On September 16, 1970,
King Hussein of Jordan declared martial law and appointed Brigadier Mohammad Daoud as Prime Minister to lead the first military government in
Jordan. Despite efforts to defuse the tension between the Jordanian army and the Palestinian movements, between 16 and 25 September 1970, the escalating conflict resulted in the death of thousands and this conflict became known as
Black September (also known as the
Jordanian Civil War). An
Arab League Summit Committee assigned Kuwaiti Minister of Defense
Saad Al-Sabah, Sudanese head of state
Gaafar Nimeiry, and the Deputy Foreign Minister of Saudi Arabia,
Omar Al Saqqaf to investigate and report back the cause of the clash to the Arab summit. Meanwhile, the
Arab League held a meeting for all the head of Arab states in Cairo. King Hussein assigned Al-Abbasi to join the summit. After 10 days only as a prime minister, on 24 September, out of frustration and pressure after being unable to avoid this developing conflict and the devastating results, Al-Abbasi submitted his resignation from his position to the Jordanian Ambassador in Cairo,
Hazem Nuseibeh. Al-Abbasi requested
political asylum in Cairo, following his resignation. Egyptian president,
Gamal Abdel Nasser, asked Al-Abbasi to stay in Cairo for consultation of Jordanian affairs. The timing of this resignation amidst all the turbulent and rapidly developing events at that time came as a surprise to many, and it had a dramatic impact in ending the military conflict in Jordan at a faster pace. ==Illness and death==
