The 1856 Treaty of Paris settled the Crimean War between the Russia Empire and an alliance made up of the Great Britain, the Ottoman Empire and the Kingdom of Sardinia.
The Crimean War had begun in 1853 with Russian encroaching on territories under Ottoman control. The terms of the treaty made the Black Sea neutral territory and forbade any military build-up in the area. It also freed up trade for all countries along the Danube river. Russia was forced to give up a number of territories and received back areas taken by the alliance including Sevastopol and Balaklava.
