Previous supreme leader: Ali Khamenei (1989–2026) ·
First supreme leader: Ruhollah Khomeini (1979–1989) ·

Who is the main leader of Iran?

The role of the Supreme Leader

  • Highest state authority, controls military, judiciary, and media
  • Appointed by the Assembly of Experts (Council on Foreign Relations (leadership transition research))
  • Article 111 of the constitution provides for an interim council if the leader dies (Carnegie Endowment for International Peace)

The Supreme Leader’s authority extends over all branches of government. The pattern: ultimate power rests with one figure, not with elected bodies.

Who is the current Supreme Leader?

  • Mojtaba Khamenei, son of Ali Khamenei, was selected in March 2026 (Al Jazeera (Qatari news network))
  • The Assembly of Experts reached a majority agreement on his appointment

Why this matters: A hereditary succession in a revolutionary republic carries immense political risk, testing the regime’s claims of merit-based leadership.

The paradox

Iran’s 1979 revolution rejected monarchy, yet the supreme leadership may now pass from father to son — a contradiction the regime must navigate.

Does Iran have a president or a dictator?

The president’s role in Iran

  • The president is head of government, elected by popular vote
  • Manages the executive branch but lacks final say on defense and foreign policy

Three roles, one hierarchy: president, Supreme Leader, and the Assembly of Experts create a system that is neither pure democracy nor absolute dictatorship.

How the Supreme Leader differs from a president

  • Supreme Leader controls the military, judiciary, and state media
  • President oversees ministries and day-to-day administration
  • The Supreme Leader can dismiss the president (Wikipedia (encyclopedic reference))

The takeaway: Iran operates with a dual executive, but all serious decisions ultimately require the Supreme Leader’s approval.

Does Iran have a new leader now?

Succession after Ali Khamenei’s death

What this means: The constitution provided a roadmap, but the speed of the transition suggests intense behind‑the‑scenes maneuvering.

Mojtaba Khamenei’s background

  • Son of Ali Khamenei, previously served as head of the Iranian president’s office
  • Known for hardline views and close ties to the Islamic Revolutionary Guard Corps

The implication: His selection consolidates power within the Khamenei family.

What to watch

Mojtaba Khamenei must prove he can command the loyalty of the military and the clerical establishment on his own, without relying on his father’s legacy.

What does ayatollah mean?

Ayatollah as a religious title

  • “Ayatollah” means “sign of God” in Arabic
  • It is a high‑ranking title in Shia Islam, granted to scholars of exceptional knowledge

The context: Only a handful of clerics earn this title, which carries immense religious authority.
