what event promoted the ottoman empire to enter the war
Ottoman entry into World War I The Ottoman Empire's entry into World War I began when its navy carried out a surprise attack on Russia's Black Sea coast on 29 October 1914, following which Russia declared war on it on 1 November 1914. Russia's allies, Britain and France, then declared war on the Ottoman Empire on 5 November 1914. The reasons for the Ottoman action were not immediately clear, since the Empire was not formally allied with any of the great powers.[1] This decision would ultimately lead to the deaths of hundreds of thousands of Ottomans and the eventual dissolution of the empire and abolition of the Islamic Caliphate.[2][3][4]
