Iran’s Supreme Leader Ayatollah Ali Khamenei, who led the Islamic Republic since 1989, is dead at 86

Iran’s Supreme Leader Ayatollah Ali Khamenei Killed in US-Israeli Strike

Ayatollah Ali Khamenei, Iran’s supreme leader who wielded theocratic power for over three decades and positioned Iran as a regional force against Western interests, has been killed in joint US-Israeli strikes. He was 86.

Iranian state media confirmed his death early Sunday following a major military operation. US President Donald Trump announced hours earlier that Khamenei had been killed in the coordinated attack.

Khamenei’s daughter, son-in-law, a grandchild, and a daughter-in-law also perished in the strike, according to the semi-official Fars news agency. The Iranian government declared 40 days of public mourning and a seven-day nationwide holiday.

The death marks a pivotal moment for the Islamic Republic, which Khamenei helped shape after succeeding Ayatollah Ruhollah Khomeini in 1989. While Khomeini was the fiery revolutionary who overthrew the Western-backed Shah Mohammad Reza Pahlavi, Khamenei—initially viewed as a less charismatic figure with weaker religious credentials—transformed the revolutionary vision into an entrenched political system.

During his tenure, Khamenei dramatically expanded the power of the Revolutionary Guard, turning it into both a military and business behemoth with control over significant portions of Iran’s economy and its ballistic missile arsenal. His leadership was characterized by consistent hostility toward the United States and Israel, particularly regarding Iran’s controversial nuclear program.

“He ended up ruling far longer than Khomeini,” noted regional analysts, who point out that Khamenei’s 35-year reign shaped modern Iran more profoundly than his predecessor’s decade in power.

In recent years, however, Khamenei’s grip on power faced mounting challenges. A faltering economy under international sanctions fueled growing domestic unrest. The 2022 death of Mahsa Amini, detained for not wearing her mandatory headscarf properly, sparked nationwide protests against the regime’s social restrictions. By early this year, hundreds of thousands of Iranians were marching in cities across the country, many openly calling for Khamenei’s downfall.

The regime responded with brutal force. Security forces opened fire on crowds in what observers called the deadliest crackdown in nearly 50 years of clerical rule, resulting in thousands of deaths.

Internationally, Khamenei’s carefully constructed “Axis of Resistance”—a network of proxy forces including Hamas, Hezbollah, Yemen’s Houthi rebels, and militias in Iraq and Syria—began collapsing following Hamas’ October 7, 2023 attack on Israel. The subsequent conflicts led to direct military exchanges between Israel and Iran for the first time in 2024, with Israel striking Iranian targets and killing top military officers and nuclear scientists.

Under Khamenei’s leadership, Iran accelerated its nuclear program despite international pressure. Following Trump’s 2018 withdrawal from the 2015 nuclear deal, Iran ramped up uranium enrichment to near-weapons-grade levels. While Khamenei issued a verbal fatwa declaring nuclear weapons un-Islamic, Western intelligence agencies maintained that Iran preserved the capability to develop such weapons if it chose to do so.

The supreme leader’s death creates significant uncertainty about Iran’s future. The 88-seat Assembly of Experts, a group of predominantly hard-line clerics, is responsible for choosing his successor, but no clear heir apparent exists. President Trump, in announcing the strikes on Saturday, called on Iranians to “take over your government. It will be yours to take. This will be probably your only chance for generations.”

Analysts suggest the Revolutionary Guard, which has repeatedly demonstrated its willingness to use overwhelming force to maintain power, will play a crucial role in determining what happens next, even as many among Iran’s 90 million people have grown increasingly disenchanted with the theocratic system.

“Culturally, the government is bankrupt,” said Mehdi Khalaji, an analyst at the Washington Institute for Near East Policy. “The ideology of the Islamic Republic did not work at all.”

Born in the northeastern holy city of Mashhad, Khamenei studied under Khomeini before joining the anti-Shah movement, experiencing both imprisonment and periods in hiding. After the 1979 revolution, he served as Iran’s president from 1981 until Khomeini’s death, when he was elevated to supreme leader despite initial questions about his religious credentials.

His legacy will be defined by his expansion of clerical power, confrontation with the West, and the brutal suppression of calls for reform—leaving Iran at a critical crossroads as the Islamic Republic faces perhaps its most significant transition since its founding.
