Uzun Hasan or Uzun Hassan (Persian: اوزون حسن; February or March 1425 – January 5, 1478) was a ruler of the Turkoman Aq Qoyunlu state and is generally considered to be its strongest ruler. Hasan was from the Bayandur tribe and presided over the confederation's territorial apex, when it included parts or all of present-day Iraq, Turkey, Azerbaijan, Iran, Transcaucasia, and Syria. The younger son of Ali Beg and Sara Khatun, Hasan rose to prominence during the protracted Aq Qoyunlu civil war of the 1440s and 1450s.
