The Crimean War (1853-1856) was the war fought over the influence of the Black Sea during the decline of the Ottoman Empire. The war was the first war to be documented mainly in photographs, and used railroads and telegraphs for stratigic purposes. The Russian Empire fought the alliance of British Empire, the French Empire, Ottoman Empire, and the kingdom of Sardinia. The main battle was fought on the Crimean Peninsula and the Black Sea. Many of the battles were known for their stratigic blunders on both sides. The war ended in 1856 when Tsar Alexander II worked with peace negotiations began through the congress of Paris. Ultimately, Russia lost its influence of the Black Sea and had to respect the territorial influence of the Ottoman Empire.
