With his election as the supreme leader of Iran, Mojtaba Khamenei, the 56-year-old second son of the late Ali Khamenei, assumes sweeping control over the country’s political system, armed forces and religious establishment, placing him at the apex of power in a country deeply strained by war and internal divisions.
Under Iran’s constitutional framework, the supreme leader wields authority far beyond that of any elected official. He rules through decrees and religious opinions known as fatwas, sets the country’s broad foreign policy direction and commands the armed forces, including the powerful Islamic Revolutionary Guard Corps. He also appoints the heads of the judiciary, military commanders and the leadership of state broadcasting. While Iran elects a president through national elections, the supreme leader retains the power to approve the outcome and must formally endorse both the president and the cabinet.
The elevation of Mojtaba Khamenei marks a historic and controversial moment for the Islamic Republic. For the first time since the Iranian Revolution, Iran’s supreme leadership has passed directly from father to son. The revolution that toppled Mohammad Reza Pahlavi had promised to end hereditary rule and replace monarchy with a system rooted in Islamic jurisprudence and clerical authority. The emergence of what critics describe as a dynastic succession therefore, carries heavy symbolic weight.
Ali Khamenei himself had reportedly indicated to close advisers that he did not want his son to succeed him, precisely to avoid the appearance of dynastic rule. Yet the circumstances surrounding the transition appear to have overridden such concerns. Facing war, internal unrest and an uncertain political future, Iran’s power centres moved quickly to consolidate authority. Senior clerics, influential politicians such as Ali Larijani and commanders within the Revolutionary Guard rallied behind Mojtaba as a figure capable of preserving continuity within the system.
The 88-member Assembly of Experts convened under extraordinary conditions. Its traditional meeting complex in the clerical city of Qom had reportedly been damaged in an Israeli strike, forcing members to gather virtually to decide the country’s most consequential political appointment. In the end, the body bypassed several more moderate candidates, including senior cleric Alireza Arafi and reformist-leaning figure Seyed Hassan Khomeini, grandson of the revolution’s founder, Ruhollah Khomeini. The choice of Mojtaba signalled a determination among Iran’s ruling elite to maintain a hardline ideological course.
Until now, Mojtaba Khamenei has spent most of his life as a powerful yet largely unseen figure within the regime. Often described as the most influential member of his father’s inner circle, he has rarely appeared in public and has never held elected office. Many Iranians have never heard his voice in a speech or sermon, and photographs of him are scarce.
Born in the northeastern city of Mashhad in 1969, Mojtaba briefly served in the Habib Battalion during the Iran–Iraq War while still a teenager. After the war, he increasingly embedded himself within his father’s office, where he reportedly helped coordinate links between the clerical leadership and Iran’s security apparatus. Over time, he built close ties with the Revolutionary Guard and the paramilitary Basij militia, relationships that would later underpin his influence.
His name surfaced repeatedly during some of the Islamic Republic’s most contentious political crises. Critics have long accused him of playing a decisive role in the suppression of the 2009 protest movement that erupted after the disputed re-election of President Mahmoud Ahmadinejad. The demonstrations, widely known as the Iranian Green Movement, brought millions into the streets demanding electoral transparency. Reformist politicians such as Mehdi Karroubi and Mostafa Tajzadeh later accused Mojtaba of orchestrating security operations and manipulating political outcomes. Reports also suggest that he personally pressured opposition candidate Mir-Hossein Mousavi to abandon the protests while the latter was under house arrest.
Questions have also been raised about Mojtaba’s religious standing. While Iranian state media and supportive clerics have recently begun referring to him as an ayatollah, he has traditionally been regarded as a mid-ranking cleric, or hojatoleslam. He began formal seminary studies in Qom relatively late, reportedly around the age of 30, raising doubts among some clerics about whether he possesses the scholarly credentials historically expected of a Supreme Leader.
However, a constitutional amendment adopted in 1989 had already lowered those requirements, enabling Ali Khamenei himself to assume the position despite not holding the highest clerical rank. That precedent has now proved crucial in smoothing Mojtaba’s path to power.
Beyond religious questions, his financial influence has also drawn scrutiny. Western media investigations have linked him to networks controlling vast economic assets tied to foundations and state-aligned business interests. Some reports have connected figures close to him with the controversial collapse of Bank Ayandeh, which deepened Iran’s economic crisis by saddling the state with enormous unpaid debts.
International reaction to his appointment has been sharply divided. Iran’s regional allies welcomed the decision. Leaders of the Houthi movement in Yemen described the succession as a “resounding blow” to the enemies of the Islamic Republic, while Iran’s parliament speaker and military commanders quickly pledged allegiance to the new leader.
The response from Iran’s adversaries was clearly hostile. US President Donald Trump dismissed Mojtaba’s leadership as unacceptable and warned that the new supreme leader “is not going to last long” without Washington’s approval. Israeli officials were even more explicit. They have declared that any successor to Ali Khamenei would remain a potential military target, publicly identifying Mojtaba as a figure they would pursue if hostilities escalate further.
As supreme leader, Mojtaba Khamenei inherits authority at one of the most perilous moments in the Islamic Republic’s history. He takes power while Iran faces sustained military pressure, severe internal unrest and mounting economic strain. He will have to consolidate power, maintain the loyalty of the security forces and navigate a rapidly widening regional conflict that could determine the future of the Islamic Republic itself.
