From 1915 the population of Mount Lebanon and the Syrian interior faced the combined effect of the Allied blockade of the eastern Mediterranean, the Ottoman army's requisitioning of grain, pack animals and transport for the Sinai and Palestine fronts, a land blockade of the largely Maronite mountain imposed by Cemal Pasha, and a locust plague that destroyed the 1915 crops across Syria and Palestine. Prices rose beyond reach, relief was obstructed, and mortality was extreme: contemporary and later estimates put deaths in Mount Lebanon at 150,000-200,000, roughly a third of its population, giving the district what is often described as the highest per capita wartime mortality of any bounded territory in the First World War, with a further large toll in the Syrian interior. Another third of the population emigrated. The famine is a central event in modern Lebanese memory and contributed to the case for a separate Lebanese entity under the French Mandate.
The Allied naval blockade of the eastern Mediterranean, Ottoman requisitioning and a land blockade imposed by the Fourth Army commander Cemal Pasha, and a locust invasion in 1915, together destroyed the food supply of Mount Lebanon and Syria
Ottoman administrative counts for the autonomous Mutasarrifate give roughly 400,000-415,000 inhabitants around 1913-14. Estimates of famine deaths in Mount Lebanon run from 100,000 to 200,000, that is a quarter to a half of the population, the highest proportional loss of any territory in the war; for Ottoman Syria as a whole, deaths are put at roughly 500,000.
Estimates for Mount Lebanon itself are 150,000-200,000 dead, about a third of the population, a figure repeated in Lebanese and international accounts and drawn from contemporary missionary, consular and church reporting rather than from registration. Wider estimates for Ottoman Syria as a whole, including Damascus, Aleppo and the interior, run to 300,000-500,000. Deaths were from starvation and the diseases that accompany it.
The blockade, the requisitioning of food and transport and the isolation of Mount Lebanon are documented in Ottoman, French, British and American consular and missionary reporting summarised in the cited accounts.
