The Danube ( ; ) is Europe's second-longest river after the Volga, flowing through much of Central and Southeastern Europe, from the Black Forest into the Black Sea. Its longest headstream Breg rises in Furtwangen im Schwarzwald, while the river carries its name from its source confluence in Donaueschingen onwards. The Danube was once a long-standing frontier of the Roman Empire and today is the river running through the largest number of countries in the world (10; the Nile is second with 9). Originating in Germany, the Danube flows southeast for , passing through or bordering Austria, Slovakia, Hungary, Croatia, Serbia, Romania, Bulgaria, Moldova and Ukraine before draining into the Black Sea. Its drainage basin extends into nine more countries. The largest cities on the river are Vienna, Budapest, Belgrade and Bratislava, all of which are the capitals of their respective countries. Six more capital cities lie in the Danube's basin: Bucharest, Sofia, Zagreb, Ljubljana, Sarajevo and Pristina. The fourth-largest city in its basin is Munich, the capital of Bavaria, standing on the Isar River. The Danube river basin is home to fish species such as pike, zander, huchen, Wels catfish, burbot and tench. It is also home to a large diversity of carp and sturgeon, as well as salmon and trout. A few species of euryhaline fish, such as European seabass, mullet, and eel, inhabit the Danube Delta and the lower portion of the river. Since ancient times, the Danube has been a traditional trade route in Europe. Today, 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.

Names and etymology

''Danube'' is an Old European river name derived from a Proto-Indo-European . Other European river names from the same root include the Dunaj, Dzvina/Daugava, Don, Donets, Dnieper, Dniestr, Dysna and Tana/Deatnu. In Rigvedic Sanskrit, ''dānu'' means "fluid, dewdrop" and ''dānuja'' means "born from ''dānu''" or "born from dew-drops". In Avestan, the same word means "river". In the Rigveda, ''Dānu'' once appears as the mother of Vrtra, "a dragon blocking the course of the rivers". The Finnish word for Danube is , which is most likely derived from the word for the river in German, . Its Sámi name means "Great River". It is possible that in Scythian as in Avestan was a generic word for "river": ''Dnieper'' and ''Dniestr'', from ''Danapris'' and ''Danastius'', are presumed to continue Scythian "far river" and "near river", respectively.. The river was known to the ancient Greeks as the () a borrowing from a Daco-Thracian name meaning 'strong, swift', from a root possibly also encountered in the ancient name of the Dniester ( in Latin, in Greek) and akin to Iranic 'swift' and Sanskrit () 'swift', from the PIE , 'to flow'. In the Middle Ages, the Greek was borrowed into Italian as and into Turkic languages as , the latter further borrowed into Romanian as a regionalism (). The Thraco-Phrygian name was , "the bringer of luck". In Latin, the Danube was variously known as , , or ''Hister''. The Latin name is masculine, as are all its Slavic names, except Slovenian (the name of the Rhine is also masculine in Latin, most of the Slavic languages, as well as in German). The German (Early Modern German , , Middle High German ) is feminine, as it has been re-interpreted as containing the suffix ''-ouwe'' "wetland". Romanian differs from other surrounding languages in designating the river with a feminine term, . This form was not inherited from Latin, although Romanian is a Romance language. To explain the loss of the Latin name, scholars who suppose that Romanian developed near the large river propose that the Romanian name descends from a hypothetical Thracian . The Proto-Indoeuropean root of this presumed name is related to the Iranic word ""/"", while the supposed suffix is encountered in the ancient name of the Ialomița River, ''Naparis'', and in the unidentified ''Miliare'' river mentioned by Jordanes in his Getica. Gábor Vékony says that this hypothesis is not plausible, because the Greeks borrowed the ''Istros'' form from the native Thracians. He proposes that the Romanian name is loanword from a Turkic language (Cuman or Pecheneg). The Middle Mongolian name for the Danube was transliterated as ''Tho-na'' in 1829 by Jean-Pierre Abel-Rémusat. The modern languages spoken in the Danube basin all use names related to : german: link=no|Donau (); ; ; ; cz|Dunaj (); sk|Dunaj (); pl|Dunaj (); hu|Duna (); sl|Donava (); sh|Dunav / (); ro|Dunărea (); bg|Дунав|Dunav (); russian: Дунай|Dunaj (); uk|Дунай|Dunaj (); gr|Δούναβης (); it|Danubio (); es|Danubio; (); ; rm|Danubi; sq|Tunë, .

