By the end of World War II, the Palestinian Arabs were leaderless. The mufti of Jerusalem Hajj Amin al-Husayni had been in exile since 1937 and spent the war years in occupied Europe, actively collaborating with Nazi leadership. As the war ended, he managed to escape to Egypt and stayed there until his death in 1974. His brother Jamal al-Husayni was interned in Southern Rhodesia during the war. In November 1945, the Arab League reestablished the Arab Higher Committee as a supreme executive body of Palestinian Arabs in the territory of the British Mandate of Palestine, but it fell apart due to infighting. In June 1946, the Arab League imposed upon the Palestinians the Arab Higher Executive, renamed as "Arab Higher Committee" in 1947, with Amin al-Husayni as its chairman and Jamal al-Husayni as vice-chairman.
