Ahmad ibn Ziyadat Allah ibn Qurhub

Last updated June 11, 2023

Ahmad ibn Ziyadat Allah ibn Qurhub, commonly known simply as Ibn Qurhub, ruled Sicily in rebellion against the Fatimid Caliphate, from 913 to 916. He launched raids against the Byzantine Empire in southern Italy and against the shores of Fatimid Ifriqiya, but was deposed and handed over to the Fatimids, who executed him and his followers in July 916.

Origin and early career

Ahmad hailed from Sicily,^[1] whose gradual conquest from the Byzantine Empire had been started by the Aghlabids in the 820s. The process had ended with the conquest of Taormina in 902, but had left some Byzantine strongholds in the mountainous northeast of the island (the Val Demone) as well as across the Strait of Messina in Calabria.^[2]

Ahmad ibn Qurhub's patronymics indicate a relationship with Uthman ibn Qurhub, who had been governor of the island in the 830s, and with a Muhammad ibn Qurhub, a military commander who had begun the siege that led to the capture of Syracuse in 878. This Muhammad may have been Ahmad's father.^[3]

Ahmad had served as Aghlabid governor of Tripoli just before the overthrow of the Aghlabids and the establishment of the Fatimid Caliphate in 909.^[1]

Rebellion

Soon after its establishment, the Fatimid regime in Ifriqiya sent its own governors to the island. However, the local Sicilian army, which was used to a broad autonomy in running its affairs, deposed the first governor, al-Hasan ibn Ahmad ibn Abi Khinzir, and drove away his successor, Ali ibn Umar al-Balawi.^[1] Rejecting the Fatimids' Shi'a regime, on 18 May 913 they raised Ibn Qurhub to power as governor of the island.^[1]^[4] Ibn Qurhub quickly rejected Fatimid suzerainty, and declared for the Fatimids' Sunni rival, the Abbasid caliph al-Muqtadir at Baghdad. The latter recognized Ibn Qurhub as emir of Sicily, and in token of this sent him a black banner, robes of honour, and a gold collar.^[4]^[5] As the historian Alex Metcalfe writes, the movement headed by Ibn Qurhub was peculiar to Sicily's circumstances. As a frontier society centred on jihad , "some form of caliphal authority [...] was essential for Sicily's legitimate existence as a political entity", but at the same time, it was a "specifically Sicilian attempt to free itself from colonial rule from Ifriqiya".^[3]

Already in spring/summer 913 he launched the customary annual raids against the Byzantine territories: his son Ali besieged Taormina, which had been reoccupied and rebuilt by the Byzantines, for two months without success,^[3]^[5] but Ibn Qurhub himself led a raid into Calabria, returning with considerable booty and many prisoners.^[4] A treaty between the Sicilian Arabs and the Byzantine strategos of Calabria, Eustathios, whereby the Byzantines agreed to give 22,000 gold coins annually in exchange for a truce, may have taken place soon after this.^[3]^[6]^[7] According to Heinz Halm, this truce may have led to dissatisfaction among the Sicilian troops with Ibn Qurhub and contributed to his eventual downfall, since it put an end to the profitable plundering raids against Byzantine territories.^[7]

In July 914, the Sicilian fleet, commanded by Ibn Qurhub's younger son Muhammad, raided the coasts of Ifriqiya. At Leptis Minor, the Sicilians caught a Fatimid naval squadron by surprise on 18 July: the Fatimid fleet was torched, and 600 prisoners were made. Among the latter was the former governor of Sicily, Ibn Abi Khinzir, who was executed.^[4]^[5] The Sicilians defeated a Fatimid army detachment sent to repel them, and proceeded south, sacking Sfax and reaching Tripoli in August 914. Only the presence of the Fatimid heir-designate, al-Qa'im bi-Amr Allah, who was then on his way to invade Egypt, deterred an attack on the city.^[5]

In the next year, however, a similar undertaking failed, and the Sicilian fleet was defeated by the Fatimids, possibly with Byzantine assistance.^[4]^[5] As a result, the Sicilians began to turn to the Fatimids, with the Berbers of Agrigento being the first to defect, and other cities following soon after.^[5] His support vanishing, Ibn Qurhub prepared to flee to al-Andalus, but on 14 July 916 he was captured by the Sicilians, who delivered him and his supporters to the Fatimid caliph al-Mahdi Billah in chains.^[4]^[5] Al-Mahdi brought them to his palace city at Raqqada, where they were lashed on the tomb of Ibn Abi Khinzir, mutilated, and publicly crucified.^[4]^[5]

