The Tulunids, were a Mamluk dynasty of Turkic origin who were the first independent dynasty to rule Egypt, as well as much of Syria, since the Ptolemaic dynasty. They were independent from 868, when they broke away from the central authority of the Abbasid Caliphate, to 905, when the Abbasids restored the Tulunid domains to their control.
Abu 'l-Jaysh Khumārawayh ibn Aḥmad ibn Ṭūlūn was a son of the founder of the Tulunid dynasty, Ahmad ibn Tulun. His father, the autonomous ruler of Egypt and Syria, designated him as his successor. When Ibn Tulun died in May 884, Khumarawayh succeeded him. After defeating an attempt to depose him, in 886 he managed to gain recognition of his rule over Egypt and Syria as a hereditary governor from the Abbasid Caliphate. In 893 the agreement was renewed with the new Abbasid Caliph, al-Mu'tadid, and sealed with the marriage of his daughter Qatr al-Nada to the Caliph.
The al-Madhara'i were a family of officials from Iraq who served as and virtually monopolized the posts of director of finances (‘āmil) of Egypt and Syria for the Tulunid dynasty, the Abbasid Caliphate, and the Ikhshidid dynasty, between 879 and 946. In this role, they amassed "one of the largest personal fortunes in the medieval Arab east".
Abu Bakr Muhammad ibn Ali al-Madhara'i (871–957) was the last important representative of the bureaucratic al-Madhara'i dynasty of fiscal officials. He served as director of finances of Egypt and Syria under the Tulunid dynasty and the Abbasid Caliphate, as well as becoming vizier for the Tulunid ruler Harun ibn Khumarawayh, and later occupying high office under the Ikhshidids.
