With the break-up of the Ottoman Empire at the end of World War I, the League of Nations created the French Mandate of Syria and British Mandate Palestine. Approximately 90% of the British Mandate of Palestine was east of the Jordan river and was known as “Transjordan”. In 1921, the British gave semi-autonomous control of Transjordan to the future King Abdullah I of Jordan, of the Hashemite family. Abdullah I continued to rule until a Palestinian Arab assassinated him in 1951 on the steps of the Mosque of Omar. At first he ruled “Transjordan”, under British supervision until after World War II. In 1946, the British requested that the United Nations approve an end to British Mandate rule in Transjordan. Following this approval, the Jordanian Parliament proclaimed King Abdullah as the first ruler of the Hashemite Kingdom of Jordan.
In 1950, Jordan annexed the West Bank, which had been under its control since the armistice that followed the 1948 Arab-Israeli war. The annexation was recognized only by the United Kingdom (de facto in the case of East Jerusalem).
In 1965, there was an exchange of land between Saudi Arabia and Jordan. Jordan gave up a relatively large area of inland desert in return for a small piece of sea-shore near Aqaba.
Jordan signed a mutual defence pact in May 1967 with Egypt, and it participated in the June 1967 war against Israel along with Syria, Egypt, and Iraq. During the war, Jordan lost the West Bank and East Jerusalem to Israel (the western sector having been under Israeli control). In 1988, Jordan renounced all claims to the West Bank but retained an administrative role pending a final settlement, and its 1994 treaty with Israel allowed for a continuing Jordanian role in Muslim and Christian holy places in Jerusalem.
Refugees and Black September / AKA White September
The 1967 war led to a dramatic increase in the number of Palestinians, especially from the West Bank, living in Jordan. Its Palestinian refugee population — 700,000 in 1966 — grew by another 300,000 from the West Bank. The period following the 1967 war saw an upsurge in the power and importance of Palestinian resistance elements (fedayeen) in Jordan. The fedayeen were targeted by King’s (Hussien) armed forces, and open fighting erupted in June 1970. The battle in which Palestinian fighters from various Palestine Liberation Organization (PLO) groups were expelled from Jordan is commonly known as Black September, it is also known as white September to many.
The heaviest fighting occurred in northern Jordan and Amman. The Syrian army battled the Jordanian army in Amman and other urban areas. The global media portrayed King Hussein as a corrupt King slaughtering the Palestinian refugees. Other Arab governments attempted to work out a peaceful solution. In the ensuing heavy fighting, a Syrian tank force invaded northern Jordan to support the fedayeen but subsequently retreated. It is said by some people, such as Ahmed Jibril, that King Hussein asked for help from Israel, then Israel threatened that it would invade Jordan if Syria intervened. By September 22, Arab foreign ministers meeting at Cairo had arranged a cease-fire beginning the following day. Sporadic violence continued, however, until Jordanian forces led by Habis Al-Majali with the help of the Iraqi forces (who had bases in Jordan after the war of 1967), won a decisive victory over the fedayeen on July 1971, expelling them from the country.
At the Rabat summit conference in 1974, Jordan agreed, along with the rest of the Arab League, that the PLO was the “sole legitimate representative of the Palestinian people”, thereby relinquishing to that organization its role as representative of the West Bank.
Post Black September and Peace Treaty
Fighting occurred along the 1967 Jordan River cease-fire line during the October 1973 Arab-Israeli war, but Jordan sent a brigade to Syria to fight Israeli units on Syrian territory. Jordan did not participate in the Gulf War of 1990–91. In 1991, Jordan agreed, along with Syria, Lebanon, and Palestinian fedayeen representatives, to participate in direct peace negotiations with Israel at the Madrid Conference, sponsored by the U.S. and Russia. It negotiated an end to hostilities with Israel and signed a declaration to that effect on July 25, 1994 (see Washington Declaration). As a result, an Israeli-Jordanian peace treaty was concluded on October 26, 1994. Following the outbreak of Israel-Palestinian Authority fighting in September 2000, the Jordanian government offered its good offices to both parties. Jordan has since sought to remain at peace with all of its neighbors.
On November 9, 2005 Jordan experienced three simultaneous bombings at hotels in Amman. At least 57 people died and 115 were wounded. “Al-Qaeda in Iraq”, a group led by terrorist Abu Musab al-Zarqawi, a native Jordanian, claimed responsibility.
