سوريا الكبرى
Until late 1920, al-Husseini focused his efforts on Pan-Arabism and the ideology of a Greater Syria in particular, with Palestine understood as a southern province of an Arab state, whose capital was to be established in Damascus. Greater Syria was to include territory of the entire Levant, now occupied by Syria, Lebanon, Jordan, Palestinian Authority and Israel. The struggle for Greater Syria collapsed after France defeated the Arab forces in Battle of Maysalun in July 1920. The French army entered Damascus at that time, overthrew King Faisal and put an end to the project of a Greater Syria, put under the French Mandate in accordance with the prior Sykes-Picot Agreement. Palestinian notables responded to the disaster by a series of resolutions at the 1921 Haifa conference, which set down a Palestinian framework and passed over in silence the earlier idea of a south confederated with Syria. This framework set the tone of Palestinian nationalism for the ensuing decades.
