context_page_description: Vienna, Czech: Vídeň, is the national capital, largest city, and one of nine states of Austria. Vienna is Austria's most populous city, with about 1.9 million inhabitants, and its cultural, economic, and political center. It is the 6th-largest city by population within city limits in the European Union.
  Until the beginning of the 20th century, Vienna was the largest German-speaking city in the world, and before the splitting of the Austro-Hungarian Empire in World War I, the city had 2 million inhabitants. Today, it is the second-largest German-speaking city after Berlin. Vienna is host to many major international organizations, including the United Nations, OPEC and the OSCE. The city is located in the eastern part of Austria and is close to the borders of the Czech Republic, Slovakia and Hungary. These regions work together in a European Centrope border region. Along with nearby Bratislava, Vienna forms a metropolitan region with 3 million inhabitants. In 2001, the city center was designated a UNESCO World Heritage Site. In July 2017 it was moved to the list of World Heritage in Danger.
context_section_description: In 1804, during the Napoleonic Wars, Vienna became the capital of the newly-formed Austrian Empire. The city continued to play a major role in European and world politics, including hosting the Congress of Vienna in 1814/15. After the Austro-Hungarian Compromise of 1867, Vienna remained the capital of what became the Austro-Hungarian Empire. The city functioned as a center of classical music, for which the title of the First Viennese School (Haydn/Mozart/Beethoven) is sometimes applied.
  During the latter half of the 19th century, Vienna developed what had previously been the bastions and glacis into the Ringstraße, a new boulevard surrounding the historical town and a major prestige project. Former suburbs were incorporated, and the city of Vienna grew dramatically. In 1918, after World War I, Vienna became capital of the Republic of German-Austria, and then in 1919 of the First Republic of Austria.
  From the late-19th century to 1938 the city remained a center of high culture and of modernism. A world capital of music, Vienna played host to composers such as Brahms, Bruckner, Mahler and Richard Strauss. The city's cultural contributions in the first half of the 20th century included, among many, the Vienna Secession movement in art, psychoanalysis, the Second Viennese School (Schoenberg, Berg, Webern), the architecture of Adolf Loos and the philosophy of Ludwig Wittgenstein and the Vienna Circle. In 1913 Adolf Hitler, Leon Trotsky, Josip Broz Tito, Sigmund Freud and Joseph Stalin all lived within a few miles of each other in central Vienna, some of them becoming regulars at the same coffeehouses.
  Austrians came to regard Vienna as a center of socialist politics, sometimes referred to as "Red Vienna"(“Das rote Wien”). In the Austrian Civil War of 1934 Chancellor Engelbert Dollfuss sent the Austrian Army to shell civilian housing such as the Karl Marx-Hof occupied by the socialist militia.
