In 1920, following World War I, the area of the Mutasarrifate, plus some surrounding areas which were predominantly Shia and Sunni, became a part of the state of Greater Lebanon under the French Mandate of Syria and Lebanon. Around 100,000 people in Beirut and Mount Lebanon died of starvation during World War I. In the first half of 1920, Lebanese territory was claimed as part of the Arab Kingdom of Syria, but shortly the Franco-Syrian War resulted in Arab defeat and capitulation of the Hashemites.
