On 16 January 1979, the Shah fled Iran, leaving behind a collapsing monarchy and a revolutionary tide that would reshape the Middle East. From that upheaval emerged a new political order, an Islamic Republic built on the doctrine of clerical rule. Nearly half a century later, the system created in revolution has been shaken by another upheaval, one that ended with the death of the man who embodied it for more than three decades.Ayatollah Ali Khamenei, Iran’s second Supreme Leader, rose from the ranks of revolutionary clerics to become the most powerful figure in the Islamic Republic. He survived assassination attempts, war, sanctions and repeated waves of protest. He outlasted presidents at home and adversaries abroad. In the end, however, it was war with the United States and Israel, the very confrontation that had defined much of his rule, that brought it to a close.His death, confirmed by Iranian state media after extensive US and Israeli air strikes on Tehran, closes a chapter that began with the overthrow of a monarch and concludes with the violent unravelling of a revolutionary state. Born in resistance, the Islamic Republic was shaped by struggle. Under Khamenei, it hardened into a system that tolerated neither dissent nor compromise.
From Mashhad seminarian to supreme authority
Born in 1939 in Mashhad to a clerical family, Khamenei was shaped by religious study and political dissent. As a young cleric he studied in Qom under Khomeini and was arrested multiple times by the Shah’s security services for anti-regime activism. After the 1979 revolution, he rose swiftly: Friday prayer leader in Tehran, then president during the brutal Iran–Iraq war.In 1981 he survived an assassination attempt that paralysed his right arm. The experience deepened his suspicion of rivals and foreign enemies. When Khomeini died in 1989, Khamenei lacking his mentor’s senior clerical rank, was unexpectedly elevated by the Assembly of Experts to the role of supreme leader.

Initially viewed as weak, he moved carefully to consolidate authority. Constitutional changes strengthened the office. Over time, he built networks of loyalists across the judiciary, parliament, state media and the clerical establishment, transforming himself from compromise candidate into the system’s undisputed arbiter.
Building a security state
Central to Khamenei’s power was the Islamic Revolutionary Guard Corps (IRGC). He expanded it into Iran’s dominant military and economic force, granting it oversight of the ballistic missile programme and vast commercial interests. In return, it became his most reliable instrument of control.The Basij militia and intelligence services were repeatedly deployed to crush dissent. Student protests in 1999 were put down. The 2009 “Green Movement”, which erupted after a disputed presidential election, was suppressed with arrests and force. Economic protests in 2017 and 2019 met similar fates.
The most profound domestic rupture came in 2022 after the death in custody of Mahsa Amini, detained for allegedly breaching Iran’s strict dress code. Demonstrations led by women and young people spread nationwide. Hundreds were killed, thousands arrested. Khamenei framed the unrest as foreign-instigated sedition and refused concessions on compulsory hijab or political reform.His final and bloodiest crackdown followed a currency collapse that drove the rial to record lows. When protesters again chanted “Death to the dictator”, he declared that “rioters must be put in their place”. Security forces opened fire. Activists reported thousands killed. It was a show of force that revealed both the regime’s resilience and its fear.
Confrontation with the West and regional ambition
If repression defined Khamenei’s domestic rule, confrontation marked his foreign policy. He consistently cast the United States as Iran’s principal adversary, accusing it of seeking regime change. The 1979–81 US embassy hostage crisis, supported by revolutionary leaders including Khamenei, cemented decades of hostility.Under his watch, Iran pursued an expansive regional strategy. Through allies and proxies – from Hezbollah in Lebanon to Hamas in Gaza and the Houthis in Yemen – Tehran projected influence while avoiding direct war. Khamenei viewed Israel as illegitimate and supported armed resistance as both ideological duty and strategic leverage.Iran’s nuclear programme became the central flashpoint. The 2015 Joint Comprehensive Plan of Action (JCPOA) offered sanctions relief in exchange for limits on enrichment. Khamenei endorsed it cautiously, describing tactical compromise as “heroic flexibility”. When the United States withdrew in 2018 and reimposed sanctions, Iran gradually breached the deal’s limits.
Years of sanctions, mismanagement and corruption hollowed out the economy. Inflation soared, oil revenues dwindled and public anger deepened. Yet Khamenei refused to abandon missile development or regional alliances, seeing them as essential deterrents.His final months were marked by escalating brinkmanship. As US forces massed in the region and Israel struck Iranian assets, he warned that any attack would trigger wider war. Negotiations flickered but faltered. Then came the strikes that targeted key military sites – and his own compound.
An uncertain future
Khamenei’s death leaves no publicly confirmed successor. Constitutionally, the Assembly of Experts must appoint a new supreme leader. Speculation has ranged from senior clerics to his son Mojtaba. The IRGC, now the country’s most powerful institution, may play a decisive role in any transition.Iran stands at a crossroads. The system Khamenei inherited from revolution he hardened into a security state sustained by ideology, patronage and force. Yet beneath it lies a society weary of isolation, economic hardship and repression.