Classified as an [[international waterway]], it [[Source of the Danube|originates]] in the town of [[Donaueschingen]], in the [[Black Forest]] of [[Germany]], at the [[confluence]] of the rivers [[Brigach]] and [[Breg (river)|Breg]]. The Danube then flows southeast for about , passing through four capital cities (Vienna, Bratislava, Budapest, and Belgrade) before emptying into the Black Sea via the Danube Delta in Romania and Ukraine. Once a long-standing frontier of the Roman Empire, the river passes through or touches the borders of 10 countries: Romania (29.0% of basin area), Hungary (11.6%), Serbia (10.2%), Austria (10.0%), Germany (7.0%), Bulgaria (5.9%), Slovakia (5.9%), Croatia (4.4%), Ukraine (3.8%), and Moldova (1.6%). Its drainage basin extends into nine more (ten if Kosovo is included).

Drainage basin

In addition to the bordering countries (see above), the drainage basin includes parts of nine more countries: Bosnia and Herzegovina (4.6% of the basin area), the Czech Republic (2.9%), Slovenia (2.0%), Montenegro (0.9%), Switzerland (0.2%), Italy (<0.1%), Poland (<0.1%), North Macedonia (<0.1%) and Albania (<0.1%). The total drainage basin is in area and is home to 83 million people.Danube River Basin District, Part A – Roof Report
IPCDR, p 8
The highest point of the drainage basin is the summit of ''Piz Bernina'' at the Italy–Switzerland border, at . The Danube River Basin is divided into three main parts, separated by "gates" where the river is forced to cut through mountainous sections: * Upper Basin, from the headwaters to the Devín Gate. * Middle Basin, usually called the Pannonian basin or Carpathian Basin, between the Devín Gate and the Iron Gates. It includes the Hungarian plains Kisalföld and Alföld. * Lower Basin, from the Iron Gates to the river mouth, including the Danube Delta.

Tributaries

The land drained by the Danube extends into many other countries. Many Danubian tributaries are important rivers in their own right, navigable by barges and other shallow-draught boats. From its source to its outlet into the Black Sea, its main tributaries are (as they enter):

Cities and towns

The Danube flows through many cities, including four national capitals (shown below in bold), more than any other river in the world.

Modern navigation

The Danube is navigable by ocean ships from the Black Sea to Brăila in Romania (the maritime river sector), and further on by river ships to Kelheim, Bavaria, Germany; smaller craft can navigate further upstream to Ulm, Württemberg, Germany. About 60 of its tributaries are also navigable. Since the completion of the German Rhine–Main–Danube Canal in 1992, the river has been part of a trans-European waterway from Rotterdam on the North Sea to Sulina on the Black Sea, a distance of . In 1994 the Danube was declared one of ten Pan-European transport corridors, routes in Central and Eastern Europe that required major investment over the following ten to fifteen years. The amount of goods transported on the Danube increased to about 100 million tons in 1987. In 1999, transport on the river was made difficult by the NATO bombing of three bridges in Serbia during the Kosovo War. Clearance of the resulting debris was completed in 2002, and a temporary pontoon bridge that hampered navigation was removed in 2005. At the Iron Gate, the Danube flows through a gorge that forms part of the boundary between Serbia and Romania; it contains the Iron Gate I Hydroelectric Power Station dam, followed at about downstream (outside the gorge) by the Iron Gate II Hydroelectric Power Station. On 13 April 2006, a record peak discharge at Iron Gate Dam reached . There are three artificial waterways built on the Danube: the Danube-Tisa-Danube Canal (DTD) in the Banat and Bačka regions (Vojvodina, northern province of Serbia); the Danube-Black Sea Canal, between Cernavodă and Constanța (Romania) finished in 1984, shortens the distance to the Black Sea by ; the Rhine–Main–Danube Canal is about , finished in 1992, linking the North Sea to the Black Sea.

