Russia played a relatively minor role in the Napoleonic Wars until 1812, when the Imperial Russian Army virtually destroyed Napoleon's huge army when it invaded Russia. Russia played a major role in the eventual defeat of Napoleon and in setting conservative terms for the restoration of aristocratic Europe during the period of 1815 to 1848. Russia conducted several wars with the Ottoman Empire between 1568 and 1918, and in 1856 Russia lost the Crimean War to a coalition of Great Britain, France and the Ottoman Empire. More small wars followed in the late-19th century.
