This biography traces the life of Ali Khamenei, from his modest upbringing as the son of an Azeri cleric to his long tenure as the Supreme Leader of Iran. The text details his early religious education, his active resistance against the Shah’s secular regime, and the 1981 assassination attempt that left him with permanent physical disabilities. Following the death of Ayatollah Khomeini, Khamenei emerged as a compromise successor, gradually shifting the nation toward a more authoritarian and conservative stance while expanding the power of the Revolutionary Guard. His leadership is defined by the pursuit of a nuclear program, the management of a proxy network including Hezbollah and Hamas, and a persistent cycle of domestic protests and international sanctions. Ultimately, the source evaluates his legacy as one of regional influence and internal repression, currently facing significant challenges from Israeli and American military actions.
