  In 1504 the Funj are recorded to have founded the Kingdom of Sennar, in which Abdallah Jamma's realm was incorporated. By 1523, when Jewish traveller David Reubeni visited Sudan, the Funj state already extended as far north as Dongola. Meanwhile, Islam began to be preached on the Nile by Sufi holy men who settled there in the 15th and 16th centuries and by David Reubeni's visit king Amara Dunqas, previously a Pagan or nominal Christian, was recorded to be Muslim. However, the Funj would retain un-Islamic customs like the divine kingship or the consumption of alcohol until the 18th century. Sudanese folk Islam preserved many rituals stemming from Christian traditions until the recent past.
  
  Soon the Funj came in conflict with the Ottomans, who had occupied Suakin c. 1526 and eventually pushed south along the Nile, reaching the third Nile cataract area in 1583/1584. A subsequent Ottoman attempt to capture Dongola was repelled by the Funj in 1585. Afterwards, Hannik, located just south of the third cataract, would mark the border between the two states. The aftermath of the Ottoman invasion saw the attempted usurpation of Ajib, a minor king of northern Nubia. While the Funj eventually killed him in 1611/1612 his successors, the Abdallab, were granted to govern everything north of the confluence of Blue and White Niles with considerable autonomy.
  
  During the 17th century the Funj state reached its widest extent, but in the following century it began to decline. A coup in 1718 brought a dynastic change, while another one in 1761–1762 resulted in the Hamaj Regency, where the Hamaj (a people from the Ethiopian borderlands) effectively ruled while the Funj sultans were their mere puppets. Shortly afterwards the sultanate began to fragment; by the early 19th century it was essentially restricted to the Gezira.
  
  The coup of 1718 kicked off a policy of pursuing a more orthodox Islam, which in turn promoted the Arabisation of the state. To legitimise their rule over their Arab subjects the Funj began to propagate an Umayyad descend. North of the confluence of the Blue and White Niles, as far downstream as Al Dabbah, the Nubians adopted the tribal identity of the Arab Jaalin. Until the 19th century Arabic had succeeded in becoming the dominant language of central riverine Sudan and most of Kordofan.
  
  West of the Nile, in Darfur, the Islamic period saw at first the rise of the Tunjur kingdom, which replaced the old Daju kingdom in the 15th century and extended as far west as Wadai. The Tunjur people were probably Arabised Berbers and, their ruling elite at least, Muslims. In the 17th century the Tunjur were driven from power by the Fur Keira sultanate. The Keira state, nominally Muslim since the reign of Sulayman Solong (r. c. 1660–1680), was initially a small kingdom in northern Jebel Marra, but expanded west- and northwards in the early 18th century and eastwards under the rule of Muhammad Tayrab (r. 1751–1786), peaking in the conquest of Kordofan in 1785. The apogee of this empire, now roughly the size of present-day Nigeria, would last until 1821.