Sicily was subdued by a Fatimid army under Abu Sa'id Musa ibn Ahmad al-Dayf, which besieged Palermo until March 917. The local troops were disarmed, and a Kutama garrison loyal to the Fatimids was installed, under the governor Salim ibn Asad ibn Abi Rashid.^[8] Nevertheless, the legacy of Ibn Qurhub on Sicily was remembered for some time: as late as 973, when Ibn Hawqal visited Palermo, he found one of the gates of the city walls named after him.^[9]

The Muslim conquest of Sicily began in June 827 and lasted until 902, when the last major Byzantine stronghold on the island, Taormina, fell. Isolated fortresses remained in Byzantine hands until 965, but the island was henceforth under Muslim rule until conquered in turn by the Normans in the 11th century.

The navy of the Fatimid Caliphate was one of the most developed early Muslim navies and a major military force in the central and eastern Mediterranean in the 10th–12th centuries. As with the dynasty it served, its history can be distinguished into two phases. The first period, from c. 909 to 969, when the Fatimids were based in Ifriqiya, and the second period, lasting until the end of the dynasty in 1171, when the Fatimids were based in Egypt. During the first period, the navy was employed mainly in the constant warfare with the Byzantine Empire in Sicily and southern Italy, where the Fatimids enjoyed mixed success, as well as in the initially unsuccessful attempts to conquer Egypt from the Abbasids and the brief clashes with the Umayyad Caliphate of Córdoba.

The Battle of the Straits was fought in early 965 between the fleets of the Byzantine Empire and the Fatimid Caliphate in the Straits of Messina. It resulted in a major Fatimid victory, and the final collapse of the attempt of Emperor Nikephoros II Phokas to recover Sicily from the Fatimids.

Al-Hasan ibn Ali ibn Abi al-Husayn al-Kalbi, known in Byzantine sources as Boulchasenes and Aboulchare (Ἀβουλχαρέ), was the first Kalbid Emir of Sicily. A member of an aristocratic family within the ruling circle of the Fatimid Caliphate, he helped suppress the great revolt of Abu Yazid in 943–947 and was sent as governor of Sicily from 948 until 953, when he returned to Ifriqiya. He was succeeded in Sicily by his son Ahmad ibn al-Hasan al-Kalbi, but led several campaigns in Sicily and southern Italy against the Byzantines in 955–958, as well as the raid against Almeria that sparked a brief conflict with the Caliphate of Córdoba in 955. He died at Palermo in 964, during another campaign against the Byzantines.

The first Fatimid invasion of Egypt occurred in 914–915, soon after the establishment of the Fatimid Caliphate in Ifriqiya in 909. The Fatimids launched an expedition east, against the Abbasid Caliphate, under the Berber General Habasa ibn Yusuf. Habasa succeeded in subduing the cities on the Libyan coast between Ifriqiya and Egypt, and captured Alexandria. The Fatimid heir-apparent, al-Qa'im bi-Amr Allah, then arrived to take over the campaign. Attempts to conquer the Egyptian capital, Fustat, were beaten back by the Abbasid troops in the province. A risky affair even at the outset, the arrival of Abbasid reinforcements from Syria and Iraq under Mu'nis al-Muzaffar doomed the invasion to failure, and al-Qa'im and the remnants of his army abandoned Alexandria and returned to Ifriqiya in May 915. The failure did not prevent the Fatimids from launching another unsuccessful attempt to capture Egypt four years later. It was not until 969 that the Fatimids conquered Egypt and made it the centre of their empire.

Ahmadibn al-Hasan al-Kalbi was the second Kalbid Emir of Sicily. He was the son of the first Kalbid emir, al-Hasan ibn Ali al-Kalbi, who ruled the island on behalf of the Fatimid Caliphate. Ahmad succeeded his father in May 953 until 968, apart from a brief interruption in 958/9. In the 960s, he led the completion of the Muslim conquest of Sicily by capturing the last Byzantine strongholds of Taormina and Rometta and defeating a Byzantine relief expedition. He was recalled to Ifriqiya to participate in the upcoming Fatimid conquest of Egypt, and died there shortly after.
