History of Iran

Qajar Dynasty, 1794 - 1925

Agha Mohammad Khan

The Qajars were a Turkmen tribe that held ancestral lands in present-day Azerbaijan, which at that time was part of Iran. In 1779, following the death of Mohammad Karim Khan of Zand dynasty, ruler of southern Iran, Agha Mohammad Khan, the leading figure of the Qajar tribe, set out to reunify the fragmented country. Over the following years, he defeated numerous rivals and gradually brought most of Iran under his control, laying the foundations of the Qajar dynasty. By 1794, he had eliminated all major opponents, including Lotf Ali Khan, the last ruler of the Zand dynasty, and had reasserted Iranian authority over former territories in Georgia and the Caucasus.

Agha Mohammad Khan was known for his harsh discipline and uncompromising methods, which helped him restore central authority after decades of civil war. He established his capital at Tehran, then a small settlement near the ruins of the ancient city of Ray (modern Shahr-e Rey), a location chosen for its strategic central position. In 1796, he was formally crowned shah, marking the official establishment of the Qajar dynasty.

In addition to consolidating internal rule, Agha Mohammad Khan also led campaigns to secure Iran’s northern frontiers, reasserting control over parts of the Caucasus that had slipped away during the period of chaos. His rule, however, was cut short when he was assassinated in 1797 while campaigning in Karabakh. He was succeeded by his nephew, Fath Ali Shah.

Fath Ali Shah, 1797 - 1834
Under Fath Ali Shah, Iran went to war with Russia, which was expanding southward from the Caucasus into regions of historic Iranian interest and influence. Iran suffered major military defeats during the conflict. Under the terms of the Treaty of Golestan in 1813, Iran recognized Russia’s annexation of Georgia and ceded most of the northern Caucasus region. A second war with Russia in the 1820s ended even more disastrously for Iran, and in 1828 it was forced to sign the Treaty of Turkmanchai, acknowledging Russian sovereignty over all territories north of the Aras River (including present-day Armenia and the Republic of Azerbaijan).

These defeats marked a major turning point in Iranian history, revealing the growing military and technological gap between Iran and the expanding European powers. The loss of the Caucasus also significantly reduced Qajar prestige and weakened central authority.

Fath Ali Shah’s reign also saw increased diplomatic contact with European powers and the beginning of intense imperial rivalry over influence in Iran. His grandson, Mohammad Shah, the son of Crown Prince Abbas Mirza, succeeded him in 1834. Abbas Mirza had earlier played a key role in attempts to modernize the Iranian army and administration in response to repeated defeats by Russia. When Mohammad Shah died in 1848, the throne passed to his son, Naser-e-Din Shah, who proved to be one of the most capable and significant rulers of the Qajar dynasty. His long reign marked the beginning of cautious modernization efforts in Iran, including limited administrative reforms and increased engagement with European powers, although these changes were often constrained by internal resistance and financial weakness.

During Naser al-Din Shah’s reign, Western science, technology, and educational methods were introduced into Iran, marking the beginning of a cautious modernization process. He established new schools, encouraged limited administrative reforms, and sent students to Europe, although these changes remained uneven and restricted by political and financial constraints.

Naser al-Din Shah attempted to exploit the mutual rivalry between Great Britain and Russia in order to preserve Iran’s independence, but foreign interference and territorial encroachment steadily increased under his rule. To finance his administration and his expensive personal journeys to Europe, he contracted large foreign loans, which further increased Iran’s financial dependence on European powers. He was unable to prevent Britain and Russia from expanding into regions of traditional Iranian influence.

In 1856, Britain prevented Iran from reasserting control over Herat, a city that had been part of Iran during the Safavid period but had remained outside Iranian rule since the mid-eighteenth century. Britain supported Herat’s incorporation into Afghanistan, a state it helped consolidate as a buffer between its Indian empire and Russia’s expanding influence in Central Asia. Britain also extended its control over strategic areas of the Persian Gulf during the nineteenth century.

