The Danube (/ˈdæn.juːb/ DAN-yoob; see also other names) is a river in Europe, the second-longest after the Volga in Russia. It flows through Central and Southeastern Europe, from the Black Forest of Germany south through the Danube Delta in Romania into the Black Sea. A large and historically important river, it was once a frontier of the Roman Empire. In the 21st century, it connects ten European countries, running through their territories or marking a border. Originating in Germany, the Danube flows southeast for 2,850 km (1,770 mi), passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova, and Ukraine. Among the many cities on the river are four national capitals: Vienna, Bratislava, Budapest, and Belgrade. Its drainage basin amounts to 817,000 km (315,000 sq mi) and extends into nine more countries.

The Danube's longest headstream, the Breg, rises in Furtwangen im Schwarzwald, while the river carries its name from its source confluence in the palace park in Donaueschingen onwards. Since ancient times, the Danube has been a traditional trade route in Europe. Today, 2,415 km (1,501 mi) of its total length are navigable. The Danube is linked to the North Sea via the Rhine–Main–Danube Canal, connecting the Danube at Kelheim with the Main at Bamberg. The river is also an important source of hydropower and drinking water.

Hungary is a landlocked country in Central Europe. Spanning much of the Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. Hungary lies within the drainage basin of the Danube River and is dominated by great lowland plains. It has a population of 9.6 million, consisting mostly of ethnic Hungarians (Magyars) and a significant Romani minority. Hungarian is the official language, and among the few in Europe outside the Indo-European family. Budapest is the country's capital and largest city, and the dominant cultural and economic centre.

Prior to the foundation of the Hungarian state, various peoples settled in the territory of present-day Hungary, including the Celts, Romans, Huns, Germanic peoples, Avars and Slavs. Hungarian statehood is traced to the Principality of Hungary, which was established in the late ninth century by Álmos and his son Árpád through the conquest of the Carpathian Basin. King Stephen I ascended the throne in 1000 and converted his realm to a Christian kingdom. The medieval Kingdom of Hungary was a European power, reaching its height in the Late Middle Ages.

Cluj-Napoca (/ˈkluːʒnæˌpoʊkə/ KLOOZH-na-POH-kə; Romanian: [ˈkluʒ naˈpoka] ), or simply Cluj (Hungarian: Kolozsvár [ˈkoloʒvaːr] , German: Klausenburg), is a city in northwestern Romania. It is the second-most populous city in the country and the seat of Cluj County. Geographically, it is roughly equidistant from Bucharest (445 km; 277 mi), Budapest (461 km; 286 mi) and Belgrade (483 km; 300 mi). Located in the Someșul Mic river valley, the city is considered the unofficial capital of the historical province of Transylvania. For some decades prior to the Austro-Hungarian Compromise of 1867, it was the official capital of the Grand Principality of Transylvania.

As of 2021, 286,598 inhabitants live in the city. The Cluj-Napoca metropolitan area had a population of 411,379 people, while the population of the peri-urban area is approximately 420,000. According to a 2007 estimate, the city hosted an average population of over 20,000 students and other non-residents each year from 2004 to 2007. The city spreads out from St. Michael's Church in Unirii Square, built in the 14th century and named after the Archangel Michael, Cluj's patron saint. The municipality covers an area of 179.52 square kilometres (69.31 sq mi).

A river island is any exposed landmass surrounded by river water. Properly defined, it excludes shoals between seasonally varying flows and may exclude semi-coastal islands in river deltas such as Marajó.

These islands result from changes in the course of a river. Such changes may be caused by interactions with a tributary, or by the opposing fluvial actions of deposition and/or erosion that form a natural cut and meander. Nascent vegetation-free shoals and mudflats may dissipate and shift or build up into such islands through deposition; the process may be assisted through artificial reinforcement or natural factors, such as reeds, palms, evergreen trees or willows, that act as obstacles or erosion barriers, so that water flows around them. Islands may be small or large, covering many square kilometers, examples of which are given below.

A library is a collection of books, and possibly other materials and media, that is accessible for use by its members and members of allied institutions. Libraries provide physical (hard copies) or digital (soft copies) materials, and may be a physical location, a virtual space, or both. A library's collection normally includes printed materials which can be borrowed, and usually also includes a reference section of publications which may only be utilized inside the premises. Resources such as commercial releases of films, television programmes, other video recordings, radio, music and audio recordings may be available in many formats. These include DVDs, Blu-rays, CDs, cassettes, or other applicable formats such as microform. They may also provide access to information, music or other content held on bibliographic databases. In addition, some libraries offer creation stations for makers which offer access to a 3D printing station with a 3D scanner.

Libraries can vary widely in size and may be organised and maintained by a public body such as a government, an institution (such as a school or museum), a corporation, or a private individual. In addition to providing materials, libraries also provide the services of librarians who are trained experts in finding, selecting, circulating and organising information while interpreting information needs and navigating and analysing large amounts of information with a variety of resources. The area of study is known as library and information science or studies.

A mausoleum is an external free-standing building constructed as a monument enclosing the burial chamber of a deceased person or people. A mausoleum without the person's remains is called a cenotaph. A mausoleum may be considered a type of tomb, or the tomb may be considered to be within the mausoleum.

The siege of Buda (Hungarian: Buda visszafoglalása, lit. 'Recapture of Buda') was a military engagement during the Great Turkish War, in which forces of the Holy League, led by the Habsburg Monarchy, recaptured the fortified city of Buda (now part of modern-day Budapest) from the Ottoman Empire. The siege took place between 18 June and 9 September 1686, ending nearly 150 years of Ottoman control over the former Hungarian capital.

The campaign followed the failed Ottoman siege of Vienna in 1683 and was part of a broader counteroffensive launched by the Holy League. The coalition army of up to 100,000 men besieged the city for more than two months before storming the defences. The fall of Buda marked a decisive step in the Habsburg consolidation of central Hungary, leading to the recognition of hereditary Habsburg rule by the Hungarian Diet at Pressburg in 1687.

Robert Hetzron, born Herzog (31 December 1937, Budapest – 12 August 1997, Santa Barbara, California), was a Hungarian-born linguist known for his work on the comparative study of Afro-Asiatic languages, as well as for his study of Cushitic and Ethiopian Semitic languages.
