Peace Concluded between England & Russia; The Crimean War (October 1853 – February 1856) was a conflict fought between the Russian Empire and an alliance of the French Empire, the British Empire, the Ottoman Empire, the Kingdom of Sardinia, and the Duchy of Nassau. The war was part of a long-running contest between the major European powers for influence over territories of the declining Ottoman Empire. Most of the conflict took place on the Crimean Peninsula, but there were smaller campaigns in western Anatolia, the Baltic Sea, the Pacific Ocean and the White Sea.
