Black Sea Treaty.

A treaty signed in London in 1871 by the signatories of the Treaty of Paris of 1856. In 1870, Russia, taking advantage of the Franco-German war, issued a note, declaring herself no longer bound by the clause of that treaty neutralising the Black Sea. A conference was called in London to consider the situation, and by the resulting treaty the clause in question was abrogated. The conference also took the opportunity to prolong the existence of the Danubian Commission for a further period of twelve years.
