Ziyadoghlu Qajar (Azerbaijani: Ziyadoğlu Qacar, زیاد اوغلو قاجار, lit. 'Qajars (who are) sons of Ziyad') or Ziyadlu (Persian: زیادلو) were a branch of the Qajar tribe[1] that governed Safavid Karabakh from 1546[2]–1554[3][4] to 1743 (sometimes, also including Safavid Kakheti[5][6]), Astarabad[1] in various times, Ganja Khanate from 1747 to 1805.[7] Some authors suggested that, Qovanlu branch of Qajars who ruled Iran from 1789 to 1925, which is currently better known as Qajar dynasty was a cadet-branch of Ziyadoghlu family.[8]
