Al-Tabari records that al-Wathiq was of medium height, handsome and well-built. He was fair with a ruddy complexion, commonly associated with noble descent. His left eye was paralyzed with a white fleck, which reportedly lent his gaze a stern aspect. When al-Mu'tasim died on 5 January 842, al-Wathiq succeeded him without opposition. Inheriting a full treasury, the new caliph made generous donations to the common people, especially in Baghdad and the Islamic holy cities of Mecca and
Medina. Al-Wathiq sent his mother, Qaratis, accompanied by his brother Ja'far (the future caliph
al-Mutawakkil), to head the
pilgrimage in 842. Qaratis died on the way at
al-Hirah on 16 August 842, and was buried in
Kufa.
Ruling elites Al-Wathiq's reign was short and is generally considered to have been essentially a continuation of al-Mu'tasim's own, as the government continued to be led by men that had been raised to power by al-Mu'tasim: the Turkic military commanders
Itakh,
Wasif, and
Ashinas, the
vizier,
Muhammad ibn al-Zayyat, and the chief (judge),
Ahmad ibn Abi Duwad. These men had been personally loyal to al-Mu'tasim, but were not similarly bound to al-Wathiq; in practice, according to Turner, this narrow circle "controlled the levers of power and thus the Caliph's independence". In a gesture likely aimed at cementing an alliance between the caliph and his most powerful commander, al-Wathiq bestowed a crown on Ashinas in June/July 843, and on the occasion invested him with sweeping authority over the western provinces, from Samarra to the
Maghreb—an act which the 15th-century Egyptian scholar
al-Suyuti considered as the first occasion when royal power () was delegated by a caliph to a subject. Ashinas died in 844, and Itakh succeeded him in his rank as commander-in-chief and in his over-governorship of the western provinces. The new caliph also engaged in much construction in Samarra, which went a long way towards making the caliphal residence a proper city, with markets and a port adequate to its needs. This made Samarra not only more comfortable for its inhabitants but also made investment in property there economically attractive—both major considerations for the Abbasid elites and the military, who had been forced to relocate to the new capital by al-Mu'tasim. However, in 843/44, the Caliph—allegedly at the instigation of the vizier Ibn al-Zayyat, or, according to a story reported by al-Tabari, inspired by the downfall of the
Barmakids under Harun al-Rashid—arrested, tortured, and imposed heavy fines on several of the secretaries in the central government, in an effort to raise money to pay the Turkic troops. The measure was at the same time possibly aimed at driving a wedge between civilian and military elites, or at reducing the power of the leading Turkic commanders, such as Itakh and Ashinas, since most of the secretaries arrested and forced to pay were in their service.
Suppression of rebellions and its provinces, Already during the last months of al-Mu'tasim's life, a large-scale revolt had erupted in
Palestine under a certain
al-Mubarqa. Al-Mu'tasim sent the general
Raja ibn Ayyub al-Hidari to confront the rebels. When al-Wathiq came to power, he dispatched al-Hidari against
Ibn Bayhas, who led a
Qaysi tribal revolt around
Damascus. The exact relationship of this uprising with the revolt of al-Mubarqa is unclear. Taking advantage of the dissensions among the tribesmen, al-Hidari quickly defeated Ibn Bayhas, and then turned south and confronted al-Mubarqa's forces near
Ramla. The battle was a decisive victory for the government army, with al-Mubarqa taken prisoner and brought to Samarra, where he was thrown into prison and never heard of again. Upon coming to the throne, al-Wathiq appointed
Khalid ibn Yazid al-Shaybani as governor of the restive province of
Armenia. At the head of a large army, Khalid defeated the opposition of the local Muslim and Christian princes at the Battle of Kawakert. Khalid died soon after, but his son,
Muhammad al-Shaybani, succeeded him in office and continued his father's task. In spring 845, another tribal rebellion broke out. A local tribe, the
Banu Sulaym, had become embroiled in a conflict with the tribes of
Banu Kinanah and
Bahilah around Medina, resulting in bloody clashes in February/March 845. The local governor,
Salih ibn Ali, sent an army against them comprising regular troops as well as citizens of Medina, but, the Sulaym were victorious and proceeded to loot the environs of the two holy cities. As a result, in May al-Wathiq charged one of his Turkic generals,
Bugha al-Kabir, to handle the affair. Accompanied by professional troops from the , Turkic, and guard regiments, Bugha defeated the Sulaym and forced them to surrender. In early autumn, he also forced the
Banu Hilal to submit. Bugha's troops took many prisoners, some 1,300 in total who were held in Medina. They tried to escape, but were thwarted by the Medinese, and most were killed in the process. In the meantime, Bugha used the opportunity to intimidate the other Bedouin tribes of the region, and marched to confront the
Banu Fazara and the
Banu Murra. The tribes fled before his advance, with many submitting, and others fleeing to
al-Balqa. Bugha then subdued the
Banu Kilab, taking some 1,300 of them as prisoners back to Medina in May 846. A minor
Kharijite uprising in 845/6 occurred in
Diyar Rabi'a under a certain Muhammad ibn Abdallah al-Tha'labi (or Muhammad ibn Amr), but was easily suppressed by the governor of
Mosul. In the same year, the general Wasif suppressed restive
Kurdish tribes in
Isfahan,
Jibal and
Fars. In September 846, al-Wathiq sent Bugha al-Kabir to stop the depredations of the
Banu Numayr in
Yamamah. On 4 February 847, Bugha fought a major engagement against about 3,000 Numayris at the watering place of Batn al-Sirr. At first he was hard pressed, and his forces almost disintegrated. Then some troops he had out raiding the Numayris' horses returned, fell upon the forces attacking Bugha and completely routed them. According to one report, up to 1,500 Numayris were killed. Bugha spent a few months pacifying the region, issuing writs of safe-passage to those who submitted and pursuing the rest, before he returned to
Basra in June/July 847. Over 2,200 Bedouin from various tribes were brought captive with him.
