This dossier traces the Islamic Republic of Iran from Ruhollah Khomeini’s return in February 1979: the monarchy’s overthrow, the hostage crisis, the Iran-Iraq War, Ali Khamenei’s succession, sanctions, domestic protests and nuclear negotiations. It also follows regional confrontation through Tehran’s allies, rapprochement with Saudi Arabia and the transition to direct Iran-Israel attacks in 2024. The twelve-day war of June 2025 is distinguished from the conflict opened on 28 February 2026 by US and Israeli strikes. The chronology examines Ali Khamenei’s killing and Mojtaba Khamenei’s succession, civilian victims, regional fronts, energy infrastructure, Hormuz, blockades and attempts at agreement. The Qatari consultations that originally defined this dossier remain integrated into the expanded history. Sourced entries distinguish established facts, announcements, attributed responsibility and unverified outcomes. The reconstruction selects principal milestones rather than recording every military operation. No final, consistent human toll across all theatres is established here. Dates without a known time are ordered by calendar day.
