In 1516, the Ottoman Caliphate's forces conquered Mamluk territory. Agricultural villages in Transjordan witnessed a period of relative prosperity in the 16th century, but were later abandoned. Transjordan was of marginal importance to the Ottoman authorities. As a result, Ottoman presence was virtually absent and reduced to annual tax collection visits. More Arab Bedouin tribes moved into Transjordan from Syria and the Hejaz during the first three centuries of Ottoman rule, including the Adwan, the Bani Sakhr and the Howeitat. These tribes laid claims to different parts of the region, and with the absence of a meaningful Ottoman authority, Transjordan slid into a state of anarchy that continued till the 19th century. This led to a short-lived occupation by the Wahhabi forces (1803–1812), an ultra-orthodox Islamic movement that emerged in Najd (in modern-day Saudi Arabia). Ibrahim Pasha, son of the governor of the Egypt Eyalet under the request of the Ottoman sultan, rooted out the Wahhabis by 1818. In 1833 Ibrahim Pasha turned on the Ottomans and established his rule over the Levant. His oppressive policies led to the unsuccessful peasants' revolt in Palestine in 1834. Transjordanian cities of Al-Salt and Al-Karak were destroyed by Ibrahim Pasha's forces for harboring a peasants' revolt leader. Egyptian rule was forcibly ended in 1841, with Ottoman rule restored.
