The Treaty of Paris is signed, ending the Crimean War.
The Treaty of Paris of 1856 brought an end to the Crimean War between the Russian Empire and an alliance of the Ottoman Empire, Great Britain, the 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 diminished Russian influence in the region. Conditions for the return of Sevastopol and other towns and cities in the south of Crimea to Russia were severe since no naval or military arsenal could be established by Russia on the coast of the Black Sea.