Piracy

In 2010–12, shipping companies (especially from Ukraine) claimed that their vessels suffered from "regular pirate attacks", on the Serbian and Romanian stretches of the Danube. However, these transgressions may not be considered acts of piracy, as defined according to the United Nations Convention on the Law of the Sea, but rather instances of "river robbery". On the other hand, media reports say the crews on transport ships often steal and sell their own cargo and then blame the plundering on "pirates", and the alleged attacks are not piracy but small-time contraband theft that is taking place along the river. The trading practices were legal along the river, since Romania and Bulgaria joined the EU in 2007 and Romania became European border with Ukraine and Serbia. "Vamesi" the Romanian Border Officers, were confused with the new trading rules and new borders along the river as long as most of the southern Danube border is shared with Bulgaria.

Danube Delta

The Danube Delta ( ro|Delta Dunării ; uk|Дельта Дунаю|translit=Del'ta Dunayu) is the largest river delta in the European Union. The greater part of the Danube Delta lies in Romania (Tulcea county), while its northern part, on the left bank of the Chilia arm, is situated in Ukraine (Odessa Oblast). The approximate surface is , of which are in Romania. If one includes the lagoons of Razim-Sinoe ( of which water surface), which are located south of the delta proper, but are related to it geologically and ecologically (their combined territory is part of the World Heritage Site), the total area of the Danube Delta reaches . The Danube Delta is also the best preserved river Delta in Europe, a UNESCO World Heritage Site (since 1991) and a Ramsar Site. Its lakes and marshes support 45 freshwater fish species. Its wetlands support vast flocks of migratory birds of over 300 species, including the endangered pygmy cormorant (''Phalacrocorax pygmaeus''). These are threatened by rival canalization and drainage schemes such as the Bystroye Canal.

International cooperation



Ecology and environment

The International Commission for the Protection of the Danube River (ICPDR) is an organization which consists of 14 member states (Germany, Austria, the Czech Republic, Slovakia, Slovenia, Hungary, Croatia, Bosnia and Herzegovina, Serbia, Bulgaria, Romania, Moldova, Montenegro and Ukraine) and the European Union. The commission, established in 1998, deals with the whole Danube river basin, which includes tributaries and the groundwater resources. Its goal is to implement the Danube River Protection Convention by promoting and coordinating sustainable and equitable water management, including conservation, improvement and rational use of waters and the implementation of the EU Water Framework Directive.

Navigation

The Danube Commission is concerned with the maintenance and improvement of the river's navigation conditions. It was established in 1948 by seven countries bordering the river. Members include representatives from Austria, Bulgaria, Croatia, Germany, Hungary, Moldova, Slovakia, Romania, Russia, Ukraine, and Serbia, It meets regularly twice a year. It also convenes groups of experts to consider items provided for in the commission's working plans. The commission dates to the Paris Conferences of 1856 and 1921, which established for the first time an international regime to safeguard free navigation on the Danube. Today the Commission include riparian and non-riparian states.

Geology

Although the headwaters of the Danube are relatively small today, geologically, the Danube is much older than the Rhine, with which its catchment area competes in today's southern Germany. This has a few interesting geological complications. Since the Rhine is the only river rising in the Alps mountains which flows north towards the North Sea, an invisible line beginning at Piz Lunghin divides large parts of southern Germany, which is sometimes referred to as the European Watershed. Before the last ice age in the Pleistocene, the Rhine started at the southwestern tip of the Black Forest, while the waters from the Alps that today feed the Rhine were carried east by the so-called ''Urdonau'' (original Danube). Parts of this ancient river's bed, which was much larger than today's Danube, can still be seen in (now waterless) canyons in today's landscape of the Swabian Alb. After the Upper Rhine valley had been eroded, most waters from the Alps changed their direction and began feeding the Rhine. Today's upper Danube is but a meek reflection of the ancient one. Since the Swabian Alb is largely shaped of porous limestone, and since the Rhine's level is much lower than the Danube's, today subsurface rivers carry much water from the Danube to the Rhine. On many days in the summer, when the Danube carries little water, it completely oozes away noisily into these underground channels at two locations in the Swabian Alb, which are referred to as the Donauversickerung (Danube Sink). Most of this water resurfaces only south at the Aachtopf, Germany's wellspring with the highest flow, an average of , north of Lake Constance—thus feeding the Rhine. The European Water Divide applies only for those waters that pass beyond this point, and only during the days of the year when the Danube carries enough water to survive the sink holes in the Donauversickerung. Since such large volumes of underground water erode much of the surrounding limestone, it is estimated that the Danube upper course will one day disappear entirely in favor of the Rhine, an event called stream capturing. The hydrological parameters of Danube are regularly monitored in Croatia at Batina, Dalj, Vukovar and Ilok.

