The Ayyubid Sultanate's leader Saladin acquired the town from the Zengids in 1182. During Ayyubid rule, Edessa had a population of approximately 24,000. The Sultanate of Rûm took Edessa in June 1234, but sometime in late 1234 or 1235, the Ayyubid sultan Al-Kamil re-acquired it. After Edessa had been recaptured, Al-Kamil ordered the destruction of its Citadel. Not long after, the Mongols had made their presence known in Edessa in 1244. Later, the Ilkhanate sent troops to Edessa in 1260 at which point the town voluntarily submitted to them. The populace of Edessa were thus saved from being massacred by the Mongols. Edessa was also held by the Mamluk Sultanate, and the Aq Qoyunlu.
