It is first mentioned by the 10th century geographer al-
Ya'qubi (fl. 872 A.D.), who gives the following short but valuable description; :"It is a spacious, important country. The capital of the kingdom is Kubar. The Arabs still go to it for trading and they (the Ethiopians) have mighty cities, and their coast is
Dahlak. As to the kings in the land of
al-Habasha they are under the control of the great king (the Najashi) to whom they show obedience and pay taxes. The Najashi is of the Jacobite Christian faith." The historian
al-Masudi refers to Kubar in his
The Meadows of Gold, describing it as a "great city" and the "residence of the Najashi". In a similar context, in his
Akhbar al-zaman, the same al-Masudi calls the Ethiopian capital "Kufar" or "Kafer". In the Arabic works of the 13th and 14th century, Kubar is still mentioned as being the capital of Ethiopia. Arab historian
Ibn Khaldun refers to it in his
Kitab al-ibar. ==Location==
