Qajar Iran

The Guarded Domains of Iran, alternatively the Sublime State of Iran and commonly called Qajar Iran, Qajar Persia or the Qajar Empire, was the Iranian state under the rule of the Qajar dynasty, which was of Turkic origin, specifically from the Qajar tribe, from 1789 to 1925. The Qajar family played a pivotal role in the Unification of Iran (1779–1796), deposing Lotf 'Ali Khan, the last Shah of the Zand dynasty, and re-asserted Iranian sovereignty over large parts of the Caucasus. In 1796, Agha Mohammad Khan Qajar seized Mashhad with ease, putting an end to the Afsharid dynasty. He was formally crowned as Shah after his punitive campaign against Iran's Georgian subjects.

In the Caucasus, the Qajar dynasty permanently lost much territory to the Russian Empire over the course of the 19th century, comprising modern-day eastern Georgia, Dagestan, Azerbaijan, and Armenia. Despite its territorial losses, Qajar Iran reinvented the Iranian notion of kingship and maintained relative political independence, but faced major challenges to its sovereignty, predominantly from the Russian and British empires. Foreign advisers became powerbrokers in the court and military. They eventually partitioned Qajar Iran in the 1907 Anglo-Russian Convention, carving out Russian and British influence zones and a neutral zone.

In the early 20th century, the Persian Constitutional Revolution created an elected parliament or Majles, and sought the establishment of a constitutional monarchy, deposing Mohammad Ali Shah Qajar for Ahmad Shah Qajar, but many of the constitutional reforms were reversed by an intervention led by the Russian Empire. Qajar Iran's territorial integrity was further weakened during the Persian campaign of World War I and the invasion by the Ottoman Empire. Four years after the 1921 Persian coup d'état, the military officer Reza Shah took power in 1925, thus establishing the Pahlavi dynasty, the last Iranian royal dynasty.

Since the Safavid era, Mamâlek-e Mahruse-ye Irân (Guarded Domains of Iran) was the common and official name of Iran. The idea of the Guarded Domains illustrated a feeling of territorial and political uniformity in a society where the Persian language, culture, monarchy, and Shia Islam became integral elements of the developing national identity. The concept presumably had started to form under the Mongol Ilkhanate in the late 13th century, a period in which regional actions, trade, written culture, and partly Shia Islam, contributed to the establishment of the early modern Persianate world. Its shortened variant was mamalik-i Iran ("Domains of Iran"), most commonly used in the writings from Qajar Iran.

A late legend holds that the Qajars first came to Iran in the 11th-century along with other Oghuz Turkic clans. However, the Qajars neither appear in the Oghuz tribal lists of Mahmud al-Kashgari nor Rashid al-Din Hamadani. It has been speculated that the Qajars were originally part of a larger tribal group, with the Bayats often considered the most likely tribe from which they later separated. According to the same late legend, the Qajar tribe's namesake ancestor was Qajar Noyan, said to be the son of a Mongol named Sartuq Noyan, who reportedly served as atabeg to the Ilkhanate ruler Arghun (r. 1284–1291). This legend also claims that the Turco-Mongol ruler Timur (r. 1370–1405) was descended from Qajar Noyan. Based on the claims of the legend, Iranologist Gavin R. G. Hambly reconstructed the early history of the Qajars in a hypothetical manner, suggesting that they immigrated towards Anatolia or Syria following the collapse of the Ilkhanate in 1335. Then, during the late 15th century, the Qajars resettled in the historical region of Azerbaijan, becoming affiliated with the neighbouring Erivan, Ganja and Karabakh. Like the other Oghuz tribes in Azerbaijan and eastern Anatolia during the rule of the Aq Qoyunlu, the Qajars likely also converted to Shia Islam and adopted the teachings of the Safavid order.

The Qajar tribe first started to gain prominence during the establishment of the Safavids. When Ismail led the 7,000 tribal soldiers on his successful expedition from Erzincan to Shirvan in 1500/1501, a contingent of Qajars was among them. After this, they emerged as a prominent group within the Qizilbash confederacy, who were made up of Turkoman warriors and served as the main force of the Safavid military. Despite being smaller than other tribes, the Qajars continued to play a major role in important events during the 16th century.

The Safavids "left Arran (present-day Republic of Azerbaijan) to local Turkic khans", and, "in 1554 Ganja was governed by Shahverdi Soltan Ziyadoglu Qajar, whose family came to govern Karabakh in southern Arran". Qajars filled a number of diplomatic missions and governorships in the 16–17th centuries for the Safavids. The Qajars were resettled by Shah Abbas I throughout Iran. The great number of them also settled in Astarabad (present-day Gorgan, Iran) near the south-eastern corner of the Caspian Sea, and it would be this branch of Qajars that would rise to power. The immediate ancestor of the Qajar dynasty, Shah Qoli Khan of the Quvanlu of Ganja, married into the Quvanlu Qajars of Astarabad. His son, Fath Ali Khan (born c. 1685–1693) was a renowned military commander during the rule of the Safavid shahs Sultan Husayn and Tahmasp II. He was killed in 1726. Fath Ali Khan's son Mohammad Hasan Khan Qajar (1722–1758) was the father of Mohammad Khan Qajar and Hossein Qoli Khan Qajar (Jahansouz Shah), father of "Baba Khan," the future Fath-Ali Shah Qajar. Mohammad Hasan Khan was killed on the orders of Karim Khan of the Zand dynasty.

Within 126 years between the demise of the Safavid state and the rise of Naser al-Din Shah Qajar, the Qajars had evolved from a shepherd-warrior tribe with strongholds in northern Persia into a Persian dynasty with all the trappings of a Perso-Islamic monarchy.
