Ayatollah Seyyed Ali Khamenei served as the Supreme Leader of Iran from 1989 until his death on February 28, 2026, making him one of the longest-ruling political and religious figures in modern Middle Eastern history. Born on April 19, 1939, in the holy city of Mashhad, Khamenei came from a religious family and pursued Islamic studies from an early age. He later moved to Qom, Iran’s spiritual center, where he studied under prominent clerics, including Ayatollah Ruhollah Khomeini, who would later become the founder of the Islamic Republic.
Revolutionary Activism and Rise to Power
Khamenei became politically active in the 1960s, joining the opposition against Shah Mohammad Reza Pahlavi. He was arrested multiple times by SAVAK (the Shah’s secret police) for spreading Khomeini’s teachings and advocating for Islamic governance. His early activism laid the foundation for a career that would intertwine religious authority with revolutionary politics.
Following the 1979 Islamic Revolution, Khamenei quickly rose through the ranks of the new Islamic Republic. He was appointed to the Revolutionary Council and became one of the architects of the Islamic Republic’s political system. In 1981, after the assassination of President Mohammad-Ali Rajai, Khamenei was elected President of Iran. He served two consecutive terms until 1989, navigating the country through the devastating Iran-Iraq War and internal political purges.
Despite not being a high-ranking cleric at the time of Khomeini’s death in 1989, Khamenei was chosen by the Assembly of Experts to succeed him as Supreme Leader. To facilitate this transition, a constitutional amendment removed the requirement that the Supreme Leader be a marjaʿ (source of emulation), allowing for a broader interpretation of religious authority.
Decades of Supreme Leadership
As Supreme Leader, Khamenei held the highest authority in Iran, with control over the armed forces, judiciary, state media, and final say in all major domestic and foreign policies. He appointed key figures in the government, including half of the members of the Guardian Council, which vetted electoral candidates and legislation. His influence shaped every branch of the Iranian state, making him the ultimate decision-maker in the Islamic Republic.
Khamenei’s tenure was marked by his emphasis on preserving the revolutionary ideals of 1979, particularly the concept of velayat-e faqih (Guardianship of the Islamic Jurist). Under his leadership, Iran maintained a posture of resistance against Western influence, particularly from the United States and Israel. He frequently referred to the U.S. as the “Great Satan” and was a vocal critic of what he called Western imperialism and cultural invasion.
Regional Strategy and the “Axis of Resistance”
Regionally, Khamenei pursued a policy of strategic depth by supporting allied groups and governments, including Hezbollah in Lebanon, the Assad regime in Syria, and various Shi’a militias in Iraq and Yemen. This approach expanded Iran’s regional influence but also contributed to rising tensions with neighboring countries and Western powers.
The regional landscape shifted dramatically during Khamenei’s final years. The October 2023 Hamas attack on Israel and subsequent regional conflicts sharpened international focus on Iran’s proxy network. By summer 2024, Iran and its allies faced significant setbacks, including the killing of multiple Hamas leaders, major losses for Lebanese Hezbollah, the fall of the Assad regime in Syria in late 2024, and direct military exchanges between Israel and Iran in which Iran appeared to suffer greater damage than it inflicted.
In February 2025, U.S. President Donald Trump announced renewed “maximum pressure” on Iran to end its nuclear threat, curtail its ballistic missile program, and stop its support for terrorist groups. In March 2025, Trump sent a letter to Khamenei encouraging negotiations on Iran’s nuclear program with a two-month deadline; talks involving U.S. and Iranian diplomats began in April 2025 and continued through May.
Domestic Challenges and Economic Crisis
Domestically, Khamenei faced numerous challenges, including crippling economic sanctions, corruption, and sustained public discontent. Waves of protests—notably in 2009, 2017, 2019, and during the 2022–2023 “Woman, Life, Freedom” movement following Mahsa Amini’s death—tested the regime’s stability. In response, Khamenei consistently aligned with hardliners, advocating for crackdowns rather than reforms. The government’s response grew increasingly brutal, with security forces killing thousands of protesters and arresting tens of thousands more during the December 2025 demonstrations.
Economically, Khamenei promoted the concept of a “resistance economy” aimed at reducing Iran’s dependence on foreign powers and countering the effects of international sanctions. However, this model failed to address the country’s deep-rooted structural problems. By mid-2025, the Iranian rial had collapsed to a historic low of 1 million rials to the U.S. dollar. Inflation soared above 43%, wiping out the purchasing power and life savings of ordinary Iranians. The economy suffered from profound dependence on oil exports—which accounted for approximately 70% of total exports—but international sanctions had slashed official oil exports from a peak of over 2.5 million barrels per day to just 20% of that volume by 2024.
Succession Speculation and Death
At 86 years old, questions regarding Khamenei’s succession had become increasingly pertinent. Previously, his protégé, hard-line President Ebrahim Raisi, was considered a likely successor, but Raisi was killed in a May 2024 helicopter crash. This left Khamenei’s second son, Mojtaba Khamenei—a 56-year-old mid-level cleric with strong ties to the Islamic Revolutionary Guard Corps (IRGC) but no government experience—as a leading contender, despite his father’s reported opposition to hereditary succession.
Other potential successors included Ayatollah Alireza Arafi, a senior cleric who served as deputy chairman of the Assembly of Experts and was appointed to the provisional Leadership Council; Mohammad Mehdi Mirbagheri, an ultra-hardline voice in the Assembly of Experts; and Hassan Khomeini, the reformist grandson of the Islamic Republic’s founder, who commanded respect among some IRGC elements and senior clerics.
On February 28, 2026, Ayatollah Khamenei was killed in a surprise U.S. and Israeli bombardment targeting Iran’s leadership. The strike marked the end of his 37-year rule and triggered only the second succession crisis in the Islamic Republic’s history.
Aftermath and Transition
Following Khamenei’s death, a provisional governing council composed of President Masoud Pezeshkian, hard-line judiciary chief Gholamhossein Mohseni Ejei, and senior cleric Ayatollah Alireza Arafi was formed to guide the country through the transition. The 88-member Assembly of Experts is tasked with selecting a new Supreme Leader, with a decision expected within days.
Khamenei’s death marks a pivotal moment for Iran. His leadership defined the country’s post-revolutionary identity for nearly four decades, and his departure creates uncertainty about whether the Islamic Republic will maintain its current trajectory of confrontation with the West or potentially open the door to significant change. As one analyst noted, “A post-Khamenei Iran is not necessarily a post-Islamic Republic of Iran,” referencing the regime’s proven resilience through numerous domestic and foreign crises.
