The French Mandate was settled at the San Remo Conference and comprised the region between the Euphrates River and the Syrian Desert on the east and the Mediterranean Sea on the west, and it extended from the Nur Mountains in the north to Egypt in the south, an area of about with a population of about 3,000,000, including the Lebanon and an enlarged Syria, both of which were later reassigned under a League of Nations Mandate. The region was divided under the French into four governments as follows: Government of Aleppo, from the Euphrates region to the Mediterranean; Great Lebanon, extending from Tripoli to Palestine; Damascus, including Damascus, Hama, Hems and the Hauran; and the country of Mount Arisarieh. Faisal ibn Husayn, who had been proclaimed king of Syria by a Syrian National Congress in Damascus in March 1920, was ejected by the French in July the same year. The next year, he became king of Iraq.
