The Crimean War (1853-56) is the expansion of what began as the ninth Russo-Turkish War. Britain and France entered the war on the Turkish side late in 1854, eventually followed by PiedmontSardinia. Despite the war’s proximity to Europe and the involvement of great powers, Austria and Prussia did not enter the war-a non-event that prevented the conflict from becoming a general war. After a year of siege warfare, the Western powers defeated the Russian forces in the Crimea and negotiated a settlement before the opening of the 1856 campaign.