History

The Danube basin was the site of some of the earliest human cultures. The Danubian Neolithic cultures include the Linear Pottery cultures of the mid-Danube basin. Many sites of the sixth-to-third millennium BC Vinča culture, (Vinča, Serbia) are sited along the Danube. The third millennium BC Vučedol culture (from the Vučedol site near Vukovar, Croatia) is famous for its ceramics. Darius the Great, king of Persia, crossed the river in the late 6th century BC to invade European Scythia and to subdue the Scythians. Alexander the Great defeated the Triballian king Syrmus and the northern barbarian Thracian and Illyrian tribes by advancing from Macedonia as far as the Danube in 336 BC. Under the Romans the Danube formed the border of the Empire with the tribes to the north almost from its source to its mouth. At the same time it was a route for the transport of troops and the supply of settlements downstream. From AD 37 to the reign of the Emperor Valentinian I (364–375) the Danubian Limes was the northeastern border of the Empire, with occasional interruptions such as the fall of the Danubian Limes in 259. The crossing of the Danube into Dacia was achieved by the ''Imperium Romanum'', first in two battles in 102 and then in 106 after the construction of a bridge in 101 near the garrison town of Drobeta at the Iron Gate. This victory over Dacia under Decebalus enabled the Province of Dacia to be created, but in 271 it was lost again. Avars used the river as their southeastern border in the 6th century.

Ancient cultural perspectives of the lower Danube

Part of the rivers Danubius or Istros was also known as (together with the Black Sea) the ''Okeanos'' in ancient times, being called the ''Okeanos Potamos'' (Okeanos River). The lower Danube was also called the ''Keras Okeanoio'' (Gulf or Horn of Okeanos) in the ''Argonautica'' by Apollonius Rhodos (Argon. IV. 282). At the end of the ''Okeanos Potamos'', is the holy island of Alba (Leuke, Pytho Nisi, Isle of Snakes), sacred to the Pelasgian (and later, Greek) Apollo, greeting the sun rising in the east. Hecateus Abderitas refers to Apollo's island from the region of the Hyperboreans, in the Okeanos. It was on Leuke, in one version of his legend, that the hero Achilles was buried (to this day, one of the mouths of the Danube is called Chilia). Old Romanian folk songs recount a white monastery on a white island with nine priests.''Dacia Preistorica''
, Nicolae Densusianu (1913).


Rivalry along the Danube

Between the late 14th and late 19th centuries, the Ottoman Empire competed first with the Kingdom of Serbia, Second Bulgarian Empire, Kingdom of Hungary, Principality of Wallachia, Principality of Moldavia and later with the Austrian Habsburgs, Polish–Lithuanian Commonwealth, and Russian Empire for controlling the Danube (''Tuna'' in Turkish), which became the northern border of the Ottoman Empire for centuries. Many of the Ottoman–Hungarian Wars (1366–1526) and Ottoman–Habsburg wars (1526–1791) were fought along the river. The most important wars of the Ottoman Empire along the Danube include the Battle of Nicopolis (1396), the Siege of Belgrade (1456), the Battle of Mohács (1526), the first Turkish Siege of Vienna (1529), the Siege of Esztergom (1543), the Long War (1591–1606), the Battle of Vienna (1683), the Great Turkish War (1683–1699), the Crimean War (1853–1856) and the Russo-Turkish War (1877–1878).

