San Remo conference
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 after which he contended that the conditions he appended were not fulfilled and the agreement therefore moot. According to contemporaries, including Gertrude Bell and T. E. Lawrence, the French, with British support, betrayed Faisal and the Arab cause rendering the treaty invalid.
