles X (1824-1830), managed between them to provoke yet another revolution in Paris, confirming the saying that the Bourbons could "learn nothing and forget nothing."
At the same time, Paris acquired a less savoury reputation as the "sin capital of Europe", with hundreds of brothels, revues and risqué cabarets such as the famous Moulin Rouge. The city also acquired its metro system, opened in 1900.
In 1900 Paris hosted the 1900 Summer Olympics. In late August 1944 after the battle of Normandy, Paris was liberated when the German general Dietrich von Choltitz surrendered after skirmishes to the French 2nd Armoured Division commanded by Philippe de Hauteclocque backed by the Allies.
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 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.
Some Parisians welcomed the occupation forces and accepted their presence and their business. Most simply kept their heads down, enduring the rationing and in some cases exploiting the profitable opportunities that it brought. Some actively resisted, but faced the constant threat of torture and death at the hands of the Gestapo and the pro-Vichy Milice (militia).
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.
Paris is the capital city of France, as well as the capital of the Île-de-France région, whose territory encompasses Paris and its suburbs. The city of Paris proper is also a département, called Paris département (French: département de Paris).
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.
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).
