Qara Mahammad Khan was the second khan of the Qara Qoyunlu from 1380 to 1389. He was the nephew and successor of Bayram Khwaja and father of Qara Yusuf.
Qara Mahammad (Azerbaijani: Qara Məhəmməd قارا محمد) was a bey of the Qara Qoyunlu and father of Qara Yusuf.
Life
Mahammad was a nephew of Bayram Khwaja and one of his main supporters. He served Jalayirid sultan Uways and suppressed Khwaja Marjan's rebellion (governor of Baghdad) for him, installing his uncle Murad as governor of Baghdad. However, their relations deteriorated soon after.
Uways captured Baghdad from Murad in 1364 and advanced to fight Bayram and Qara Mahammad's armies in Muş. Together they conquered Mosul, Erciş, Mayafariqin and Van. New Jalayirid sultan Hussain moved against Muhammad and attacked Erciş, his new base. Despite Bayram Khwaja's help, Qara Qoyunlus suffered heavy casualties and were captured. Hussain too was deposed soon by Ahmad Jalayir, who invaded Tabriz with the assistance of Shirvanshah Hushang (although Minorsky noted a certain Hamza who was a son of Farrukh Yassar being his supporter, it's chronologically impossible).
Ahmad's other brothers, Shaikh Ali and Pir Ali Barik, opposed him. Husain's former amir, Adil Aqa, had Bayazid proclaimed sultan in Soltaniyeh, while Shaikh Ali prepared to leave Baghdad and march on Tabriz. To secure his position, Ahmad requested the assistance of Qara Mahammad. Shaikh Ali fell in battle against the Qara Yusuf on September 1382. Pir Ali was also killed in 1383.