Meanwhile, by 1881 Russia had completed its conquest of present-day Turkmenistan and Uzbekistan, pushing its frontier directly to Iran’s northeastern borders and severing long-standing Iranian cultural and commercial links with cities such as Bukhara and Samarkand. A series of trade concessions granted by the Iranian government placed key sectors of the economy increasingly under British influence. By the late nineteenth century, growing segments of the Iranian population believed that their rulers had become heavily dependent on foreign powers.

Mirza Taghi Khan Amir Kabir was the young Shah Naser al-Din’s chief advisor and chief minister (sadr-e aʿzam). Following the death of Mohammad Shah in 1848, Mirza Taqi Khan played a crucial role in securing the succession of the crown prince to the throne. When Naser al-Din Shah ascended the throne, Amir Kabir was appointed prime minister and granted the title Amir Kabir (“the Great Commander”).

Iran at this time was in a state of severe crisis: the central government was weak, the country was virtually bankrupt, and many provinces operated with a high degree of autonomy. Over the next two and a half years, Amir Kabir introduced a wide range of reforms across nearly all sectors of government and society. State expenditure was drastically reduced, and for the first time a clear distinction was made between the private treasury of the shah and the public treasury. The administrative system was reorganized, and Amir Kabir concentrated authority over much of the bureaucracy in his own hands in an effort to strengthen central control.

Foreign interference in Iran’s internal affairs was reduced where possible, and efforts were made to encourage controlled foreign trade on more favorable terms. Public works projects were initiated, including improvements to Tehran’s bazaar and urban infrastructure. Amir Kabir also issued an edict prohibiting excessively ornate and overly formal bureaucratic writing, marking an important step toward the development of a simpler and more modern Persian prose style.

One of Amir Kabir’s greatest achievements was the establishment of the Dar al-Fonun, the first modern institution of higher education in Iran. It was founded to train a new generation of administrators and to familiarize them with Western sciences and technical knowledge. Amir Kabir deliberately located the school on the outskirts of Tehran to allow for future expansion. He recruited instructors from Europe, including French and Russian teachers, alongside Iranian scholars, to teach subjects such as languages, medicine, law, geography, history, economics, and engineering. Although Amir Kabir did not live to see the institution fully flourish, the Dar al-Fonun became a lasting symbol of his vision for Iran’s modernization.

These reforms provoked strong opposition from powerful court factions and elites who had been excluded from government influence. They viewed Amir Kabir as a social upstart and a threat to their privileges, and they formed a coalition against him, in which the queen mother played a leading role. She ultimately convinced the young shah that Amir Kabir was seeking to usurp the throne. In October 1851, Amir Kabir was dismissed from office and exiled to Kashan, where he was soon murdered on the shah’s orders.

Mozaffar o-Din Shah

The Constitutional Revolution
When Naser al-Din Shah was assassinated by Mirza Reza Kermani in 1896, the crown passed to his son, Mozaffar al-Din Shah. Mozaffar al-Din Shah proved to be a weak and ineffective ruler. Royal extravagance and the absence of sufficient state revenue exacerbated Iran’s financial difficulties. The shah quickly exhausted two large loans obtained from Russia, much of which was spent on expensive personal trips to Europe.

Public discontent grew, fueled by resentment over the shah’s practice of granting concessions to European interests in exchange for personal payments to himself and his officials. As economic hardship deepened and foreign influence—particularly Russian—expanded, demands increased for the limitation of royal authority and the establishment of the rule of law.

The government’s failure to respond effectively to protests from the religious establishment, merchants, and other social groups led to a major political crisis. In January 1906, merchants and clerical leaders took sanctuary (bast) in mosques in Tehran and surrounding areas to avoid arrest and to press their demands. When the shah failed to fulfill his promise to establish a “house of justice,” or consultative assembly, approximately 10,000 people, led by merchants and supported by clerics, took sanctuary in June in the compound of the British legation in Tehran.

