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 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.
Roman rule had ceased by 508, when Clovis the Frank made the city the capital of the Merovingian dynasty of the Franks. Viking invasions during the 800s forced the Parisians to build a fortress on the Ile de la Cité. On March 28, 845 Paris was sacked by Viking raiders, probably under Ragnar Lodbrok, who collected a huge ransom in exchange for leaving.
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.
Paris held out for four months, by which time starvation had taken hold and the population had been reduced to eating rats. The city finally surrendered on 28 January 1871 with punitive terms being inflicted on the defeated French. They were, in fact, unacceptably punitive in the eyes of many Parisians, who saw the peace treaty signed by the government of Adolphe Thiers as a betrayal.
The city emerged into an energetic but restless interwar period, enlivened by the arrival of glamorous émigrés such as Josephine Baker. It was a troubled political period, however, especially when the Great Depression hit Paris.
The election of François Mitterrand in 1981 saw further major changes to the city's appearance and politics. The socialist Mitterrand frequently clashed with the powerful and abrasive Jacques Chirac, mayor of the city since 1977. Mitterrand undertook a number of grandiose grands projets to stamp his mark on the city.
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.
After the restoration of civilian rule and the proclamation of the Fourth Republic in 1946, Paris made a rapid recovery from the war, aided by its lack of much physical damage. Like the rest of France, however, it was caught up in the bloody but unsuccessful wars against nationalist guerrillas in Indochina and Algeria in the 1950s and 1960s. During the Algerian war of independence, independentists detonated bombs in Paris.
