The Kingdom of Alodia and Its Capital Soba — The Longest-Lived Christian Nubian Kingdom
The Kingdom of Alodia, also known as Alwa, arose in what is now central Sudan after the fall of the ancient Kingdom of Kush around AD 350. It was first mentioned in historical records in 569, and it was the last of the three Nubian kingdoms to embrace Christianity, in 580, after Nobatia in the north, whose capital was Faras, and Makuria in the centre, whose capital was Old Dongola. The heart of the kingdom extended across the fertile Gezira land between the White Nile and the Blue Nile, and its furthest known sites to the south reached close to Sennar, on the fringes of the Ethiopian highlands.
The capital, Soba, stood on the right bank of the Blue Nile, about 19 kilometres south of the centre of present-day Khartoum, near the confluence of the two Niles. Researchers have estimated its area at its peak at about 240 to 275 hectares, making it one of the largest archaeological sites in Sudan. The traveller and diplomat Ibn Salim al-Aswani described it in the tenth century AD as a city of spacious dwellings, churches adorned with gold, gardens, large monasteries and a quarter for Arab merchants, and he considered Alodia the strongest of the Nubian kingdoms in his time.
Alodia probably reached its peak between the ninth and twelfth centuries AD, when records indicate that it surpassed its neighbour Makuria in size, military strength and economic prosperity, while close family ties remained between the two kingdoms. It was ruled by a strong king assisted by provincial governors whom he appointed, and Soba flourished as a trading centre reached by goods from Makuria, the Middle East, West Africa, India and even China. Writing also flourished there in the Nubian and Greek languages, with Greek being the language of the church liturgy linked to the Coptic Patriarchate of Alexandria.
Excavations at Soba, from the work of Peter Shinnie in the early 1950s and then the excavations of Derek Welsby and Charles Daniels in the 1980s and 1990s, have revealed churches, a palace, cemeteries and many mounds of red-brick ruins left by huge buildings. Yet only about one per cent of the city's area has been studied in detail to this day, which prompted a multidisciplinary research project led by the Polish Centre of Mediterranean Archaeology at the University of Warsaw, with Sudanese and Scottish partners, to resume survey and excavation since 2019 to document what remains of it and protect it.
Alodia's decline began in the twelfth century and accelerated in the thirteenth, for reasons researchers believe included invasions from the south, drought and the shifting of trade routes, followed by increasing Arab migrations into the upper Nile Valley. The Funj Chronicle and Abdallab traditions record that Soba was destroyed in 1504, so the kingdom effectively ended around AD 1500 after a life of nearly a thousand years, and the Sultanate of Sennar later arose on the ruins of the region. In the nineteenth century much of Soba's red brick was carried away to build the new Khartoum, and urban sprawl today threatens what remains of the site, as modern buildings have covered about half of its original area.
