JAHAN SHAH

Jahan also spelled Jihan (reigned c. 143867), leader of the Turkmen Kara Koyunlu (q.v.; Black Sheep) in Azerbaijan. Under Jahan Shah's rule the Kara Koyunlu extended their domain over Iraq, Fars, and Esfahan (1453). In 1458 he invaded Khorasan and seized Herat from the Timurid Abu Sa'id, but the growing power of the Ak Koyunlu (q.v.; White Sheep) under Uzun Hasan (q.v.) brought about an agreement between Abu Sa'id and Jahan Shah to divide Iran between them. Defeated by the Ottoman Turks in 1461, Uzun Hasan fought the Kara Koyunlu and defeated and killed Jahan Shah in 1467.
