The Sharifian Army, also known as the Arab Army, or the Hejazi Army was the military force behind the Arab Revolt which was a part of the Middle Eastern theatre of World War I. Sharif Hussein Ibn Ali of the Kingdom of Hejaz, who was proclaimed "Sultan of the Arabs" in 1916, led the Sharifian Army in a rebellion against the Ottoman Empire with the ultimate goal of uniting the Arab people under an independent government.
