Abu 'Amr 'Uthman (Arabic: أبو عمرو عثمان, romanized: Abū ʿAmr ʿUthmān; February 1419 – September 1488), regnal title al-Mutawakkil 'ala Allah (Arabic: المتوكل على الله, romanized: al-Mutawakkil ʿala Allāh, "he who relies on God")[1] was the Hafsid ruler of Ifriqiya, or modern Tunisia, eastern Algeria and western Libya, who reigned between 1435 and 1488.

A Flemish merchant who arrived at his court in Tunis in 1470 described him as tall, thoughtful, just, and pious, and called him the "greatest, most powerful, and richest of all Moorish princes.

[8] In early 1437, the Awlad Abi-l-Layl chieftains were captured and brought in chains to the citadel of Tunis, but Abu-l-Hasan continued the rebellion, this time with the support of the tribes of Kabylia.

On November 9 of that year, Uthman's troops captured Béjaïa for the first time, where Abu-l-Hasan had minted currency in his own name and otherwise took on the trappings of a legitimate Islamic monarchy.

[8] In the 1440s, Uthman also personally engaged in military campaigns towards the south, against the autonomous inland towns of Nefta and Touggourt, and subdued them to central control.

[9] Diplomatically, Uthman encouraged European merchants to visit Ifriqiya by promising them the same justice that his own Muslim subjects would receive, and worked for amicable relations with the Christian Mediterranean powers.

[12] He also renewed and expanded treaties with the Italian republics of Venice and Genoa in 1438 and 1444 respectively, granting the latter a license to import large qualities of North African grain.

[14] In terms of internal governance, Uthman refrained from giving high office to fellow Hafsid dynasts and generally appointed royal retainers, often renegade Europeans, as qaids or provincial governors.

[17] In 1463, nomadic tribes in the North African interior, discontent with a decrease in the payments the Hafsid treasury customarily made to them, rose up against the throne.

When Abu Abdallah proved disloyal and attempted to ally with the insurgent tribes in the interior, Uthman launched another campaign in 1466 that reaffirmed Hafsid dominance over Tlemcen.

Unlike earlier Hafsids, Uthman remained largely uninterested in the security of the beleaguered Emirate of Granada, although friendly contacts between the two continued.

He also maintained ties with the Mamluks, a traditional friend, and established new ones with the Ottomans, sending a mission in 1454 to congratulate the sultan Mehmed II for his capture of Constantinople.

[29] The security of Sicily or the commercial economy of the port of Barcelona, both of which were adversely affected by bad relations with Uthman, was probably not of great interest to the Aragonese kings; John II of Aragon disliked Barcelona, which had rebelled against him, and his successor Ferdinand II was too preoccupied with the final conquest of Granada to pay relations with the Hafsids much heed.

[32] Despite the historical friendship between the Granadans and the Hafsids, Uthman did not respond to a 1487 mission from the former begging desperately for aid to save the kingdom from imminent demise.

[34][35] Abd-al-Mumin ibn Ibrahim was no more successful in winning over support and was soon overthrown by the eighteen-year-old son of his predecessor, Abu Yahya Zakariya.