Economics



Drinking water

Along its course, the Danube is a source of drinking water for about 20 million people. In Baden-Württemberg, Germany, almost 30 percent (as of 2004) of the water for the area between Stuttgart, Bad Mergentheim, Aalen and Alb-Donau (district) comes from purified water of the Danube. Other cities such as Ulm and Passau also use some water from the Danube. In Austria and Hungary, most water is drawn from ground and spring sources, and only in rare cases is water from the Danube used. Most states also find it too difficult to clean the water because of extensive pollution; only parts of Romania where the water is cleaner still obtain drinking water from the Danube on a regular basis.

Navigation and transport

In the 19th century, the Danube was an important waterway but was, as ''The Times'' of London put it, "annually swept by ice that will lift a large ship out of the water or cut her in two as if she were a carrot." Today, as "Corridor VII" of the European Union, the Danube is an important transport route. Since the opening of the Rhine–Main–Danube Canal, the river connects the Port of Rotterdam and the industrial centres of Western Europe with the Black Sea and, also, through the Danube – Black Sea Canal, with the Port of Constanța. The waterway is designed for large-scale inland vessels () but it can carry much larger vessels on most of its course. The Danube has been partly canalized in Germany (5 locks) and Austria (10 locks). Proposals to build a number of new locks to improve navigation have not progressed, due in part to environmental concerns. Downstream from the Freudenau locks in Vienna, canalization of the Danube was limited to the Gabčíkovo dam and locks near Bratislava and the two double Iron Gate locks in the border stretch of the Danube between Serbia and Romania. These locks have larger dimensions. Downstream of the Iron Gate, the river is free flowing all the way to the Black Sea, a distance of more than . The Danube connects with the Rhine–Main–Danube Canal at Kelheim, with the Donaukanal in Vienna, and with the Danube–Black Sea Canal at Cernavodă. Apart from a couple of secondary navigable branches, the only major navigable rivers linked to the Danube are the Drava, Sava and Tisa. In Serbia, a canal network also connects to the river; the network, known as the Danube–Tisa–Danube Canals, links sections downstream. In the Austrian and German sections of the Danube, a type of flat-bottomed boat called a Zille was developed for use along the river. Zillen are still used today for fishing, ferrying, and other transport of goods and people in this area.

Fishing

The importance of fishing on the Danube, which was critical in the Middle Ages, has declined dramatically. Some fishermen are still active at certain points on the river, and the Danube Delta still has an important industry. However, some of the river's resources have been managed in an environmentally unsustainable manner in the past, leading to damage by pollution, alterations to the channel and major infrastructure development, including large hydropower dams. The sturgeon stocks associated with the Danube River basin have, over the centuries, formed the basis of a large and significant commercial fishery, renowned throughout the world. The construction of the dams, beside overfishing and river pollution has a significant role over sturgeon population decline because create a barrier for fish migratory species that usually spawn in the upper parts of the river. The spawning areas of migratory fishes species has been dramatically reduced by the construction of hydropower and navigation systems at Iron Gates I (1974) and Iron Gates II (1984). The initial design of these dams has not included any fish passage facility. The possibility of building a man-made fish pass enabling migration for fish species including the sturgeon, is currently under review by projects such as We Pass. The Upper Danube ecoregion alone has about 60 fish species and the Lower Danube–Dniester ecoregion has about twice as many.Hales, J. (2013).

'. Freshwater Ecoregions of the World. Retrieved 25 February 2013.
Among these are an exceptionally high diversity of sturgeon, a total of six species (beluga, Russian sturgeon, bastard sturgeon, sterlet, starry sturgeon and European sea sturgeon), but these are all threatened and have largely–or entirely in the case of the European sea sturgeon–disappeared from the river. The huchen, one of the largest species of salmon, is endemic to the Danube basin, but has been introduced elsewhere by humans.

