Only after Ibrahim Pasha's campaign did the Ottoman Empire try to solidify its presence in the Syria Vilayet, which Transjordan was part of. A series of tax and land reforms (''Tanzimat'') in 1864 brought some prosperity back to agriculture and to abandoned villages; the end of virtually autonomy predictably provoked a backlash in other areas of Transjordan. Muslim Circassians and Chechens, fleeing Russian persecution, sought refuge in the Levant. In Transjordan and with Ottoman support, Circassians first settled in the long-abandoned vicinity of Amman in 1867, and later in the surrounding villages. After having established its administration, conscription and heavy taxation policies by the Ottoman authorities led to revolts in the areas it controlled. Transjordan's tribes in particular revolted during the Shoubak (1905) and the Karak Revolts (1910), which were brutally suppressed. The construction of the Hejaz Railway in 1908–stretching across the length of Transjordan and linking Mecca with Istanbul helped the population economically, as Transjordan became a stopover for pilgrims. However, increasing policies of Turkification and centralization adopted by the Ottoman Empire disenchanted the Arabs of the Levant.