Mu'tazilism and the abortive coup of al-Khuza'i and events associated with it Like his father, al-Wathiq was an ardent
Mu'tazilite—the sources agree that he was strongly influenced by the chief , Ibn Abi Duwad—but also, like his father, maintained good relations with the
Alids. In the third year of his caliphate, al-Wathiq revived the inquisition (), sending officials to question jurists on their views on the controversial topic of the
createdness of the Quran. Al-Wathiq supported the Mu'tazili view that the Quran was created and not eternal, and hence fell within the authority of a God-guided
imam (i.e., the caliph) to interpret according to the changing circumstances. Even during a
prisoner exchange held with the
Byzantine Empire in 845, the ransomed Muslim prisoners were questioned on their opinions regarding the topic, with those giving unsatisfactory answers reportedly left to remain in captivity. Thus
Ahmad ibn Hanbal, the founder of the
Hanbali school of jurisprudence, who opposed the Mu'tazili doctrine, was forced to cease his teachings and only resumed them after al-Wathiq's death. In 846, a well-respected notable,
Ahmad ibn Nasr ibn Malik al-Khuza'i, a descendant of one of the original missionaries of the
Abbasid Revolution, launched a plot in Baghdad to overthrow al-Wathiq, his Turkic commanders, and the Mu'tazilite doctrines. His followers distributed money to the people, and the date for the uprising was scheduled for the night of 4/5 April 846. However, according to al-Tabari, those who were supposed to sound a drum as the signal to rise got drunk and did so a day early, and there was no response.
Khatib al-Baghdadi on the other hand reports simply that an informer gave the plot away to the authorities. The deputy governor of the city,
Muhammad ibn Ibrahim—the governor, his brother
Ishaq, was absent—inquired on the event, and the conspiracy was revealed. Al-Khuza'i and his followers were arrested and brought before al-Wathiq at Samarra. The Caliph interrogated al-Khuza'i publicly, though more on the thorny theological issue of the createdness of the Quran rather than on the actual rebellion. Ahmad's answers enraged al-Wathiq so much, that the Caliph took al-Samsamah, a famous sword of the
pre-Islamic period, and personally joined in the execution of Ahmad, along with the Turks
Bugha al-Sharabi and
Sima al-Dimashqi. Ahmad's corpse was publicly displayed next to the
gibbet of Babak in Baghdad, while twenty of his followers were thrown into prison. The same year there was a break-in at the public treasury () in Samarra. Thieves made off with 42,000 silver
dirhams and a small amount of
gold dinars. The (chief of security),
Yazid al-Huwani, a deputy of Itakh, pursued and caught them. Turner points out that this episode may provide some premonition of the
crisis to erupt in later decades: security even at the main palace was lax, and, based on the thieves' loot, the treasury appears to have been almost empty at the time.
War with the Byzantine Empire In 838 al-Mu'tasim had scored a major victory against the Abbasid Caliphate's perennial foe, the Byzantine Empire, with the celebrated sack of Amorion. This success was not followed up, and warfare reverted to the usual raids and counter-raids along the border. According to Byzantine sources, at the time of his death in 842, al-Mu'tasim was preparing yet another large-scale invasion, but the great fleet he had prepared to assault Constantinople perished in a storm off
Cape Chelidonia a few months later. This event is not reported in Muslim sources. Following al-Mu'tasim's death, the Byzantine regent
Theoktistos attempted to reconquer the
Emirate of Crete, an Abbasid vassal, but the campaign ended in disaster. In 844, an army from the border emirates of
Qaliqala and
Tarsus, led by Abu Sa'id, and possibly the emir of
Malatya Umar al-Aqta, raided deep into Byzantine
Asia Minor and reached as far as the shore of the
Bosporus. The Muslims then defeated Theoktistos at the
Battle of Mauropotamos, aided by the defection of senior Byzantine officers. At around the same time, the
Paulicians, a sect persecuted as heretical in Byzantium, defected to the Arabs under their leader
Karbeas. They founded a small principality on the Abbasid–Byzantine frontier, centred on the fortress of
Tephrike, and henceforth joined the Arabs in their attacks on Byzantine territory. In 845, a Byzantine embassy arrived at the caliphal court to negotiate about a prisoner exchange. It was held in September of the same year under the auspices of
Yazaman al-Khadim, and somewhere between 3,500 and 4,600 Muslims were ransomed. In March of the same year, however,
42 officers taken captive at Amorion were executed at Samarra, after refusing to convert to Islam. After the truce arranged for the exchange expired, the Abbasid governor of Tarsus, Ahmad ibn Sa'id ibn Salm, led a winter raid with 7,000 men. It failed disastrously, with 500 men dying of cold or drowning, and 200 taken prisoner. After this, the Arab-Byzantine frontier remained quiet for six years. Only in the west did the Abbasids'
Aghlabid clients continue their gradual
conquest of Byzantine
Sicily, capturing
Messina (842/43),
Modica (845), and
Leontini (846). In 845/46, the Aghlabids captured
Miseno near
Naples in mainland Italy, and in the next year their ships appeared in the
Tiber River and their crews
raided the environs of Rome. ==Death and succession==
