The Danube ( /ˈdænjuːb/ DAN-yoob) is a river in Central Europe, the continent's second longest after the Volga.

Classified as an international waterway, it originates in the town of Donaueschingen which is in the Black Forest of Germany at the confluence of the rivers Brigach and Breg. The Danube then flows southeast for 2,872 km (1,785 mi), passing through four Central European capitals 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 ten countries: Romania (29.0% of basin area), Hungary (11.6%), Serbia (10.2%), Austria (10.0%), Germany (7.0%), Slovakia (5.9%), Bulgaria (5.9%), Croatia (4.4%), Ukraine (3.8%), and Moldova (1.6%), more than any other. Its drainage basin extends into nine more.

Famous quotes containing the word danube:

    The Danube to the Severn gave
    The darken’d heart that beat no more;
    They laid him by the pleasant shore,
    And in the hearing of the wave.
    Alfred Tennyson (1809–1892)
