Danube River Facts
From the Black Forest to the Black Sea
Danube Key Facts & Figures
Ancient Greeks navigated up the Danube from the Black Sea, as far as the Iron Gate. Later, river transport was developed by the Romans; many cities along the Danube began as Roman military outposts. In medieval times, goods were moved either by boat or barge, or along its banks, fostering development of the Habsburg and Hungarian empires.
The Danube flows through ten modern-day European nations: Germany, Austria, Slovakia, Hungary, Croatia, Serbia, Bulgaria, Ukraine, Moldova and Romania.

A brief history of the Danube
Some of the earliest human cultures on Earth were sited in the Danube basin, including such Neolithic peoples as the Linear Pottery and Vinča cultures. By the first millennium BC, ancient Greeks explored and traded along the lower Danube as far as the Iron Gate.
Under Julius Caesar, Rome expanded its reach along the Danube (Davinius); Roman ships patrolled its waters, and settlements grew out of Roman military posts – Aquincum (Budapest), Singidunum (Belgrade), Sexantaprista (Ruse), and Vindobona (Vienna).
After the fall of the Roman Empire, castles and fortresses were built along the Danube by Charlemagne (Werfenstein, 9th century) and other rulers throughout the Middle Ages, as various kingdoms merged into Austria’s Habsburg Empire by the 14th century.
Between the 14th and 19th centuries, the Ottoman Turks struggled with the Hungarian and later Austrian (Habsburg) Empires for control of the Danube; the river formed the Ottoman Empire's northern border for centuries.
With the breakup of both the Ottoman and Austro-Hungarian empires after World War I, the upheaval of World War II, the Cold War, the Balkan wars and the formation of the European Union, the Danube region saw many changes across the decades.
Today, with its borders generally settled, the Danube is an important transport route for the whole of Europe, and is designated as "Corridor VII" of the European Union. Since the opening of the Rhine–Main–Danube Canal and the Danube-Black Sea Canal, the Danube links the North Sea and western Europe with the ports of the Black Sea.
