Bird's-eye View Of Paris, France

Paris was occupied by Russian Cossack and Kalmyk cavalry units upon Napoleon's defeat on the 31 March 1814; this was the first time in 400 years that the city had been conquered by a foreign power. The ensuing Restoration period, or the return of the monarchy under Louis XVIII (1814–1824) and Charles X, ended with the July Revolution Parisian uprising of 1830. The new 'constitutional monarchy' under Louis-Philippe ended with the 1848 "February Revolution" that led to the creation of the Second Republic.
Throughout these events, cholera epidemics in 1832 and 1849 ravaged the population of Paris; the 1832 epidemic alone claimed 20,000 of the population of 650,000.
The greatest development in Paris's history began with the Industrial Revolution creation of a network of railways that brought an unprecedented flow of migrants to the capital from the 1840s. The city's largest transformation came with the 1852 Second Empire under Napoleon III; his préfet, Baron Haussmann, levelled entire districts of Paris' narrow, winding medieval streets to create the network of wide avenues and neo-classical façades that still make up much of modern Paris; the reason for this transformation was twofold, as not only did the creation of wide boulevards beautify and sanitize the capital, it also facilitated the effectiveness of troops and artillery against any further uprisings and barricades for which Paris was so famous.
The Second Empire ended in the Franco-Prussian War (1870–1871), and a besieged Paris under heavy bombardment surrendered on 28 January 1871. The discontent of Paris' populace with the new armistice-signing government seated in Versailles resulted in the creation of the Paris Commune government, supported by an army created in large part of members of the city's former National Guard that would both continue resistance against the Prussians and oppose the army of the "Versaillais" government. The Paris Commune ended with the Semaine Sanglante ("Bloody Week"), during which roughly 20,000 "Communards" were executed before the fighting ended on 28 May 1871. The ease with which the Versaillais army overtook Paris owed much to Baron Haussmann's renovations.
