Jordan

The land east of the Jordan River has been continuously inhabited since the Paleolithic, and Neolithic settlements such as Ain Ghazal near present-day Amman are among the oldest known agricultural communities, dating to roughly 7250 BCE. During the Bronze and Iron Ages the region was home to the kingdoms of Ammon, Moab, and Edom, all referenced in ancient Near Eastern and Hebrew sources, while the northern reaches lay within successive spheres of Egyptian, Hittite, Assyrian, Babylonian, and Persian influence. From the fourth century BCE the Nabataeans, an Arab trading people, established a wealthy caravan kingdom centred on Petra that grew rich on incense and spice routes before being annexed by Rome in 106 CE as the province of Arabia Petraea. Roman and later Byzantine rule left a dense legacy of cities, including Jerash and Umm Qais, which were absorbed into the Islamic world after the decisive battle of Yarmouk in 636.

Under successive Muslim dynasties the territory passed from the Rashidun and Umayyad caliphates, whose desert palaces still dot the eastern steppe, to the Abbasids, the Fatimids, and the Crusader-era lordships of Oultrejourdain, before being recovered for Islam by Saladin in the late twelfth century. Mamluk and then Ottoman administration followed from 1516 onward, governing the area as part of the wider provinces of Damascus and Hejaz for four centuries. Ottoman rule ended during the First World War, when the Arab Revolt of 1916 to 1918, led by Sharif Hussein of Mecca and his sons of the Hashemite family, drove Ottoman forces from the region in cooperation with British arms.

In 1921 the British, holding a League of Nations mandate over Palestine, separated the territory east of the Jordan and installed Hussein's son Abdullah as ruler of the new Emirate of Transjordan. The emirate gained substantial autonomy through the 1928 Anglo-Transjordanian treaty and achieved full independence on 25 May 1946 as the Hashemite Kingdom of Jordan, with Abdullah I proclaimed king. Jordan participated in the 1948 Arab-Israeli war and afterward annexed the West Bank and East Jerusalem, a union formally dissolved in 1988. King Abdullah I was assassinated in 1951; after the brief reign of his son Talal, the throne passed in 1953 to Hussein bin Talal, whose long rule defined modern Jordanian politics.

Hussein navigated the loss of the West Bank in the 1967 Six-Day War, the 1970 confrontation with Palestinian armed factions known as Black September, and the gradual political opening of the late 1980s, which restored parliamentary elections in 1989. Jordan signed a peace treaty with Israel in 1994, becoming the second Arab state to do so, and developed close security and economic ties with the United States and the European Union while remaining within the Arab League. King Abdullah II succeeded his father in 1999 and oversaw cautious constitutional adjustments during and after the 2011 Arab Spring protests, alongside the absorption of large refugee populations from Iraq and Syria.

Jordan today is a constitutional monarchy in which the king retains substantial executive authority, governing alongside an appointed prime minister and cabinet and a bicameral National Assembly composed of an appointed Senate and an elected Chamber of Deputies.
