al-Mu'tadid I

Al-Mu'tadid I (المعتضد) was the sixth holder of the revived Abbasid caliphate of Cairo under Mamluk rule, held office from 1352 until his death in 1362, and he belonged to the line of eighteen Abbasids invested as caliphs in Egypt between 1261 and 1517.^{1 • 9}

Background: the Abbasid caliphate in Mamluk Cairo

The Abbasid caliphate had been re-established in Cairo by the Mamluk sultan al-Ẓāhir Baybars after Baghdad fell to the Mongols in 656/1258; Baybars installed successively two refugee Abbasids as caliphs in his capital, and the official account by his court biographer Muḥyī al-Dīn Ibn ʿAbd al-Ẓāhir needs supplementing and correction, according to P. M. Holt, the School of Oriental and African Studies historian of the Mamluk period.⁵

Throughout the Mamluk period the ulama maintained the earlier stipulation that the holder of the caliphal office had to have Qurayshi and Hashimite credentials, and the caliphs served as conduits providing a link to the family of the Prophet.³ By the mid-fourteenth century, the period of al-Mu'tadid's reign, the caliphs had lost political and religious significance, yet they retained a measure of religious authority and enjoyed the reverence of noteworthy sectors of the Cairene population, including religious scholars, chroniclers, chancery scribes, poets, and travelers.^{6 • 1}

The office in practice: installation, ceremony and daily reality

Installation. One recorded caliph's accession followed this ceremonial procedure. The caliph went up to the citadel, where the grand judges, the amirs, and the shaykh al-islām Sirāj al-Dīn ʿUmar al-Bulqīnī presided; the sultan opened the session and swore allegiance (bayʿa) first, then the others swore according to their rank, and the caliphal robe was bestowed according to custom.⁷ A second robe was given at the mashhad al-nafīsī, a custom the chronicler notes was recent rather than ancient among the caliphs of Egypt.⁷

The oath and its direction. Holt held that after Baybars the caliph's presence at investiture ceremonies became "technically indispensible," but that the direction of the oath reversed over time: originally the caliph received the sultan's bayʿa, yet soon the caliph, as a court pensioner, gave bayʿa to the sultan alongside the four chief judges.¹ Chroniclers nonetheless continued to record sultans receiving the oath from the caliph at accession, for example al-Ṣāliḥ Ḥājjī in 783/1381 and Muḥammad b. Qāyitbāy in 901/1496.⁵

Symbols of sovereignty. Caliphal names were inscribed on coinage and pronounced in the Friday khutba only from the reign of Sultan al-Nasir Muhammad ibn Qalawun, Baybars having initially denied even this right.²

Daily reality. The caliphs were confined to the Citadel or to the family residence in the district of al-Kabsh in the early Mamluk sultanate. They were often tutored in the Islamic sciences and were expected to engage in the practice of praying for the government and the sultan's success, and to busy themselves in pious exercises with members of the established religious elite.⁴ The caliph's political role was confined to formally investing new sultans, ceremonial visits, and nominal membership in the sultan's council, with no real influence over decisions such as declarations of war.² A resident caliph did lend immediate prestige to Mamluk diplomatic relations with Muslim allies and competitors.⁴

Reign 1352–1362 and the sultans he served

The general rule of the institution framed his end. The caliph resided in a tower of the Citadel of the Mountain under the sultan's watch, and if he displayed any action that aroused the sultan's suspicion, the sultan would not hesitate to depose, imprison, or even kill him, and to appoint another Abbasid in his place; the specific circumstances of al-Mu'tadid's death in 1362 are not established in the sources cited here.² More broadly, when a caliph ventured into Mamluk politics, whether voluntarily or not, it tended to result in shame and exile.⁴ Ibn Taghribirdi's chronicle mentions him only in a later context, in 788 AH (October–November 1386), when the sultan summoned the Abbasid Zakaryā to succeed his brother al-Wāthiq and Zakaryā's uncle al-Muʿtaḍid gave him a diploma as successor of the caliph.⁷

Religious role and practice

The caliph appeared most frequently at political ceremonies alongside the four chief qadis of Egypt, but he did not share their privileges and was not often consulted on religious matters; true religious authority remained with the ulama.⁴ His visible religious functions were limited, extending to attending Friday prayer at al-Azhar Mosque, and at times caliphs were even prevented from delivering the Friday sermon.² The Qurayshi and Hashimite lineage requirement, maintained by the ulama throughout the period, was the religious basis on which the office rested.³

By comparison: before and after al-Mu'tadid

Al-Mutawakkil ʿalā ʾllāh Muḥammad reigned 763–85/1362–83 and again 791–808/1389–1406, and over the course of his time in office he was offered the sultanate on at least three occasions, including at ʿAqaba in 1377, showing that caliphs could be courted for real power in the era immediately after al-Mu'tadid.³ Al-Mutawakkil was a descendant of al-Ḥākim bi-Amr Allāh (r. 660–701/1262–1302), the second Abbasid survivor installed by Baybars as caliph in Cairo, tying al-Mu'tadid's family to the founding generation of the Cairo line.³

Mustafa Banister, whose 2022 monograph covers the public and private lives of the eighteen caliphs, dates the period of "Flirtations with Power and Political Intrigue" to 763–815 AH / 1362–1412, that is, the era beginning immediately after al-Mu'tadid's death in 1362.⁸ His own decade fell before that phase, in the period when the caliphs' political and religious significance had already declined.⁶
