The chancellery office diwan al-insha, which drafted official correspondence, was headed during his rule by a scholar who continued to head it under Yusuf's descendants.[3](https://doi.org/10.1515/9781399536837-013) The poet Ibn al-Khayyat composed a panegyric praising Thiqat al-Dawla's military genius and restless energy, and presenting him as a powerful man who protected the people and the Islamic faith from the constant attacks of the Byzantines; the poem's purpose is to praise his character, achievements, and \"acts of kingship.\"[3](https://doi.org/10.1515/9781399536837-013)\n\n## Political influence\n\nA study of the dynasty based on the Fatimid chancellery source Sirat al-Ustadh [Jawdhar](https://www.edgepedia.org/jawdhar) describes the Kalbid Emirate of Sicily (359–444/970–1052) as a frontier principality affiliated with the Fatimids in foreign policy but autonomous in internal affairs, playing a decisive role in the caliphate's relations with the [Byzantine Empire](https://www.edgepedia.org/byzantine-empire) and the Umayyads of Andalusia.[1](https://dergipark.org.tr/en/pub/cihannuma/article/1723040) \n\nYusuf's own court left institutions that outlasted him: the diwan al-insha under Ibn al-Tubi continued in service under his descendants, and the stability of his reign consolidated the emirate's independence in practice.[3](https://doi.org/10.1515/9781399536837-013)\n\n## Death and successors\n\nKalbid rule remained in his family until the dynasty's fall.[2](https://arab-ency.com.sy/details/160237) One reference work counts ten Kalbid governors ruling about ninety years, from AH 336–427 / 947–1035, and dates the dynasty's end to AH 427 (1035–1036), when opponents overpowered al-Hasan [Samsam al-Dawla](https://www.edgepedia.org/samsam-al-dawla) al-Kalbi, who had succeeded al-Akhal after his killing, after which Sicily passed to the Normans;[2](https://arab-ency.com.sy/details/160237) another study dates the emirate AH 359–444 (970–1052)[1](https://dergipark.org.tr/en/pub/cihannuma/article/1723040) and a third gives its end, with brief interruptions, as 1053.[5](https://www.degruyterbrill.com/document/doi/10.1515/9781399536837-006/pdf)\n\n## Historians' assessment\n\nSerious sources converge on Yusuf's reign as the high point of Kalbid Sicily. The study of Sicilian poetic traditions states that during Kalbid rule, especially under Emir Yusuf al-Kalbi, Muslim Sicily reached its peak politically and culturally, and that Palermo became an important capital of the dar al-Islam and an intellectual center.[3](https://doi.org/10.1515/9781399536837-013) A study of the dynasty based on the Fatimid chancellery source Sirat al-Ustadh Jawdhar credits the Kalbids with bringing Muslim Sicily its most glorious period.[1](https://dergipark.org.tr/en/pub/cihannuma/article/1723040)\n\nThe dating of the dynasty itself is not settled among these sources: ten governors ruling about ninety years between AH 336–427 / 947–1035[2](https://arab-ency.com.sy/details/160237) stands against the emirate dated 359–444 / 970–1052[1](https://dergipark.org.tr/en/pub/cihannuma/article/1723040) and an end dated to 1053.[5](https://www.degruyterbrill.com/document/doi/10.1515/9781399536837-006/pdf) Yusuf's own regnal years likewise vary within the main scholarly study, which gives 990–98 in one passage and 989–98 in another.[3](https://doi.org/10.1515/9781399536837-013)\n\n## Legacy\n\nThe century of Kalbid rule saw Muslim Sicily flourish as an agricultural powerhouse and a center of Mediterranean trade.[5](https://www.degruyterbrill.com/document/doi/10.1515/9781399536837-006/pdf) The island under the dynasty saw progress in building, the sciences, and letters, alongside continuous struggle in southern Italy against Byzantine ambitions.[2](https://arab-ency.com.sy/details/160237)\n\n## References\n\n1.
