In the Middle East, Arab nationalism soared in Ottoman territories in response to the rise of Turkish nationalism during the war, with Arab nationalist leaders advocating the creation of a pan-Arab state. In 1916, the Arab Revolt began in Ottoman-controlled territories of the Middle East in an effort to achieve independence. In East Africa, Iyasu V of Ethiopia was supporting the Dervish state who were at war with the British in the Somaliland campaign. Von Syburg, the German envoy in Addis Ababa, said, "now the time has come for Ethiopia to regain the coast of the Red Sea driving the Italians home, to restore the Empire to its ancient size."

Some historians claim the British spy T. E. Lawrence forged the Iyasu photo. A number of socialist parties initially supported the war when it began in August 1914.
