San Remo conference
On 7 March 1920, Faisal was proclaimed King of the Arab Kingdom of Syria (Greater Syria) by the Syrian National Congress government of Hashim al-Atassi. In April 1920, the San Remo conference gave France the mandate for Syria, which led to the Franco-Syrian War. In the Battle of Maysalun on 24 July 1920, the French were victorious and Faisal was expelled from Syria.
