Political map of South & Southwest Asia 9 July 1916 (Arab Revolt): Britain's attempts to incite rebellion in its opponents' empires had been largely unsuccessful. Finally in 1916 they persuaded the Sharif of Mecca (Hussein bin Ali, Sharif of Mecca) to revolt against his Ottoman overlords and declare the Kingdom of Hejaz (Battle of Mecca (1916)). With British-supplied arms, the Sharif took control of the region, threatening to overthrow Ottoman rule in Arabia (Arab Revolt).
