London Straits Convention

In the London Straits Convention concluded on 13 July 1841 between the Great Powers of Europe at the time—Russia, the United Kingdom, France, Austria and Prussia—the "ancient rule" of the Ottoman Empire was re-established by closing the Turkish Straits (the Bosporus and Dardanelles), which link the Black Sea to the Mediterranean, from all warships whatsoever, barring those of the Sultan's allies during wartime. It thus benefited British naval power at the expense of Russia as the latter lacked direct access for its navy to the Mediterranean.
