In A.H. 116 (734) Junayd, in spite of his great services, was dismissed from his post by the Caliph for having married the daughter of Yezīd ibn Muhallab, and `Āsim ibn `Abdullah was appointed in his stead. He died of dropsy before his successor reached Merv. By his cruelty and injustice to all who had held office under Junayd, `Āsim incurred the bitter hatred of his people.

A certain Hārith ibn Surayj rose against him, took possession of many towns in Khorāsān, such as Merv er-Rūd, Balkh, and Bab-el-Abwāb, and gathered a crowd of soldiers of fortune to his banner by distributing amongst them the tribute levied from his acquisitions. `Āsim, failing to crush this revolt, was dismissed by the Caliph, and Asad el-Kasrī was reinstated in the governorship of Khorāsān.[160] Asad at once advanced against Hārith at the head of a large army, drove him to Turkestān, where he entered into league with the Khākān, who assigned him and his followers the town of Fārāb as a residence.

In A.H. 118 (736) Balkh became temporarily the Mohammedan capital of Central Asia. In the same year Asad planned a campaign into Khottal, but the Khākān took measures to forestall him. Asad’s advance column was taken completely by surprise, and his camp and harem were captured. A parley ensued without result, after which he returned to Balkh, while the Khākān again withdrew to Tokhāristān. But in the following spring Asad attacked and completely routed the Khākān and rescued all the Moslem provinces.[161] The Turk fled back to Tokhāristān, and shortly afterwards, while on his way to attack Samarkand, he was waylaid and killed by a rebellious follower.


CHAPTER X
Nasr ibn Sayyār and Abū Muslim

In A.H. 120 (737)[162] Asad died, and was succeeded by Nasr ibn Sayyār, one of the ablest rulers and generals ever sent to the East in Mohammedan times. He was as generous as he was strong, and seems to have won the affection of those under him. During the nine years of his governorship his position was by no means an easy one, for he had to contend with the growing influence of the `Abbāsid faction,[163] and to support, with a loyalty worthy of a better cause, the last degenerate representatives of the house of Umayya. His first care on assuming the supreme command was to subjugate the Khākān of the Turks, whose name was Kūrsūl, against whom he led three successive expeditions. The first two seem to have been without result, but in the last, which was directed against Shāsh, the Khākān fell into his hands and was put to death.[164]

In the same year Nasr renewed his attempt to subject Shāsh to the Moslem yoke. The campaign was a bloodless one. He received the submission of Ushrūsana, and concluded an advantageous peace with the king of Shāsh.[165] He thereupon appointed a Mohammedan governor of Farghāna.

In the year A.H. 123 (740) this judicious ruler established order throughout Transoxiana, Khorāsān, and Farghāna.[166] But he had other difficulties to meet which were not of his own making. The star of the Umayyads was in the descendent, and the `Abbāsid party were daily adding to the number of their adherents. And, apart from dynastic struggles, the whole of Islām was rent with the dissensions of the rival sects of the Khārijites and the Shi`ites. The sectarian zeal of the latter, which to this day remains the cause of bitter discord in the realm of Islām, began now to make itself felt in Persia and in Central Asia.

In A.H. 125 (742) Hishām, the last Umayyad Caliph of any distinction, died. The dynasty lasted seven years longer, and in that short period no less than four Caliphs[167] attempted to restore the fading glory of their house. While such disorders reigned at headquarters there was small hope of quelling sedition in the outlying provinces. The `Abbāsid pretender, Ibrāhīm, thanks to the efforts of his father’s[168] emissaries, had now a powerful and rapidly increasing faction in Merv. But Nasr still held command in Khorāsān, and his personal influence was still great enough to avert open rebellion. It failed; and the fierce tribal jealousy which always smouldered in Arab breasts burst into civil war. The two rival factions were the Yemenites and the Modharites. Nasr ibn Sayyār belonged to the tribe of Modhar, and bestowed the highest offices on his clansmen. In fact, all the towns of Khorāsān were governed by members of one or the other of the three principal branches of the tribe, Asad, Temīm, or Kināna. Now, there was a man of the tribe of Azd called, after his birthplace, Juday` El-Kirmānī, who, before the promotion of Nasr, had held a higher position, and retained some authority among his own people. To him came the Beni Rabī`a with complaints of the partiality of Nasr. He promised his intercession with the governor. On attempting remonstrance he raised Nasr’s ire, and was cast into prison, whence escaping[169] he rejoined his own people. All efforts at reconciliation proving fruitless, the rival parties had recourse to armed strength. In A.H. 127 (744) Hārith ibn Surayj, who was permitted to return to Khorāsān from his captivity in Fārāb, set up his standard at Merv, and, gathering many followers around it, openly revolted against Nasr. In the following year Nasr called upon him to swear allegiance to the Caliph Merwān, but Hārith refused, and boasted that he was “the man with the black flag”[170] who was to overthrow the Umayyad dynasty. Hostilities thereupon commenced between Nasr and Hārith, in which the latter was worsted. He fled to the camp of El-Kirmānī, whom Nasr had meanwhile been vainly endeavouring to conciliate.

Their combined forces now marched against Nasr, whom they defeated in a pitched battle. Nasr fled to Nīshāpūr, while the allies occupied Merv, where, however, dissensions arose between them which cost Hārith his life, A.H. 128 (745).[171]
