On the turn of the fifth century, the Blemmyes established a short-lived state in Upper Egypt and Lower Nubia, probably centered around Talmis (Kalabsha), but before 450 they were already driven out of the Nile Valley by the Nobatians. The latter eventually founded a kingdom on their own, Nobatia. By the 6th century there were in total three Nubian kingdoms: Nobatia in the north, which had its capital at Pachoras (Faras); the central kingdom, Makuria centred at Tungul (Old Dongola), about south of modern Dongola; and Alodia, in the heartland of the old Kushitic kingdom, which had its capital at Soba (now a suburb of modern-day Khartoum). Still in the sixth century they converted to Christianity. In the seventh century, probably at some point between 628 and 642, Nobatia was incorporated into Makuria.
