Ayatollah Seyyed Mojtaba Hosseini Khamenei is the third Supreme Leader of the Islamic Republic of Iran, who was elected as the Supreme Leader of the Islamic Republic by the Assembly of Experts after the martyrdom of his father, the former Leader of the Islamic Revolution, and the deaths of his wife, mother, and some other close family members in a terrorist attack on the Supreme Leader's residence. The beginning of his leadership came at one of the most sensitive and tense periods in Iran's contemporary history, and had a wide-ranging impact on the domestic and regional space.

Seyyed Mojtaba Khamenei was born in the city of Mashhad. He is the second son of Seyyed Ali Khamenei, the former martyred Leader of the Islamic Republic of Iran, and comes from a family known for religious, revolutionary, and cultural activities. His mother was also from a religious and cultural family that lived alongside the former Leader of the Revolution for many years.

Despite their high political and social status, this family has continued to focus on raising their children and maintaining family unity over the past years, and has always kept their distance from the media.

Seyyed Mojtaba Khamenei pursued his religious education at the Qom Seminary and learned an important part of jurisprudence and principles from prominent professors. After years of scientific and research presence at the seminary, he also taught and trained students and played an effective role in teaching and spreading Islamic knowledge.

During a terrorist attack that targeted Tehran, Seyyed Ali Khamenei, the former leader of the Islamic Republic of Iran, was martyred. At the same time, his wife, mother, and a number of other close family members also lost their lives. This incident was one of the most bitter and important events in Iran's contemporary history and had a profound impact on the country's political, social, and security environment.

Following this tragic incident, the Assembly of Experts held an extraordinary session and, by vote of its members, elected Seyyed Mojtaba Hosseini Khamenei as the third Supreme Leader of the Islamic Republic of Iran. This election was made in a situation where the country was facing security and regional threats and pressures, and maintaining internal stability and continuing the path of the revolution were considered the most important priorities.

With the beginning of Seyyed Mojtaba Khamenei’s leadership, the Islamic Republic of Iran entered a new stage in its history. He is known as the third leader after Ruhollah Khomeini and Seyyed Ali Khamenei, and the responsibility of maintaining internal cohesion, guiding the path of the Islamic Revolution, and confronting regional and international threats has been placed on his shoulders.
