Lutetia was renamed Paris in 212, after the local tribe, but the rest of the 3rd and 4th century was wracked by war and civil unrest. The city came under attack from barbarian invaders, prompting the construction of a defensive city wall. In 357 the Emperor Constantine's nephew Julian arrived in Paris to become the city's new governor. Although his uncle was famously the emperor who declared Christianity the official religion of the Empire, Julian "the Apostate" strove to roll back its advance. He became emperor in 361 but died in battle only two years later.
Henri III had nominated Henri of Navarre, a Protestant, as his heir. The new king, Henri IV, converted to Catholicism in 1594 with the declaration that "Paris is well worth a mass," thus convincing the Parisians to accept him as their king. He undertook a number of major public works in the city but faced constant danger from religious fanatics on both sides, particularly after granting religious tolerance to Protestants under the Edict of Nantes. After surviving at least 23 assassination attempts, he fell victim to a Catholic fanatic on 14 May 1610.
An invading Prussian army heading for Paris was defeated shortly afterwards, clearing the way for the bloodiest phase of the Revolution. A guillotine was erected in what is now the Place de la Concorde and was used on 21 January 1793 to execute Louis XVI. Marie Antoinette followed in October 1793.
Tensions were high, and led to the largest abuse in the city's postwar history, when the Paris police, told wrong news about policemen having been murdered by independentists, massacred an estimated 300 pro-independence demonstrators on 17 August 1961; remarkably, the event, though known in some circles, was largely ignored until the 1990s. (See Paris massacre of 1961)
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).
Greater Paris metropolitan area, with a total GDP higher than Australia, is the largest financial and business center of continental Europe (on par with London), harboring more than 30% of France's white-collar population, as well as more than 40% of the headquarters of French companies, with the largest business district of Europe (La Défense), and the 2nd largest stock exchange in Europe (Euronext).
A general uprising in Paris followed with three days of fighting between loyalists and rebels, including whole regiments of the Paris garrison. The king was forced to abdicate, being replaced by the more acceptable Louis-Philippe.
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 the rule of Philippe Auguste, who became king in 1180, a number of major building works were carried out in Paris. He built a new city wall and began the construction of the Louvre Palace, as well as paving streets and establishing a covered market at Les Halles (where it would remain until 1969).
The city of Paris also comprises two forests: the Bois de Boulogne on the west and the Bois de Vincennes on the east.
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.
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.
The city's escape from Attila proved a short-lived reprieve, as it was attacked and overrun in 464 by Childeric I (Childeric the Frank). His son Clovis I made the city his capital in 506 and was buried there on his death in 511, alongside St. Geneviéve.
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.
