Annulment of 1975 Algiers Agreement by Saddam Hussein, Shahrivar 26. On this date in 1980, Saddam Hussein, the President of Iraq, officially annulled the Algiers Agreement, which had been signed between Iran and Iraq in 1975. The agreement was created to resolve border disputes, especially in the Shatt al-Arab region, and its annulment is regarded as one of the main triggers of the Iran-Iraq War. Saddam Hussein’s decision to revoke the treaty sharply escalated political and military tensions between the two countries. Only days after this event, the eight-year Iran-Iraq War began, resulting in widespread casualties. Estimates indicate that hundreds of thousands of people were killed or wounded on both sides during the conflict. This event remains significant in the modern history of Iran and Iraq, marking a turning point in bilateral relations and regional developments. This date was officially designated in the Jalali calendar in 1980 to commemorate the historical significance and consequences of the annulment. According to Islamic Republic sources, this observance is registered and presented in the official calendar in this form and with these descriptions.
