context_page_description: The history of Belgrade dates back to at least 7000 BC. One of the largest prehistoric cultures of Europe, the Vinča culture, evolved from the Belgrade area in the 6th millennium BC. In antiquity, Thraco-Dacians inhabited the region, and after 279 BC Celts conquered the city, naming it Singidūn. It was conquered by the Romans during the reign of Augustus, and awarded city rights in the mid 2nd century. It was settled by the Slavs in the 520s, and changed hands several times before it became the capital of King Stefan Dragutin. In 1521 Belgrade was conquered by the Ottoman Empire and became the seat of a sanjak. It frequently passed from Ottoman to Habsburg rule, which saw the destruction of most of the city during the Austro-Ottoman wars. Belgrade was again named the capital of Serbia in 1841. The north of Belgrade remained an Habsburg outpost until 1918, when it was merged into the capital city. As a strategic location, the city was battled over in 115 wars and razed to the ground 44 times. Belgrade was the capital of Yugoslavia from its creation in 1918, to its final dissolution in 2006.
context_section_description: The First World War began on 28 July 1914 when Austria-Hungary declared war on Serbia. Most of the subsequent Balkan offensives occurred near Belgrade. Austro-Hungarian monitors shelled Belgrade on 29 July 1914, and it was taken by the Austro-Hungarian Army under General Oskar Potiorek on 30 November. On 15 December, it was re-taken by Serbian troops under Marshal Radomir Putnik. After a prolonged battle which destroyed much of the city, between 6 and 9 October 1915, Belgrade fell to German and Austro-Hungarian troops commanded by Field Marshal August von Mackensen on 9 October 1915. The city was liberated by Serbian and French troops on 1 November 1918, under the command of Marshal Louis Franchet d'Espérey of France and Crown Prince Alexander of Serbia. Since Belgrade was decimated as the front-line city, Subotica overtook the title of the largest city in the Kingdom for a short while.
  After the war, Belgrade became the capital of the new Kingdom of Serbs, Croats and Slovenes, renamed the Kingdom of Yugoslavia in 1929. The Kingdom was split into banovinas, and Belgrade, together with Zemun and Pančevo, formed a separate administrative unit.
  During this period, the city experienced fast growth and significant modernisation. Belgrade's population grew to 239,000 by 1931 (incorporating the town of Zemun, formerly in Austria-Hungary), and 320,000 by 1940. The population growth rate between 1921 and 1948 averaged 4.08% a year. In 1927, Belgrade's first airport opened, and in 1929, its first radio station began broadcasting. The Pančevo Bridge, which crosses the Danube, was opened in 1935, while King Alexander Bridge over the Sava was opened in 1934. On 3 September 1939 the first Belgrade Grand Prix, the last Grand Prix motor racing race before the outbreak of World War II, was held around the Belgrade Fortress and was followed by 80,000 spectators. The winner was Tazio Nuvolari.
