The Danube Commission (German: Donaukommission, Russian: Дунайская комиссия, romanized: Dunayskaya komissiya, French: Commission du Danube) is concerned with the maintenance and improvement of navigation conditions of the Danube River, from its source in Germany to its outlets in Romania and Ukraine, leading to the Black Sea. It was established in 1948 by seven countries bordering the river, replacing previous commissions that had also included representatives of non-riparian powers. Its predecessor commissions were among the first attempts at internationalizing the police powers of sovereign states for a common cause.
