The outcome of the Crimean War (1853-1856) for Russia was largely detrimental, leading to significant territorial and diplomatic losses. Russia aimed to expand its influence in the Black Sea region but faced a coalition of Britain, France, the Kingdom of Sardinia, and the Ottoman Empire. The war concluded with the Treaty of Paris in 1856, which restricted Russian naval power in the Black Sea and signaled a decline in Russian influence in Europe, ultimately prompting reforms within the Russian Empire.
