Abu Muslim Abd al-Rahman ibn Muslim al-Khurasani or Behzādān Pour Vandād Hormozd born 718/19 or 723/27, died in 755), was a Persian general in service of the Abbasid dynasty, who led the Abbasid Revolution that toppled the Umayyad dynasty.
Greater Khorāsān, or Khorāsān, is a historical eastern region in the Iranian Plateau between Western and Central Asia. The name Khorāsān is Persian and means "where the sun arrives from" or "the Eastern Province". The name was first given to the eastern province of Persia during the Sasanian Empire and was used from the late Middle Ages in distinction to neighbouring Transoxiana. Greater Khorasan is today sometimes used to distinguish the larger historical region from the former Khorasan Province of Iran (1906–2004), which roughly encompassed the western half of the historical Greater Khorasan.
Naṣr ibn Sayyār al-Lāythi al-Kināni was an Arab general and the last Umayyad governor of Khurasan in 738–748. Nasr played a distinguished role in the wars against the Turgesh, although he failed to decisively confront the rebellion of al-Harith ibn Surayj in its early stages. Although respected as a soldier and a statesman, he owed his appointment as governor more to his obscure tribal background, which rendered him dependent on the Caliph. His tenure was nevertheless successful, as Nasr introduced long-overdue tax reforms that alleviated social tension and largely restored and stabilized Umayyad control in Transoxiana, which had been greatly reduced under the Turgesh onslaught. His last years were occupied by inter-tribal rivalries and uprisings, however, as the Caliphate itself descended into a period of civil war. In 746 Nasr was driven from his capital by Ibn Surayj and Juday al-Kirmani, but returned after the latter fell out among themselves, resulting in Ibn Surayj's death. Preoccupied with this conflict, Nasr was unable to stop the outbreak and spread of the Abbasid Revolution, whose leader, Abu Muslim, exploited the situation to his advantage. Evicted from his province in early 748, he fled to Persia pursued by the Abbasid forces, where he died on 9 December 748.
Qahtaba ibn Shabib al-Ta'i was a follower of the Abbasids from Khurasan who played a leading role in the Abbasid Revolution against the Umayyad Caliphate.
The Abbasid Revolution, also called the Movement of the Men of the Black Raiment, was the overthrow of the Umayyad Caliphate, the second of the four major Caliphates in early Islamic history, by the third, the Abbasid Caliphate. Coming to power three decades after the death of the Islamic prophet Muhammad and immediately after the Rashidun Caliphate, the Umayyads were an Arab empire ruling over a population which was overwhelmingly non-Arab. Non-Arabs were treated as second-class citizens regardless of whether or not they converted to Islam, and this discontent cutting across faiths and ethnicities ultimately led to the Umayyads' overthrow. The Abbasid family claimed to have descended from al-Abbas, an uncle of Muhammad.
Al-Harith ibn Surayj was an Arab leader of a large-scale social rebellion against the Umayyad Caliphate in Khurasan and Transoxiana. Harith's rebellion began in 734 and represented the grievances of both the local Arab settlers as well as the native Iranian converts, who were not recognized as equal to the Arab Muslims, against the Umayyad regime. Harith based his revolt on religious grounds and won over a large part of both the Arab settlers and the native population, but failed twice to capture the provincial capital of Marw. The rebellion was finally suppressed by Asad ibn Abdallah al-Qasri in 736. Along with a few supporters, Harith escaped capture and allied himself with the heathen Türgesh. Harith accompanied the Türgesh qaghan Suluk in his invasion deep into Arab-held territory, which was decisively beaten back in the Battle of Kharistan in 737. With Türgesh power collapsing thereafter, Harith remained in Transoxiana supported by the native princes. Asad's successor, Nasr ibn Sayyar, campaigned against Harith and his native supporters, but eventually, hoping to use him to bolster his position in the Arab inter-tribal rivalries, Nasr secured for Harith a pardon from the Caliph. Harith returned to Marw in 745. Soon however he raised a sizeable armed force and challenged Nasr's authority, until he was killed in a clash with his ally Juday al-Kirmani in 746. His revolt weakened Arab power in Central Asia and facilitated the beginning of the Abbasid Revolution that would overthrow the Umayyads.
The Muslim conquest of Khorasan was the last phase of the heavy war between the Rashidun caliphate against the Sassanid Empire.
