Who is Ayatollah Alireza Arafi? Iran’s 'seasoned cleric' now appointed to interim council

Iran has appointed Ayatollah Alireza Arafi as its interim Supreme Leader, a key step in the country’s leadership transition following the death of longtime leader Ayatollah Ali Khamenei in joint US–Israeli airstrikes on Tehran early Saturday.

Arafi, a senior cleric and long-time insider in Iran’s religious and political hierarchy, now faces the challenge of guiding the Islamic Republic amid heightened regional tensions and domestic uncertainty.

Arafi’s rise within the clerical establishment

Born in 1959 in Meybod, Yazd province, Arafi comes from a clerical family and has spent decades within Iran’s theological and bureaucratic institutions. He studied in Qom under prominent religious scholars and earned the rank of mujtahid, qualifying him to issue independent Islamic legal rulings.

His career advanced under Khamenei, who appointed him to key roles, including leading Friday prayers in Meybod and later in Qom, signalling trust from the top leadership.

Arafi also chaired Al-Mustafa International University, a major centre for training clerics from Iran and abroad, and in 2019 joined the powerful Guardian Council, which vets legislation and electoral candidates.

Analysts note that his mix of administrative and theological roles firmly positions him within Iran’s clerical elite, and his appointment maintains continuity in the country’s religious hierarchy.

Constitutional path to leadership

Under the Iranian Constitution, the supreme leader must be a senior Shia cleric chosen by the Assembly of Experts, an elected body of religious scholars. Following Khamenei’s death, an interim leadership council is formed to carry out essential functions until the Assembly selects a permanent successor. Arafi’s Guardian Council and Assembly positions gave him institutional leverage in the succession process, amid other potential candidates from hard-line and pragmatic clerical factions.

Arafi’s outlook and role

Arafi has publicly emphasised the role of seminaries and clerics in promoting politically engaged Shi’a Islam, highlighting solidarity with the oppressed and an international outlook. In previous remarks, he stated: “Seminaries need to be from the people, in solidarity with the downtrodden, be political, revolutionary, and international in approach.”

While Arafi has extensive experience and strong establishment credentials, he lacks an independent political base outside institutional structures—a factor likely to influence his leadership amid external conflicts and internal uncertainty.

A pivotal transition in Tehran

Khamenei, who ruled Iran for nearly 37 years, was killed on February 28, 2026, triggering a succession process and nationwide mourning. Arafi’s appointment marks only the second transition of supreme leadership since the 1979 Islamic Revolution, testing Iran’s political framework and its ability to maintain cohesion under pressure. As he assumes Iran’s highest office, international attention will focus on how he balances religious authority with geopolitical pressures and domestic stability in the coming months.
