Ahmad ibn Tulun
The Tūlūnid administration over Egypt bore several notable features. The style of rule was highly centralized and "pitiless" in its execution. The administration was also backed by Egypt's commercial, religious and social élite. Ahmad ibn Tulun replaced Iraqi officials with an Egyptian bureaucracy. Overall, the administration relied on the powerful merchant community for both financial and diplomatic support. For example, Maʿmar al-Ḏj̲awharī, a leading member of the merchant community in Egypt, served as Ibn Ṭūlūn's financier.
