Adharbayjan in the context of "Talysh people"

Maslama ibn Abd al-Malik (fl. 705 – 24 December 738) was an Umayyad prince and one of the most prominent Arab generals of the early decades of the 8th century, leading several campaigns against the Byzantine Empire and the Khazar Khaganate. He achieved great fame especially for leading the last Arab siege of the Byzantine capital Constantinople.

He launched his military career leading the annual summer raids against the Byzantines in Anatolia. By 709, he was governor over Qinnasrin (northern Syria), the Jazira (Upper Mesopotamia), Armenia, and Adharbayjan, giving him control over the Caliphate's northern frontier. From this position, he launched the first Arab expeditions against the Khazars across the Caucasus. Maslama's brother, Caliph Sulayman, appointed him to lead the campaign to capture Constantinople in 715, but it ended in disaster for the Arabs and he was ordered to withdraw by Sulayman's successor, Umar II, in 718.

Al-Jazira (Arabic: الجزيرة), also known as Jazirat Aqur or Iqlim Aqur, was a province of the Rashidun, Umayyad and Abbasid Caliphates, spanning at minimum most of Upper Mesopotamia (al-Jazira proper), divided between the districts of Diyar Bakr, Diyar Rabi'a and Diyar Mudar, and at times including Mosul, Arminiya and Adharbayjan as sub-provinces.

Following its conquest by the Muslim Arabs in 639/40, it became an administrative unit attached to the larger district of Jund Hims. It was separated from Hims during the reigns of caliphs Mu'awiya I or Yazid I and came under the jurisdiction of Jund Qinnasrin. It was made its own province in 692 by Caliph Abd al-Malik. After 702, it frequently came to span the key districts of Arminiya and Adharbayjan along the Caliphate's northern frontier, making it a super-province. The predominance of Arabs from the Qays/Mudar and Rabi'a groups made it a major recruitment pool of tribesmen for the Umayyad armies and the troops of the Jazira played a key military role under the Umayyad caliphs in the 8th century, peaking under the last Umayyad caliph, Marwan II (r. 744–750), until the toppling of the Umayyads by the Abbasids in 750.

The battles of Madhar and Harura (Arabic transliteration: Yawm Madhār and Yawm Ḥarūrāʾ) successively took place in the latter half of 686 in the environs of Basra and Kufa, respectively, both in southern Iraq. The battles were fought between the forces of Mus'ab ibn al-Zubayr, the governor of Basra on behalf of his brother Caliph Abd Allah ibn al-Zubayr who later joined the Battle as re-inforcement(r. 683–692), and Mukhtar al-Thaqafi, the pro-Alid ruler of Kufa. They ended with the latter's decisive defeat and the slaying of most of his commanders. In the immediate aftermath, Mus'ab besieged and killed Mukhtar in Kufa, sanctioned the killing of thousands of his sympathizers in the city, and annexed Kufa and its dependencies, i.e. the Sawad (Lower Mesopotamia) and Jibal (northwestern Iran). Ibrahim ibn al-Ashtar, Mukhtar's governor over Mosul and its dependencies, i.e. the Jazira (Upper Mesopotamia), Adharbayjan, and Arminiya, afterward defected to Mus'ab. In effect, all of Iraq came under Zubayrid authority as a result of Mus'ab's victory.

Jibāl (Arabic: جبال), also al-Jabal (Arabic: الجبل), was the name given by the Arabs to a region and province located in western Iran, under the Umayyad and Abbasid Caliphates.

Its name means "the Mountains", being the plural of jabal ("mountain, hill"), highlighting the region's mountainous nature in the Zagros. Between the 12th and 14th centuries, the name Jibal was progressively abandoned, and it came to be mistakenly referred to as ʿIrāq ʿAjamī ("Persian Iraq") to distinguish it from "Arab Iraq" in Mesopotamia. The region never had any precisely defined boundaries, but was held to be bounded by the Maranjab Desert in the east, by Fars and Khuzistan in the south, by Iraq in the south-west and west, by Adharbayjan in the north-west and by the Alborz Mountains in the north, making it roughly coterminous with the ancient country of Media.
