The
Treaty of Paris of 1856 settled the
Crimean War between
Russia and an alliance of the
Ottoman Empire, the
British Empire,
Second French Empire, and the
Kingdom of Sardinia. The treaty, signed on 30 March 1856 at the
Congress of Paris, made the
Black Sea neutral territory, closing it to all warships, and prohibiting fortifications and the presence of armaments on its shores. The treaty marked a severe setback to Russian influence in the region. Conditions for the return of Sevastopol and other towns and cities in the south of Crimea were clear; "not to establish any naval or military arsenal on the Black Sea coast".
