The Middle Eastern theatre of World War I saw action between 29 October 1914 and 30 October 1918. The combatants were, on one side, the Ottoman Empire (including Kurds and some Arab tribes), with some assistance from the other Central Powers; and on the other side, the British (with the help of Jews, Greeks, Assyrians and the majority of the Arabs, along with Indians under its empire), the Russians (with the help of Armenians and Assyrians) and the French from among the Allied Powers. There were five main campaigns: the Sinai and Palestine Campaign, the Mesopotamian Campaign, the Caucasus Campaign, the Persian Campaign, and the Gallipoli Campaign. There were also several minor campaigns: Arab Campaign, and South Arabia Campaign.
