Qajar period brass vessel with Islamic inscription around the neck and decorated by panels populated by figures within the star polygon frames. Qajar Dynast Agha Mohammad Khan The Qajars were a Turkmen tribe that held ancestral lands in present-day Azerbaijan, which then was part of Iran. In 1779, following the death of Mohammad Karim Khan Zand, the Zand Dynasty ruler of southern Iran, Agha Mohammad Khan, a leader of the Qajar tribe, set out to reunify Iran. Agha Mohammad Khan defeated numerous rivals and brought all of Iran under his rule, establishing the Qajar dynasty. By 1794 he had eliminated all his rivals, including Lotf 'Ali Khan, the last of the Zand dynasty, and had reasserted Iranian sovereignty over the former Iranian territories in Georgia and the Caucasus. Agha Mohammad established his capital at Tehran, a village near the ruins of the ancient city of Ray (now Shahr-e Rey). In 1796 he was formally crowned as shah.
