Majd ad-Dīn Usāma ibn Murshid ibn ʿAlī ibn Munqidh al-Kināni al-Kalbi (also Usamah, Ousama, etc.; ) (July 4, 1095 – November 17, 1188) was a medieval Muslim poet, author, faris (professional warrior), and diplomat from the Banu Munqidh dynasty of Shaizar in northern Syria. His life coincided with the rise of several medieval Muslim dynasties, as well as the arrival of the First Crusade and the establishment of the crusader states. Most of his family was killed in an earthquake at Shaizar in 1157. He died in Damascus in 1188, at the age of 93, a remarkably advanced age for the time.
