As Grand Mufti and leader in the Arab Higher Committee, especially during the war period 1938-45, al-Husayni played a key role in violent opposition to Zionism and closely allied himself with the Nazi regime in Germany.[5][6] In 1948, after Jordan occupied Jerusalem, Abdullah I of Jordan officially removed al-Husayni from the post, banned him from entering Jerusalem, and appointed Hussam Al-din Jarallah as Grand Mufti. On the death of Jarallah in 1952, the Jordanian Waqf appointed Saad al-Alami as his replacement.[7]
