The Gallipoli Campaign, also known as the Dardanelles Campaign, the Battle of Gallipoli or the Battle of Çanakkale (Turkish: Çanakkale Savaşı), was a campaign of World War I that took place on the Gallipoli peninsula (Gelibolu in modern Turkey) in the Ottoman Empire between 25 April 1915 and 9 January 1916. The peninsula forms the northern bank of the Dardanelles, a strait that provided a sea route to the Russian Empire, one of the Allied powers during the war.
