A Palestinian nationalist movement emerged immediately in 1918 with statist sovereignty aims

Evidence

This view of Palestinian Arab society was, however, incorrect. Inspired by the Allied message of Arab national freedom, a specifically Palestinian nationalist movement erupted in the first year of British colonial rule in the Holy Land. This political movement drew on the powerful currents of Palestinian Arab national identity that existed before the war. By the end of 1918, the Palestinian elite had rallied around the newly formed Muslim-Christian Association that started in Jaffa and, alongside young intellectual groups such as the Arab Club and the Harvest of Studies in Jerusalem, demanded and expected Arab independence for Filastin. This statist nationalist political ideology mirrored the development of Zionism among the majority of its adherents, who, by 1918, expected to obtain Jewish national sovereignty over all of Eretz Israel. — James Renton, Ben Gidley (eds.), Antisemitism and Islamophobia in Europe, 693
