Motamid had appointed his son al-Mofawwid as successor to the Caliphate, and after him his brother Mowaffaq. When the latter died in the year 891, his son Aḅū ‘l-‘Abbās, al-Mo’taḍid (“he who seeks his support in God”), was put in his place. Next year Mofawwid was compelled to abdicate in favour of his cousin. Shortly after Motamid died, Rajab 279 (October 892). Not long before these events, the seat of the Caliphate had been restored to Bagdad.

16. Reign of Motadid.—Motadid may be called, after Mansūr, the most able and energetic of all the Abbasid rulers. He took good care of the finances, reformed the administration, was an excellent commander in war, and maintained order as far as possible. The Kharijites in Mesopotamia, who for many years had molested the government, were finally crushed with the aid of their former ally Ḥamdān, who became the founder of the well-known dynasty of the Ḥamdānites. The mighty house of Abū Dolaf in the south-west of Media, which had never ceased to encroach on the Caliphate, was put down. The governor of Azerbaijan and Armenia, belonging to the powerful Turkish house of the Sājids or Sājites, whose loyalty was always doubtful, planned an invasion of Syria and Egypt. Motadid frustrated it by a quick movement. The citizens of Tarsus who were involved in the plot were severely punished. The chief punishment, however, the burning of the fleet, was a very impolitic measure, as it strengthened the hands of the Byzantines.

Almost simultaneously with the rising of the negro slaves in Basra there arose in the province of Kūfa the celebrated sect of the Carmathians (q.v.), Fātimites[41] or Isma‘ilites. This powerful sect, which save for a difference of opinion would have joined the negro rising, remained outwardly quiet during Motamid’s reign, but under Motadid the government began to have misgivings about them. Abū Sa‘īd al-Jannābī, who had founded a Carmathian state in Bahrein, the north-eastern province of Arabia (actually called Laḥsā), which could become dangerous for the pilgrim road as well as for the commerce of Basra, in the year 900 routed an army sent against him by Motadid, and warned the caliph that it would be safer to let the Carmathians alone. In the same year the real chief of the sect, whose abode had been discovered by the caliph, fled from Salamia in Syria, where he lived, to Africa, and hid himself at Sijilmāsa (in Tafilalt) in the far west, whence he reappeared ten years later at Kairawan as the Mahdi, the first caliph of the Fatimites.[42]

Motadid died in Rabia II. a.h. 289 (March 902), leaving the Caliphate to his son al-Moktāfī billāh (“he who sufficeth himself in God”).

17. Reign of Moktafi.—Moktafi inherited his father’s intrepidity, and seems to have had high personal qualities, but his reign of six years was a constant struggle against the Carmathians in Syria, who defeated the Syrian and Egyptian troops, and conquered Damascus and other cities. Moktafi led his troops in person, and his general, Mahommed b. Suleimān, gained a signal victory. Three of their chiefs were taken and put to death. But, to avenge their defeat, they lay in wait for the great pilgrim caravan on its return from Mecca in the first days of 294 (906), and massacred 20,000 pilgrims, making an immense booty. This horrible crime raised the whole Moslem world against them. Zikrūya their chief was defeated at last and perished.

After the defeat of the Syrian Carmathians, Mahommed b. Suleimān was sent by the caliph to Egypt, where he overthrew the dominion of the Tūlūnids. ‘Īsā b. Mahommed al-Naushari was made governor in their stead (905).

The war with the Byzantines was conducted with great energy during the reign of Moktafi. In the year 905 the Greek general Andronicus took Marash, and penetrated as far as Haleb (Aleppo), but the Moslems were successful at sea, and in 907 captured Iconium, whilst Andronicus went over to the caliph’s side, so that the Byzantine emperor sent an embassy to Bagdad to ask for a truce and an exchange of prisoners.

18. Reign of Moqtadir.—The sudden death of Moktafi, Dhu‘l-qa‘da 295 (August 908), was a fatal blow to the prestige of the Caliphate, which had revived under the successive governments of Mowaffaq, Motadid and himself. The new caliph, al-Moqtadir billāh (“the powerful through God”), a brother of Moktafi, was only thirteen years of age when he ascended the throne. Owing to his extreme youth many of the leading men at Bagdad rebelled and swore allegiance to Abdallah, son of the former caliph Motazz, a man of excellent character and of great poetical gifts; but the party of the house of Motadid prevailed, and the rival caliph was put to death. Moqtadir, though not devoid of noble qualities, allowed himself to be governed by his mother and her ladies and eunuchs. He began by squandering the 15,000,000 dinars which were in the treasury when his brother died in largesses to his courtiers, who, however, merely increased their demands. His very able vizier, the noble and disinterested Ali b. ‘Īsā, tried to check this foolish expenditure, but his efforts were more than counterbalanced by the vizier Ibn abi‘l-Forāt and the court. The most shameless bribery and the robbery of the well-to-do went together with the most extravagant luxury. The twenty-four years of Moqtadir’s reign are a period of rapid decay. The most important event in the reign was the foundation of the Fātimite dynasty, which reigned first in the Maghrib and then in Egypt for nearly three centuries (see [Fatimites] and [Egypt]: History, “Mahommedan”).

Far more dangerous, however, for the Caliphate of Bagdad at the time were the Carmathians of Bahrein, then guided by Abu Ṭāhir, the son of Abu Sa‘īd Jannābi. In 311 (a.d. 923) they took and ransacked Basra; in the first month of the following year the great pilgrim caravan on its return from Mecca was overpowered; 2500 men perished, while an even larger number were made prisoners and brought to Lahsā, the residence of the Carmathian princes, together with an immense booty. The caravan which left Bagdad towards the end of this year returned in all haste before it had covered a third of the way. Then Kufa underwent the fate that had befallen Basra. In 313 (a.d. 926) the caravan was allowed to pass on payment of a large sum of money. The government of Bagdad resolved to crush the Carmathians, but a large army was utterly defeated by Abu Ṭāhir in 315 (927), and Bagdad was seriously threatened. Next year Mecca was taken and plundered; even the sacred Black Stone was transported to Lahsā, where it remained till 339 (950), when by the express order of the Imām, the Fātimite caliph, it was restored to the Ka‘ba.

In 317 (929) a conspiracy was formed to dethrone Moqtadir, to which Mūnis, the chief commander of the army, at first assented, irritated by false reports. Very soon he withdrew, and though he could not prevent the plundering of the palace, and the proclamation as caliph of another son of Motadid with the title al-Qāhir billāh (“the victorious through God”), he rescued Moqtadir and his mother, and at the same time his imprisoned friend Ali b. ‘Īsā, and brought them to his own house. A few days later, a counter-revolution took place; the leaders of the revolt were killed, and Moqtadir, against his wish, was replaced on the throne. In 320 (a.d. 932) Mūnis, discovering a court intrigue against him, set out for Mosul, expecting that the Hamdānids, who owed to him their power, would join him. Instead of doing this, they opposed him with a numerous army, but were defeated. Mūnis took Mosul, and having received reinforcements from all parts, marched against Bagdad. The caliph, who wished nothing more than to be reconciled to his old faithful servant, was forced to take arms against him, and fell in battle Shawwāl 320 (October 932), at the age of 38 years. His reign, which lasted almost twenty-five years, was in all respects injurious to the empire.
