San Remo conference
Following the collapse of the Ottoman Empire after World War I, the League of Nations mandated the five provinces that make up present-day Lebanon to the direct control of France. Initially the division of the Arabic-speaking areas of the Ottoman Empire were to be divided by the Sykes–Picot Agreement; however, the final disposition was at the San Remo conference of 1920, whose determinations on the mandates, their boundaries, purposes and organization was ratified by the League in 1921 and put into effect in 1922.
