Europe's second-longest river, flowing about 2,850 km from Germany's Black Forest to the Black Sea through ten countries.
The Danube is the second-longest river in Europe after the Volga, flowing about 2,850 km from its source in the Black Forest of southwestern Germany southeastwards to the Black Sea. It passes through or forms the border of ten countries, more than any other river in the world, and flows through four national capitals. Since the completion of the Rhine-Main-Danube Canal in 1992, it has formed part of a continuous inland waterway connecting the North Sea to the Black Sea.

The Danube is the textbook example of an international river, and of the governance problems that come with one. Ten states share it, and what one does upstream — abstracting water, discharging effluent, building a barrage — is felt by every state downstream. That interdependence has produced one of the world's more developed river-basin governance regimes, and also one of the best-known international water disputes, the Gabcikovo-Nagymaros case between Hungary and Slovakia decided by the International Court of Justice. Its lessons are directly relevant to India's own transboundary rivers, where similar upstream-downstream asymmetries shape relations with Pakistan, Bangladesh, Nepal and China.
