The siege of Belgrade was a successful attempt by Austrian troops under the command of Prince Eugene of Savoy to capture the strategically important city of Belgrade from the Ottoman Empire. It took place during the Seventh Ottoman–Venetian War (1714–1718), barely a year after the Austrian victory at the Battle of Petrovaradin (Peterwardein). The Austrians routed the Ottoman relief army under Grand Vizier Hacı Halil Pasha on 16 August. As a consequence, the Belgrade garrison, deprived of relief, surrendered to the Austrians on 21 August. The Ottoman Sultan Ahmed III sued for peace, resulting in the Treaty of Passarowitz a year later, which completed the transfer of the remainder of Hungary, the Banat and the city of Belgrade into Austrian hands.

The Belgrade Fortress (Serbian Cyrillic: Београдска тврђава, romanized: Beogradska tvrđava), consists of the old citadel (Upper and Lower Town) and Kalemegdan Park (Large and Little Kalemegdan) on the confluence of the Sava and Danube rivers, in an urban area of modern Belgrade, Serbia. Located in Belgrade's municipality of Stari Grad, the fortress costitutes the specific historical core of the city. As one of the most important representatives of Belgrade's cultural heritage, it was originally protected right after World War II, among the first officially declared cultural monuments in Serbia. The fortress was declared a Monument of Culture of Exceptional Importance in 1979, and is protected by the Republic of Serbia. It is the most visited tourist attraction in Belgrade, with Skadarlija being the second. Since the admission is free, it is estimated that the total number of visitors (foreign, domestic, citizens of Belgrade) is over 2 million yearly.

The Sava (; Slovene pronunciation: [ˈsàːʋa], Serbo-Croatian pronunciation: [sǎːʋa]; Serbian Cyrillic: Сава, Hungarian: Száva) is a river in Central and Southeast Europe, a right-bank and the longest tributary of the Danube. It flows through Slovenia, Croatia and along its border with Bosnia and Herzegovina, and finally through Serbia, feeding into the Danube in its capital, Belgrade. The Sava forms the main northern limit of the Balkan Peninsula, and the southern edge of the Pannonian Plain. The Sava is 990 kilometres (615 miles) long, including the 45-kilometre (28 mi) Sava Dolinka headwater rising in Zelenci, Slovenia. It is the largest tributary of the Danube by volume of water, and second-largest after the Tisza in terms of catchment area (97,713 square kilometres (37,727 square miles)) and length. It drains a significant portion of the Dinaric Alps region, through the major tributaries of Drina, Bosna, Kupa, Una, Vrbas, Lonja, Kolubara, Bosut and Krka. The Sava is one of the longest rivers in Europe and among the longest tributaries of another river. The population in the Sava River basin is estimated at 8,176,000, and is shared by three capital cities: Ljubljana, Zagreb and Belgrade. The Sava is about 2⁄3-navigable for larger vessels: from the confluence of the Kupa in Sisak a few kilometers below Zagreb. The name is believed to be derived from the Proto-Indo-European root *sewh1 ('to take liquid', whence the English word sup) and the ending *eh2, so that it literally means 'that which waters [the ground]'. The ancient Greeks called it Saos (Ancient Greek: Σάος).