Under mounting pressure, the shah issued a decree in August promising a constitution. In October, an elected assembly convened and drafted a constitution that imposed strict limitations on royal authority and established an elected parliament (Majles) with significant powers to represent the people. It also provided for a cabinet government subject to parliamentary approval. The shah signed the constitution on December 30, 1906, and died only five days later.

The Supplementary Fundamental Laws, approved in 1907, further defined constitutional governance, providing—within limits—for freedom of the press, speech, and association, as well as guarantees of security of life and property. The Constitutional Revolution marked the end of the traditional monarchical order in Iran and the beginning of modern constitutional politics, although the hopes for stable constitutional rule were not immediately realized.

Mozaffar al-Din Shah’s son, Mohammad Ali Shah (r. 1907–1909), with the support of Russia, attempted to rescind the constitution and abolish parliamentary government. After a series of disputes with members of the Majles, he used his Russian-officered Persian Cossack Brigade in June 1908 to bombard the Majles building, arrest numerous deputies, and close down the assembly.

Resistance to the shah, however, soon emerged and coalesced in Tabriz, Isfahan, Rasht, and other cities. In July 1909, constitutional forces advanced from Rasht and Isfahan toward Tehran, deposed Mohammad Ali Shah, and restored the constitution. The deposed shah subsequently went into exile in Russia.

Ahmad Shah

Although the constitutional forces had triumphed, they soon faced serious difficulties. The upheavals of the Constitutional Revolution and the ensuing civil war had severely undermined stability and disrupted trade. In addition, the ex-shah, with Russian support, attempted to regain the throne, landing troops in July 1910.

Most significantly, the expectation that the Constitutional Revolution would usher in a new era of independence from the great powers was undermined by the Anglo-Russian Agreement of 1907, under which Britain and Russia agreed to divide Iran into spheres of influence. Russia was granted exclusive rights to pursue its interests in the northern zone, Britain in the southern and eastern zones, while a neutral central zone remained open to competition between the two powers.

The situation escalated further with the appointment of Morgan Shuster, an American financial administrator hired by the Persian government as treasurer-general to reform the country’s finances. Shuster’s efforts to collect taxes from powerful officials under Russian protection, and his attempts to extend the authority of the treasury gendarmerie into the Russian sphere, provoked strong Russian opposition. When, in December 1911, the Majles unanimously rejected a Russian ultimatum demanding Shuster’s dismissal, Russian troops already stationed in Iran moved toward the capital.

To prevent further escalation, on December 20 Bakhtiari chiefs and their forces surrounded the Majles building, compelled acceptance of the Russian demands, and dissolved the assembly, once again suspending the constitution. This was followed by a period of government dominated by Bakhtiari leaders and other influential notables.

Ahmad Shah Qajar was born on 21 January 1898 in Tabriz. He succeeded to the throne at the age of 11 and proved unable to preserve either the authority of the monarchy or the territorial integrity of Iran. His reign was marked by political weakness and instability, and he is often described as a pleasure-loving and ineffective ruler in contrast to the urgent demands of the period.

The occupation of Iran during the First World War (1914–1918) by Russian, British, and Ottoman forces dealt a severe blow to the authority of the Qajar state, from which Ahmad Shah never fully recovered. In the aftermath of the war, central authority continued to erode, while new political forces emerged.

Following the coup d’état of February 1921, Reza Khan (later Reza Shah Pahlavi, r. 1925–1941) rose rapidly to become the dominant political figure in Iran. Ahmad Shah was formally deposed by the Majles in October 1925 while he was abroad in Europe, and the assembly declared the Qajar dynasty to have ended, transferring sovereignty to the Pahlavi line.

Ahmad Shah died on 21 February 1930 in Neuilly-sur-Seine, France.
