The Merovingian kings died out in 751, to be replaced by the Carolingians. Pépin was proclaimed king of the Franks in 751, to be succeeded by Charlemagne, who moved the capital of his Holy Roman Empire from Paris to Aachen.
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.
Several schools on the Left Bank were grouped together into the Sorbonne, which counts Albertus Magnus and St. Thomas Aquinas among its early scholars. In the Middle Ages Paris prospered as a trading and intellectual nucleus, interrupted temporarily when the Black Death struck in the 14th century. Under the reign of King Louis XIV, the Sun King, from 1643 to 1715, the royal residence was moved from Paris to nearby Versailles.
Lutetia was a prosperous place and occupied a very strategic position on the river, controlling shipping in both directions. It came under Roman control after the revolt of 52 BC when Vercingetorix led a Celtic uprising against the Romans under Caesar.
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 French Revolution began with the storming of the Bastille on July 14, 1789. Many of the conflicts in the next few years were between Paris and the outlying rural areas.
During the 11th century the city spread to the Right Bank. In the 12th and 13th centuries, which included the reign of Philip II Augustus (1180-1223), the city grew strongly. Main thoroughfares were paved, the first Louvre was built as a fortress, and several churches, including the Cathedral of Notre-Dame, were constructed or begun.
Roman rule in northern Gaul effectively collapsed in the 5th century. In 451 the region was invaded by Attila the Hun, prompting fears that Paris would be attacked. According to legend, the city was saved by the piety of Sainte Geneviève and her followers, whose prayers for relief were answered when Attila's march turned away from Paris to the south. Ste Geneviève remains Paris' patron saint to this day.
The combination of social unrest and a somewhat authoritarian, though democratic, government under de Gaulle proved explosive and in early May 1968 an uprising duly broke out, led by Parisian students and factory workers. The evenements (events) fizzled out amidst violence between police and demonstrators, but had a significant long-term effect, eventually forcing the retirement of de Gaulle and the overdue social liberalisation of the country. Many of the leaders of the May 1968 demonstrations went on to play significant roles in local and national politics.
The revolutionaries became steadily more extreme, turning on the "enemy within." This included not just royalists but those accused of simply being not sufficiently revolutionary, including Danton and Camille Desmoulins. Over 1,300 people were executed in just six weeks in 1794. In the end, the extremists' bloodthirstiness destroyed their own moral standing; a group of moderates seized control in July 1794, sending Robespierre and his allies to the guillotine in a last spasm of bloodletting.
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 city was saved, however, by a desperate French effort to reinforce their lines and by a German failure to press home the attack. In the most famous incident of the "miracle on the Marne", as it became known, thousands of Parisian taxis were commandeered to carry soldiers to the front lines. The Germans were pushed back to the Oise some 75 miles away from the city.
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.
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).
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.
