أحمد بن طولون
In 868, Caliph al-Mu'tazz (r. 866–869) gave charge of Egypt to the Turkish general Bakbak. Bakbak in turn sent his stepson Ahmad ibn Tulun as his lieutenant and resident governor. This appointment ushered in a new era in Egypt's history: hitherto a passive province of an empire, under Ibn Tulun it would re-emerge as an independent political centre. Ibn Tulun would use the country's wealth to extend his rule into the Levant, in a pattern followed by later Egypt-based regimes, from the Ikhshidids to the Mamluk Sultanate.
