Bird's-eye View Of Paris, France

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.
France's late 19th-century Universal Expositions made Paris an increasingly important centre of technology, trade, and tourism. Its most famous were the 1889 Exposition universelle to which Paris owes its "temporary" display of architectural engineering progess, the Eiffel Tower, a structure that remained the world's tallest building until 1930; the 1900 Universal Exposition saw the opening of the first Paris Métro line.
• 20th century
During World War I, Paris was at the forefront of the war effort, having been spared a German invasion by the French and British victory at the First Battle of the Marne in 1914. In 1918–1919, it was the scene of Allied victory parades and peace negotiations. In the inter-war period Paris was famed for its cultural and artistic communities and its nightlife. The city became a gathering place of artists from around the world, from exiled Russian composer Stravinsky and Spanish painters Picasso and Dalí to American writer Hemingway.
