Matters came to a head on 23 August 1572 with the St Bartholomew's Day Massacre, when Catholic mobs killed an estimated 3,000 Protestants on the instructions of King Charles VIII. His successor, King Henry III, attempted to find a peaceful solution but the city's population turned against him and forced him to flee in May 1588. The following year, he was assassinated by a fanatical Dominican monk, bringing the Valois line to a premature end.
As early as the 12th century, the distinctive character of the city's districts was emerging. The Ile de la Cité, on which the Cathedral of Notre Dame de Paris was built in 1163, was the centre of government and religious life; the Left Bank was the centre of learning, focusing on the various Church-run schools established there; and the Right Bank was the centre of commerce and finance. A league of merchants, the so-called Hanse Parisienne, was established and quickly became a powerful force in the city's affairs.
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.
In the aftermath of the revolt, Charles V of France took steps to guard against a recurrence; a new city wall was constructed to guard against exterior enemies while the grim fortress of the Bastille was built to control the city's restless population. Another revolt, this time over excessive taxation, broke out in 1382 under Charles VI of France but was quickly and violently suppressed. The city was subsequently punished by having its earlier privileges withdrawn.
The new rulers organised themselves into a five-man Directoire but had only a shaky grip on power. In 1795 they were saved from a royalist revolt by a young army officer named Napoleon Bonaparte, who dispersed a hostile Parisian mob by the simple expedient of firing into it with cannons at point-blank range.
The government agreed an armistice with the invaders and moved south to Vichy, while Paris remained - along with two thirds of France - under German occupation. Hitler himself arrived on 23 June to inspect his latest conquest and, in a famous piece of film footage, seem to dance a triumphant jig below the Eiffel Tower (this effective piece of Allied propaganda was created by film maker John Grierson, who looped a few frames of Hitler stomping his foot once in delight, making the dictator appear to dance).
The city's status was reflected in the construction of grandiose new monuments, such as the Arc de Triomphe and the Eglise du Dome in which Napoleon's body was interred. Much of the population, however, lived in appalling conditions in diseased slums; a cholera outbreak in 1831 killed over 19,000 people.
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).
