Muhammad Amin al-Husayni (1895-1974) was the Grand Mufti of Jerusalem (1921-1948) and a Palestinian nationalist leader who worked to prevent the establishment of a Jewish state in Palestine. Al-Husayni attended the 1919 Pan-Syrian Congress in Damascus, where he supported the creation of a nationalist Syrian Arab state that would encompass Syria, Jordan, Lebanon, and Palestine, then later went on to support an individual Palestinian state.
