What Happened
- Ayatollah Ali Khamenei, Iran's Supreme Leader since 1989, was killed in joint US-Israeli airstrikes on February 28, 2026, triggering Iran's constitutional succession process for only the second time in the Islamic Republic's history.
- The Assembly of Experts — an 88-member elected body of Islamic jurists — is constitutionally mandated to select the next Supreme Leader under Article 107 of the Iranian Constitution.
- No designated successor had been officially named before Khamenei's death, making the transition uniquely contested and uncertain.
- Potential candidates reported include Khamenei's son Mojtaba Khamenei, former judiciary chief Sadeq Larijani, Ali Larijani (senior civilian official), and Hassan Khomeini (grandson of the Islamic Republic's founder).
- Father-to-son succession is considered constitutionally and culturally problematic in a revolutionary republic that came about by toppling a monarchy.

Velayat-e-Faqih: The Doctrine of Supreme Leadership
Velayat-e-faqih (Guardianship of the Islamic Jurist) is the founding constitutional and theological doctrine of the Islamic Republic of Iran, introduced by Ayatollah Ruhollah Khomeini after the 1979 Islamic Revolution. It holds that in the absence of the Hidden (Twelfth) Imam of Shia Islam, political authority must be exercised by the most qualified Islamic jurist. This concept transformed Iran from a constitutional monarchy into a theocratic republic.
- Enshrined in Articles 5, 107, and 110 of the Iranian Constitution (1979, revised 1989).
- The Supreme Leader holds powers over all three branches of government, commands armed forces, declares war and peace, and appoints heads of judiciary and security forces.
- The doctrine combines elements of democracy (elected Assembly of Experts) and theocracy (religious qualification requirement for the leader).
- Khomeini held the position from 1979 until his death in 1989; Khamenei has held it from 1989 until 2026.
Connection to this news: Khamenei's death activates the succession mechanism embedded in velayat-e-faqih doctrine — a mechanism never previously used after the initial installation of Khamenei.
Assembly of Experts: Constitutional Role and Limitations
The Assembly of Experts (Majles-e Khobregan) is an 88-member deliberative body of Islamic jurists elected by popular vote for eight-year terms. It holds the constitutional authority to appoint, supervise, and — in theory — dismiss the Supreme Leader. However, all candidates to the Assembly must first be vetted and approved by the Guardian Council, whose members are themselves appointed (directly or indirectly) by the Supreme Leader, creating a circular power structure.
- Constitutional basis: Article 107 (election of Supreme Leader), Article 111 (supervision and dismissal).
- Members must be Mujtahids — Islamic jurists qualified to exercise independent legal reasoning (ijtihad).
- Has never once dismissed or formally questioned a sitting Supreme Leader in its entire history, leading many observers to describe it as more ceremonial than independent.
- The Guardian Council's screening of candidates for the Assembly effectively gives the Supreme Leader indirect control over who selects the next Supreme Leader.
- Current Assembly was elected in March 2024 for an eight-year term.
Connection to this news: The Assembly's sudden activation in a crisis situation — with the Supreme Leader killed rather than dying peacefully — is unprecedented and tests whether the body can act with genuine independence.
Guardian Council: The Screening Mechanism
The Guardian Council (Shora-ye Negahban) is a 12-member body — 6 Islamic jurists appointed directly by the Supreme Leader, and 6 legal experts nominated by the judiciary chief (also a Supreme Leader appointee) and approved by Parliament. It reviews all legislation for conformity with Islamic law and the Constitution, and vets all candidates for elected offices including Parliament, Presidency, and the Assembly of Experts.
- Has sweeping disqualification powers: routinely bars hundreds of candidates from elections.
- Effectively acts as a gatekeeping mechanism that ensures ideological conformity throughout the system.
- All candidates to the Assembly of Experts must pass Guardian Council vetting, meaning the Supreme Leader's appointees effectively control who can select the next Supreme Leader.
- Has disqualified reformist candidates from elections repeatedly, most notably ahead of the 2004, 2012, and 2024 elections.
Connection to this news: The Guardian Council's pre-screened Assembly now faces the unprecedented task of selecting a new Supreme Leader in a wartime crisis, raising questions about whether the system's circular power structures can function legitimately.
Iran's Political System: A Dual-Track Architecture
Iran operates a unique dual-track political system that combines elected republican institutions with unelected theocratic bodies. The President, Parliament (Majlis), and Assembly of Experts are all elected but operate under the overarching authority of the Supreme Leader and Guardian Council. The Islamic Revolutionary Guard Corps (IRGC) — a parallel military force separate from the regular army — reports directly to the Supreme Leader.
- President manages executive affairs but the Supreme Leader controls foreign policy, military, and judiciary.
- Expediency Council (Majma-e Tashkhis) resolves disputes between Parliament and Guardian Council; its chair has sometimes been mentioned as a possible Supreme Leader.
- IRGC's political role has grown significantly under Khamenei, making it a key stakeholder in the succession process.
- Iran has had only two Supreme Leaders in 47 years — Khomeini (1979–1989) and Khamenei (1989–2026).
Connection to this news: The succession will reveal whether the Islamic Republic's institutions are strong enough to ensure an orderly transfer of power, or whether factional competition within the IRGC and clerical establishment will destabilize the system.
