A significant diplomatic victory was scored by tiny [[Kingdom of Sardinia|Piedmont]] that, although not being yet considered a "great" European power, was nevertheless granted a seat at the Congress by the French Emperor [[Napoleon III]], mostly for having sent an expeditionary corps of 18,000 men to fight against Russia along with France and Prussia, but also possibly because of the intrigues of the very attractive [[Virginia Oldoini|Countess of Castiglione]], who had caught the Emperor's attention. The Piedmontese foreign minister [[Camillo Benso di Cavour]] seized this opportunity to denounce Austrian political and military interference in the Italian peninsula that he said was stifling the wish of the Italian people to choose their own government.

The Congress resulted in a pledge by all
of the powers to jointly maintain "the integrity of the Ottoman Empire" . It also guaranteed Turkey's independence.<ref name="Britannica"/>
Also, Russia gave up the left bank of the mouth of the Danube River, including part of [[Bessarabia]]<ref name="Congress"/> to [[Moldavia]]
and gave up its claim to the special protection of Christians in the Ottoman Empire. Moldavia and [[Wallachia]] (which together later became [[Romania]] in 1858 ) along with Serbia were recognized as quasi-independent self-governing principalities under protection of the other European Powers. The sultan of Turkey agreed, in return, to help improve the status of the Christian subjects in his empire.<ref name="Congress"/>
The territories of Russia and
Turkey were restored to their prewar boundaries.<ref name="Congress"/> The [[Black Sea]] was neutralized so that no warships were allowed to enter ; however, it was open to all other nations.<ref name="Congress"/> It also opened the [[Danube River]] for shipping from all nations.<ref name="Britannica"/>
Turkish historians still express dissatisfaction
with this fact. By example: "Although Ottoman Empire was on the side of winners, the Porte also lost the right to have a navy in the Black Sea together with the Russia. Put differently, the Empire had become a part of the European Concert, but not an actor in the European balance of power. Thus it was not recognized as a great power that could claim compensation in case of territorial gain by another member of the system".<ref name="Candan Badem 1856 p.403">Candan Badem, The Ottoman Crimean War (1853-1856).
