Iran awoke to a moment of profound shock on February 28 as state media announced the death of its long-serving supreme leader, Ayatollah Ali Khamenei. He was 86. According to official accounts, his death followed a major military assault on Iranian territory carried out jointly by Israel and the United States, an escalation that marked a historic turning point for the Islamic Republic and the wider Middle East.
Khamenei had ruled Iran for nearly four decades, rising to the position of supreme leader in 1989 after the death of Ayatollah Ruhollah Khomeini. Throughout his tenure, he stood as the central figure of Iran’s political system, shaping both its internal governance and its confrontational posture abroad. His leadership was defined by a strict interpretation of Islamic rule, resistance to Western influence, and unwavering hostility toward Israel—positions that earned him loyal supporters at home and formidable enemies beyond Iran’s borders.
Born in 1939 in the northeastern city of Mashhad to a deeply religious family of Azeri origin, Khamenei was drawn early to clerical life. He pursued advanced religious studies in Qom, where he came under the influence of Khomeini, whose revolutionary ideas would shape his political destiny. A poet and intellectual by temperament, Khamenei nevertheless committed himself fully to revolutionary activism, enduring repeated arrests under the rule of Shah Mohammad Reza Pahlavi.
The 1979 Islamic Revolution transformed Khamenei from a dissident cleric into a rising figure within the new Islamic Republic. Appointed to lead Tehran’s Friday prayers and entrusted with key roles in national defence, he steadily gained prominence. His survival of an assassination attempt in 1981, which left him permanently injured, further elevated his status and preceded his election as president later that year. He served two terms during the devastating Iran-Iraq war, positioning himself at the heart of Iran’s wartime leadership.
Khamenei’s ascent to supreme leader in 1989 was controversial and swift. Though initially viewed as a compromise choice lacking the highest clerical credentials, he moved decisively to consolidate power. Through constitutional changes and political maneuvering, he transformed the office into the ultimate authority over Iran’s military, judiciary, media, and electoral system, firmly entrenching the doctrine of clerical supremacy over the state.
At home, his rule was repeatedly challenged by waves of public dissent. Student protests, the Green Movement of 2009, economic demonstrations, and the nationwide uprising sparked by the death of Mahsa Amini in 2022 were all met with harsh crackdowns. Security forces, including the Revolutionary Guards, played a central role in suppressing opposition, reinforcing a climate of fear that allowed the regime to endure despite mounting public anger.
Internationally, Khamenei presided over one of the most contentious chapters in modern Middle Eastern politics. Iran’s nuclear programme placed him at the centre of prolonged confrontations with Western powers and Israel, resulting in sweeping sanctions that severely weakened Iran’s economy. Although he reluctantly endorsed the 2015 nuclear agreement, its collapse following the US withdrawal in 2018 reignited tensions and accelerated Iran’s nuclear ambitions.
Khamenei also sought to expand Iran’s influence across the region through a network of allied militant groups, an “axis of resistance” spanning Lebanon, Gaza, Yemen and beyond. However, years of conflict gradually eroded this strategy. Israeli military campaigns weakened Iran’s regional allies, while political upheaval in Syria further reduced Tehran’s influence.
By mid-2025, the conflict entered a direct and unprecedented phase. Israeli airstrikes targeted Iranian military and nuclear facilities, triggering retaliatory missile and drone attacks. When the United States joined the offensive, Iran’s leadership was forced into hiding as its defensive capabilities were strained. Despite a ceasefire, the pressure on Khamenei intensified, with Israeli leaders openly declaring him a legitimate target.
His death now closes a defining era in Iran’s history. For supporters, Khamenei embodied resistance and ideological continuity; for critics, he symbolised repression and missed opportunities for reform. As Iran confronts an uncertain future without the man who shaped its modern identity, the consequences of his rule—and of his violent end—are likely to reverberate far beyond its borders.
