Crimean War The Crimean War (French: Guerre de Crimée; Russian: Кры́мская война́, translit. Krymskaya voina or Russian: Восто́чная война́, translit. Vostochnaya voina, lit. 'Eastern War'; Turkish: Kırım Savaşı; Italian: Guerra di Crimea) was a military conflict fought from October 1853 to February 1856[6] in which the Russian Empire lost to an alliance of the Ottoman Empire, France, Britain and Sardinia. The immediate cause involved the rights of Christian minorities in the Holy Land, which was a part of the Ottoman Empire. The French promoted the rights of Roman Catholics, while Russia promoted those of the Eastern Orthodox Church. The longer-term causes involved the decline of the Ottoman Empire and the unwillingness of Britain and France to allow Russia to gain territory and power at Ottoman expense. It has widely been noted that the causes, in one case involving an argument over a key, have never revealed a "greater confusion of purpose", yet led to a war noted for its "notoriously incompetent international butchery".[7]
History of the Ottoman Empire during World War I The Ottoman Empire participated in World War I as one of the Central Powers. The Ottoman Empire entered the war by carrying out a surprise attack on Russia's Black Sea coast on 29 October 1914, with Russia responding by declaring war on 5 November 1914. Ottoman forces fought the Entente in the Balkans and the Middle Eastern theatre of World War I. The Ottoman Empire's defeat in the war in 1918 was crucial in the eventual dissolution of the empire in 1921.
