The appointment of Mojtaba Khamenei as Iran’s new Supreme Leader comes at a time of profound turmoil for the Islamic Republic. The announcement was made shortly after midnight on Monday by the Assembly of Experts, the powerful clerical body responsible for selecting the country’s highest authority. The decision followed the death of his father, Ayatollah Ali Khamenei, who was reportedly killed in US–Israeli airstrikes earlier this month.

With Iran under intense military pressure and facing growing domestic uncertainty, the Assembly’s move appears aimed at maintaining continuity within the country’s political and religious leadership.

A discreet figure long seen as influential

For years, Mojtaba Khamenei had been widely viewed as a possible successor to his father, despite never holding a formal government position. He was ultimately selected over other prominent contenders, including cleric Alireza Arafi, hardliner Mohsen Araki, and Hassan Khomeini, the grandson of Iran’s revolutionary founder.

Born on September 8, 1969, in the northeastern city of Mashhad, Mojtaba is one of six children of Ali Khamenei, who served as Iran’s Supreme Leader for more than three decades.

Though he rarely appeared in public or held official posts, Mojtaba gradually built influence within Iran’s clerical and political establishment. His limited media presence and quiet involvement in political circles fueled years of speculation about his role behind the scenes. At 56, he becomes the second Supreme Leader chosen by the Assembly of Experts since the 1979 Islamic Revolution.

Religious education and clerical background

Mojtaba Khamenei pursued religious studies in Qom, Iran’s leading center of Shiite scholarship. He later taught Islamic studies there and attained the clerical rank of Hujjat al-Islam, a mid-level religious title below the rank of ayatollah held by his father.

His status as a seyyed—someone believed to be a descendant of the Prophet Muhammad—has also reinforced his religious standing within Iran’s clerical establishment.

Connections with the Revolutionary Guards

Mojtaba has long been regarded as having close ties to Iran’s powerful security institutions, particularly the Islamic Revolutionary Guard Corps (IRGC). His association with the force reportedly dates back to the final years of the Iran-Iraq War in the 1980s, when he served in a combat unit.

Over the years, analysts and diplomats have suggested that he developed strong relationships with conservative factions and security officials, allowing him to wield considerable influence within Iran’s power structure despite lacking a formal political role.

US sanctions and controversy

In 2019, the United States imposed sanctions on Mojtaba Khamenei, accusing him of acting as a representative for his father in political matters and cooperating with Iranian security forces to advance government policies at home and abroad.

Critics inside Iran have also alleged that he played a role in the crackdown on protests following the disputed 2009 re-election of President Mahmoud Ahmadinejad, although these claims have never been officially confirmed.

Investigations by international media have further suggested that Mojtaba Khamenei accumulated significant wealth through financial networks linked to oil revenues and overseas investments.

A rare dynastic transition

Mojtaba Khamenei’s selection marks an unusual moment in Iran’s political system. The 1979 Islamic Revolution had overthrown the monarchy and ended centuries of dynastic rule under the Shah. Despite that legacy, the Assembly of Experts ultimately chose the son of the late Supreme Leader, prioritizing stability during a period of war and political uncertainty.

Israel has already issued warnings to Iran’s new leadership, signaling that regional tensions remain high as Mojtaba Khamenei assumes the country’s most powerful position.
