History
The north was settled long before the Romans. Amman was Rabbath Ammon, capital of the Ammonites, and the plateau around Karak and Dhiban was the kingdom of Moab, whose King Mesha recorded his victories on the Mesha Stele found at Dhiban in 1868. Under the Hellenistic and Roman empires, Amman became Philadelphia, and Gerasa (Jerash), Gadara (Umm Qais) and Pella joined the Decapolis, a league of Greek-speaking cities; Jerash grew rich on the trade that Rome's annexation of Nabataea in 106 AD brought through the region. Byzantine Christianity then covered Madaba and Mount Nebo with mosaic-floored churches.
After the Muslim victory over Byzantium at the Yarmouk River in 636, the Umayyad caliphs of Damascus built bathhouses, hunting lodges and caravan halts in the eastern desert, among them Qusayr Amra and Qasr Kharana. The Crusaders built Karak Castle in the 1140s to control the road from Damascus to Egypt; Saladin's forces took it in 1188, while his general had raised Ajloun Castle a few years earlier.
Under the Ottomans the area was a thinly held frontier until Circassian refugees resettled the ruins of Amman from 1878 and the Hejaz Railway arrived in the 1900s. Salt was the Ottoman administrative centre until Emir Abdullah made Amman the capital of Transjordan in 1921. Palestinian refugees in 1948 and 1967, fighting between the army and Palestinian armed groups in 1970, and later the arrival of Iraqis and Syrians, turned Amman into a large city.
