Ayatollah Ali Khamenei

Overview

Ayatollah Seyyed Ali Hosseini Khamenei, the second and longest-serving supreme leader of the Islamic Republic of Iran, was killed on February 28, 2026, when a US-Israeli airstrike struck his compound in Tehran. He was 86 years old. His mother, wife, and one sister were also killed in the attack.

His death — the targeted killing of a sitting head of state — was the most significant assassination of a national leader in decades and the immediate catalyst for a regional war spanning at least 12 countries.

Early Life and Rise

Born on April 19, 1939, in Mashhad, Iran’s second-largest city, Khamenei came from a family of Islamic scholars. He studied theology in Qom under prominent clerics and became involved in opposition to the Shah’s government in the 1960s, which led to multiple imprisonments and periods of internal exile.

Khamenei was an early supporter of Ayatollah Ruhollah Khomeini’s revolutionary movement and participated in the 1979 Islamic Revolution that overthrew the Pahlavi monarchy. His role in the revolution established him as a trusted figure within the new theocratic state.

President and Supreme Leader

Khamenei served as Iran’s third president from 1981 to 1989, a period dominated by the Iran-Iraq War (1980-1988). His presidency was characterized by the management of a devastating conflict that killed hundreds of thousands and defined a generation of Iranian political and military leaders.

Upon the death of Ayatollah Khomeini in 1989, the Assembly of Experts selected Khamenei as supreme leader — a decision that surprised some observers, as he was not considered the most senior cleric in Iran’s religious hierarchy. He held the position for nearly 37 years, making him one of the longest-serving heads of state in the modern Middle East.

Power and Authority

As supreme leader, Khamenei held ultimate authority over Iran’s armed forces, nuclear program, foreign policy, judiciary, and state media. The position placed him above the elected president and parliament, giving him effective veto power over all significant state decisions.

He oversaw the expansion of Iran’s ballistic missile program, the development of its nuclear enrichment capabilities, and the cultivation of a network of allied militias across the Middle East — including Hezbollah in Lebanon, various groups in Iraq, the Houthis in Yemen, and Hamas in Palestine.

Under his leadership, Iran’s regional influence expanded significantly, even as the country faced increasingly severe international sanctions targeting its economy, financial system, and oil exports.

Domestic Legacy

Khamenei’s domestic legacy was deeply contested. Supporters credited him with maintaining Iran’s independence, developing its military capabilities, and preserving the Islamic Republic’s governing system through multiple crises.

Critics held him responsible for the suppression of political dissent, including the violent crackdown on the 2009 Green Movement protests and the 2022 Mahsa Amini uprising. Under his authority, Iran’s security forces killed hundreds of protesters and detained thousands, drawing widespread international condemnation.

His son, Mojtaba Khamenei, was linked to the coordination of security force operations during both the 2009 and 2022 protests — a connection that would become relevant when Mojtaba was selected as his father’s successor.

The Nuclear Question

Khamenei consistently maintained that Iran’s nuclear program was for peaceful purposes and issued religious edicts against the development of nuclear weapons. However, Western intelligence agencies and the International Atomic Energy Agency repeatedly expressed concerns about possible military dimensions of the program.

The 2015 Joint Comprehensive Plan of Action (JCPOA) — the nuclear agreement with world powers — was negotiated during his tenure, though Khamenei maintained public skepticism about Western intentions throughout the process. The agreement’s collapse following the US withdrawal in 2018 reinforced his longstanding distrust of diplomatic engagement with Washington.

Death and Aftermath

The strike that killed Khamenei on February 28, 2026, was part of a coordinated US-Israeli military campaign that hit targets across Iran. The targeting of a sitting head of state in his own capital represented an escalation without modern precedent among major world powers.

Iran’s response was immediate and sweeping. The IRGC launched retaliatory attacks across nine countries, targeting 27 or more US military bases and Israeli positions. The conflict quickly expanded to include Hezbollah’s entry on March 2 and sustained attacks on Gulf states hosting US forces.

On March 8, the Assembly of Experts selected Khamenei’s son, Mojtaba Khamenei, as the third supreme leader — the first dynastic succession in the Islamic Republic’s history.

Legacy

Ayatollah Ali Khamenei shaped Iran and its role in the Middle East for nearly four decades. His killing in a targeted strike, and the regional war it triggered, ensured that his death would be as consequential as his life. The Islamic Republic he led survived him, but the conflict sparked by his assassination was, as of March 13, still expanding — with no end in sight.
