At the time, the term Southern Syria referred to a political position which implied support for the Greater Syria nationalism associated with the kingdom promised to the Hashemites of the Hejaz by the British during World War I. After the war, the Hashemite prince Faisal attempted to establish such a Pan-Syrian or pan-Mashriq state (i.e. a united kingdom that would comprise all of modern Syria, as well as Mount Lebanon and Palestine, including Transjordan, so that Palestine would be the province of Southern Syria). This kingdom was to be united with the other Hashemite domains in Hejaz and Iraq, thus contributing in large measure towards the fulfillment of Pan-Arabist ambitions. However, he was stymied by conflicting promises made by the British to different parties (see Sykes-Picot Agreement, Balfour Declaration and McMahon-Hussein Correspondence), leading to the Franco-Syrian War, which destroyed the Arab Kingdom of Syria in 1920.
