19th century, ascribes the destruction of Alodia to King Amara Dunqas; he was also allied with Abdallah Jammah. This attack is dated to the 9th century after the Hijra ( 1396–1494). Afterwards, Soba is said to have served as the capital of the Funj until the foundation of Sennar in 1504. The Tabaqat Dayfallah, a history of Sufism in Sudan ( 1700), briefly mentions that the Funj attacked and defeated the "kingdom of the Nuba" in 1504–1505. Legacy Historian Jay Spaulding proposes that the fall of Soba was not necessarily the end of Alodia. According to the Jewish traveler David Reubeni, who visited the country in 1523, there was still a "kingdom of Soba" on the eastern bank of the Blue Nile, although he explicitly noted Soba itself was in ruins. This matches the oral traditions from the Upper Blue Nile, which claim that Alodia survived Soba's fall and still existed along the Blue Nile. It had gradually retreated to the mountains of Fazughli in the Ethiopian-Sudanese borderlands, forming the kingdom of Fazughli. Recent excavations in western Ethiopia seem to confirm the theory of an Alodian migration. The Funj eventually conquered Fazughli in 1685 and its population, known as Hamaj, became a fundamental part of Sennar, eventually seizing power in 1761–1762. As recently as 1930 Hamaj villagers in the southern Gezira would swear by "Soba the home of my grandfathers and grandmothers which can make the stone float and the cotton ball sink". In 1504–1505 the Funj founded the Funj sultanate, incorporating Abdallah Jammah's domain, which, according to some traditions, happened after a battle where Amara Dunqas defeated him. The Funj maintained some medieval Nubian customs like the wearing of crowns with features resembling bovine horns, called taqiya umm qarnein, the shaving of the head of a king upon his coronation, and, according to Jay Spaulding, the custom of raising princes separately from their mothers, under strict confinement. The aftermath of Alodia's fall saw extensive Arabization, with the Nubians embracing the tribal system of the Arab migrants. Those living along the Nile between al Dabbah in the north and the confluence of the two Niles in the south were subsumed into the Ja'alin tribe. To the east, west and south of the Ja'alin the country was now dominated by tribes claiming a Juhaynah ancestry. In the area around Soba, the tribal Abdallab identity prevailed. The Nubian language was spoken in
