The 1927 Jericho earthquake destroyed many of the Nablus' historic buildings, including the An-Nasr Mosque. Though they were subsequently rebuilt by Haj Amin al-Husayni's Supreme Muslim Council in the mid-1930s, their previous "picturesque" character was lost. During British rule, Nablus emerged as a site of local resistance and the Old City quarter of Qaryun was demolished by the British during the 1936–1939 Arab revolt in Palestine. Jewish immigration did not significantly impact the demographic composition of Nablus, and it was slated for inclusion in the Arab state envisioned by the United Nations General Assembly's 1947 partition plan for Palestine.
