http://en.m.wikipedia.org/wiki/Palestinian_nationalismIn 1918, as the Palestinian Arab national movements gained strength in Jerusalem, Jaffa, Haifa, Acre and Nablus, Aref al-Aref joined Hajj Amīn, his brother Fakhri Al Husseini, Ishaaq Darweesh, Ibrahim Daeweesh, Jamal al-Husayni, Kamel Al Budeiri, and Sheikh Hassan Abu Al-So’oud in establishing the Arab Club.
Following the arrival of the British a number of Muslim-Christian Associations were established in all the major towns. In 1919 they joined together to hold the first Palestine Arab Congress in Jerusalem. Its main platforms were a call for representative government and opposition to the Balfour Declaration.
The Faisal-Weizmann Agreement led the Palestinian Arab population to reject the Syrian-Arab-Nationalist movement led by Faisal (in which many previously placed their hopes) and instead to agitate for Palestine to become a separate state, with an Arab majority. To further that objective, they demanded an elected assembly.[28]
