The Gallipoli campaign, the Dardanelles campaign, the Defence of Gallipoli or the Battle of Gallipoli (Turkish: Gelibolu Muharebesi, Çanakkale Muharebeleri or Çanakkale Savaşı) was a military campaign in the First World War on the Gallipoli Peninsula (now Gelibolu) from 19 February 1915 to 9 January 1916. The Allied powers (Britain, France and the Russian Empire) unsuccessfully attempted to make the Ottoman Empire, one of the Central Powers, capitulate by taking control of the Turkish straits. They intended to expose the Ottoman capital at Constantinople to bombardment by Allied warships and cut it off from the Asian part of the empire.
