Ahmad ibn Tulun
A son of the dynasty's founder, Ahmad ibn Tulun, he succeeded his nephew Harun ibn Khumarawayh, who was killed in a mutiny in December 904 during the invasion of Egypt by the Abbasid Caliphate. After years of mismanagement, the emirate was beyond rescue - he was forced to retreat with his army to Fustat, where on 10 January 905 he surrendered unconditionally to the Abbasid commander Muhammad ibn Sulayman al-Katib, ending the rule of the Tulunids.
