The Qajars (also spelled Kadjars, Kajars, Kadzhars, Cadzhars, Cadjars and so on) are a Turkic Oghuz tribe who lived variously, with other tribes, in the area that is now Armenia, Azerbaijan and northwestern Iran. They are considered as a branch of the Azerbaijanis. In the 17th and 18th centuries the Kajars resisted the Safavids and settled the Karabakh Khanate. In 1794, a Kajar chieftain, Agha Mohammed, founded the Qajar dynasty which replaced the Zand dynasty in Iran. In the 1980s the Kajar population exceeded 15,000 people, most of whom lived in Iran.
