Diyar Rabi'a

Diyar Rabi'a (Arabic: دِيَارُ رَبِيعَةَ, romanized: Diyār Rabīʿa, lit.

According to the medieval geographer al-Baladhuri, all three provinces were named after the main Arab tribes that were settled there by Mu'awiya in the course of the Muslim conquests of the 7th century.

Diyar Rabi'a encompasses the upper reaches of the river Khabur and its tributaries, i.e. the regions of Tur Abdin and Beth Arabaye, as well as both shores of the river Tigris from the vicinity of Jazirat ibn Umar in the north to the boundary with Iraq in the area of Tikrit in the south, including the lower reaches of the Upper Zab and Lower Zab.

The main city of the province was Mosul (Arabic al-Mawsil), with other important urban centres at Balad, Jazirat ibn Umar, al-Sinn, Barqa'id, Sinjar, Nasibin, Mardin and Ra's al-'Ayn.

The Hamdanid emirate was terminated by the Buyids in 980, and the province passed under the control of the Uqaylids, who held it until the Seljuq conquest in the late 11th century.
