Al-Ashraf Khalil

Al-Malik Al-Ashraf Salāh ad-Dīn Khalil ibn Qalawūn (Arabic: الملك الأشرف صلاح الدين خليل بن قلاوون; c. 1260s – 14 December 1293) was the eighth Turkic Bahri Mamluk sultan, succeeding his father Qalawun. He served from 12 November 1290 until his assassination in December 1293. He was well known for conquering the last of the Crusader states in Palestine after the siege of Acre in 1291. While walking with a friend, Khalil was attacked and assassinated by Baydara (his commander in chief) and his followers, who was then killed under the orders of Kitbugha.
