Jordan was ruled under martial law throughout most of the Cold War period, particularly starting in 1967 when tensions between the Hashemites and the Palestinian majority eventually led to a bloody civil war in 1970.

Then when Yasser Arafat took on that role in September 1970, al-Yehiyeh became chief-of-staff of all Palestinian forces.

The Black September Organization ( BSO ) (, Munaẓẓamat Aylūl al-aswad ) was a Palestinian terrorist organization, founded in 1970.

She became an Egyptian citizen in 1963, and in October 1970, Princess Dina of Jordan married Lieut-Colonel Asad Sulayman Abd al-Qadir, alias Salah Taamari, a Palestinian guerrilla commando who became a high-ranking official in the Palestine Liberation Organization.

On 6 September 1970, he and his wife, daughter, and son-in-law Yonasan David were returning to New York when their airplane was hijacked by the PFLP Palestinian terrorist organization.

In 1970 King Hussein waged the war of Black September against the Palestinian Liberation Organization ( PLO ), eventually ejecting the organization and thousands of Palestinians, who threatened Hussein's rule.

In September 1970 a bloody military struggle was held between Jordan and the Palestinian armed organizations.

In 1970, when conflict erupted between the Palestine Liberation Organization ( PLO ) and the Jordanian army, Jadid sent Syrian-controlled Palestinian troops of the nominally PLO-run Palestinian Liberation Army, based in Syria, into Jordan in order to help the PLO.

Mr. Talhouni was Prime Minister from August 1969 to June 1970, during a particularly turbulent time of friction and skirmishes between the Government and thousands of Palestinian guerrillas who were then in Jordan.

He played an important role in the 1970 – 71 Black September clashes in Jordan, by supplying surrounded Palestinian fighters with weapons and aid.

When al-Assad seized power in the November 1970 " Corrective Revolution ", the organization was purged and its leadership replaced with al-Assad loyalists ( although Jadid loyalists held on to the as-Sai ' qa branch active in the Palestinian refugee camps in Jordan until mid-1971, when they were arrested ).

In exile, Fu ' ad Nassar built up an armed militia for the Palestinian communists, the al-Ansar Forces, in March 1970.

In 1969 he was again in prison for participation in a demonstration on April 23 in support of the Palestinian cause, and again in 1970 for his part in attacking an army detachment.

He left Jordan in 1970 after the Palestinian guerrilla forces in the kingdom were crushed in Black September and travelled to Paris to continue his studies.

Professor Stephen M. Schwebel, at the time a deputy legal advisor to the U. S. Department of State, Legal Adviser Office ( 1961 – 1981 ), wrote in the American Journal of International Law ( 1970 ) that "... modifications of the 1949 armistice lines among those States within former Palestinian territory are lawful ( if not necessarily desirable ), whether those modifications are ...' insubstantial alterations required for mutual security ' or more substantial alterations-such as recognition of Israeli sovereignty over the whole of Jerusalem.