Tourism

Important tourist and natural spots along the Danube include the Wachau Valley, the Nationalpark Donau-Auen in Austria, Gemenc in Hungary, the Naturpark Obere Donau in Germany, Kopački rit in Croatia, Iron Gate in Serbia and Romania, the Danube Delta in Romania, and the Srebarna Nature Reserve in Bulgaria. Also, leisure and travel cruises on the river are of significance. Besides the often frequented route between Vienna and Budapest, some ships even go from Passau in Germany to the Danube Delta and back. During the peak season, more than 70 cruise liners are in use on the river, while the traffic-free upper parts can only be discovered with canoes or boats. The Danube region is not only culturally and historically of importance, but also due to its fascinating landmarks and sights important for the regional tourism industry. With its well established infrastructure regarding cycling, hiking and travel possibilities, the region along the Danube attracts every year an international clientele. In Austria alone, there are more than 14 million overnight stays and about 6.5 million arrivals per year. The Danube Banks in Budapest are a part of Unesco World Heritage sites, they can be viewed from a number of sightseeing cruises offered in the city. The Danube Bend is also a popular tourist destination.

Danube Bike Trail

The Danube Bike Trail (also called Danube Cycle Path or the ''Donauradweg'') is a bicycle trail along the river. Especially the parts through Germany and Austria are very popular, which makes it one of the 10 most popular bike trails in Germany. The Danube Bike Trail starts at the origin of the Danube and ends where the river flows into the Black Sea. It is divided into four sections: #DonaueschingenPassau (559 km) #PassauVienna (340 km) #ViennaBudapest (306 km) #BudapestBlack Sea (1670 km)

Sultans Trail

The Sultans Trail is a hiking trail that runs along the river between Vienna and Smederevo in Serbia. From there the Sultans Trail leaves the Danube, terminating in Istanbul. Sections along the river are as follows. #ViennaBudapest (323 km) #BudapestSmederevo (595 km)

Donausteig

In 2010 the Donausteig, a hiking trail from Passau to Grein, was opened. It is long and it is divided into 23 stages. The route passes five Bavarian and 40 Austrian communities. An impressive landscape and beautiful viewpoints, which are along the river, are the highlights of the ''Donausteig''.

The Route of Emperors and Kings

The Route of Emperors and Kings is an international touristic route leading from Regensburg to Budapest, calling in Passau, Linz and Vienna. The international consortium ''ARGE Die Donau-Straße der Kaiser und Könige'', comprising ten tourism organisations, shipping companies, and cities, strives for the conservation and touristic development of the Danube region. In medieval Regensburg, with its maintained old town, stone bridge and cathedral, the Route of Emperors and Kings begins. It continues to Engelhartszell, with the only Trappist monastery in Austria. Further highlight-stops along the Danube, include the "Schlögener Schlinge", the city of Linz, which was European Capital of Culture in 2009 with its contemporary art richness, the Melk Abbey, the university city of Krems and the cosmopolitan city of Vienna. Before the Route of Emperors and Kings ends, you pass Bratislava and Budapest, the latter which was seen as the twin town of Vienna during the times of the Austro-Hungarian Empire. Since ancient Roman times, famous emperors and their retinue travelled on and along the Danube and used the river for travel and transportation. While travelling on the mainland was quite exhausting, most people preferred to travel by ship on the Danube. So the Route of Emperors and Kings was the setting for many important historical events, which characterize the Danube up until today. The route got its name from the Holy Roman Emperor Frederick I of Barbarossa and the crusaders as well as from Richard I of England who had been jailed in the Dürnstein Castle, which is situated above the Danube. The most imperial journeys throughout time were those of the Habsburg family. Once crowned in Frankfurt, the emperors ruled from Vienna and also held in Regensburg the Perpetual Diet of Regensburg. Many famous castles, palaces, residences and state-run convents were built by the Habsburger along the river. Nowadays they still remind us of the bold architecture of the "Donaubarock". Today, people can not only travel by boat on the Danube, but also by train, by bike on the Danube Bike Trail or walk on the "Donausteig" and visit the UNESCO World Heritage cities of Regensburg, Wachau and Vienna.

In popular culture
